It was still former, and we lay in bed together, holding each early, kissing, enjoying the consequence but both processing the logical implication of knowing that we were now both in love with each early. I hated the musical theme of Deni disbursal her life together with some married man who could not raise the inherent gender that was powerfully inside her, nor did I bask the idea of explaining to my daughter that I was in love with a woman almost the same age as her. Deni for certain dreaded the estimate of her husband finding out, or the messy divorce that would inevitably ensue, yet be both yearned to be with each other.

"I don't even want him to come to me anymore"said Deni, breaking the silence, a somewhat random thought escaping her lips,"but I can't not let him ”.

"I know love, I understand"I said, trying my best to be see, not that I could stand the cerebration of him fucking her either.

"and we're going to have a infant ”, she added,"I'm so happy it's your babe and not his"

I kissed her lovingly, holding her tight to me and she kissed me back, a tear running down her impertinence, soaking into the pillow.

Our age dispute no longer seemed a concern, we were just two the great unwashed in love.

"set up for your next lesson ?"I said light-heartedly, trying to detract her from endlessly dwelling on the challenges that lay ahead of us. She punched my chest playfully as if to cue me of how out or keeping and flippant I was being about the earnestness of our situation.

"clock time for your morning masturbation ”, I said, cajoling her and ignoring her protestation.

She looked at me as if to say"are you unplayful ?"

To affirm just how serious I was, I lowered my head and sucked her nipple into my oral fissure and nipped it playfully, feeling it instantly harden. Her resistance instantly faded, and she whimpered as I started to suckle, alternating between her nipples.

'' Hmm you bad man '', she responded, as her hand went to her pussy started to play.

I backed away and watched as she grew increasingly aroused. It seemed like such an inherently feminine, yet privileged consequence that allowed the peeper inside me to ascertain such an intimate act. I allowed her to carry on for a few minutes, before I interrupted her.

"Not like that… go over so you're face down and work your knees up so that your ass is in the air, but don't stop"

She looked at me curiously but silently complied, rolling onto her tummy, her cute little burp butt exposed to the light. She continued playing and her whimpers turned to moaning as her fingers flicked and stroked her clit. Her pussy started getting wet, glistening in the low morning sunlight that was streaming through the drapes. I rummaged in my bag of plaything and brought out the small bottleful of lube, trickling a drop from the fissure of her ass and observance as it made its way down between her cheeks, over her puckered anus and onward to her pussy.

I placed both handwriting on her ass cheeks, separating them, and I watched as her fingers busied themselves, stimulating her clitoris. Rubbing my midsection finger into the lubricating substance, i swirled it around her anus.

At the low gear touch, she flinched, clenching her cheeks together."no, not there, not there, that's not ripe"she protested

"relax honey, I won't injury you, just relax and let me teach you something"

It took a few instant but eventually she relaxed again, and her fingerbreadth busied themselves on her clit, occasionally slipping inside her pussycat. She was again, sopping wet and I knew from her breathing that it wouldn't be too long before she orgasmed.

I circled her sphincter with my finger, lubricating it, and then pressed the tip of my finger just inside, holding it there. Her piffling anus twitched and tightened against my fingertip, trying to kick out it, but I held it there, rubbing gently. Her groan grew louder and her fingers worked more frantically to fucking herself. I pushed further and my fingerbreadth slipped inside, pressing down onto the membrane that connected to her cunt. Gradually, I started to ease the finger out and back in, slowly fucking her with it.

Satisfied that her anus was now lubricated and a little more relaxed, I took grip of her vibrator and trickled some more lube on it, before turning it on low and inserting the tip into her dark small entrance. Deni arched her back, moaning loudly, and still her fingers worked on her pussy. Just as I sensed that she was near to climax, I pushed the vibrator a few inches inside."holy fuck"she screamed out and instantly exploded in a frenzied orgasm, her succus spraying from her, streaming out and wetting the bed. Her all body shook.

I withdrew the vibrator, turned it off and leaned over her, whispering"lesson turn 3"

She rolled onto her back, heaving, gazing at me with that same startled flavor, like the look she gave me the very first meter I ever fucked her. She lay there like a quivering mess, her eyes blinking.

"Dam you, you made me wet the bed"she said, after she calmed down.

"ok my love '', she said `` your spell ... I want to watch you masturbate"

Her request shocked me. I mean I would often wank at home alone, but I had never masturbated in battlefront of another cleaning woman. I persuaded myself that I had no choice, I had expected her to comply and she no doubt expected me to set an instance. Reluctantly I lay on my back and taking my already throbbing putz in my justly script, started to pump it. My memories filled with the sight of her beautiful, aphrodisiacal body, of the night when I first fucked her next to the comatose body of her sleeping husband, imagining things I had not yet dared try with her.

Deni, being curious got up close, watching as I pumped my cock furiously. Her innocence enthralled me, and I felt my lump tightening, the visions in my head becoming more extreme, my heart racing, and suddenly my tool erupted. The initiatory current of cum took her by over surprisal, blasting her in her brass, the secondly blasting into her hair. As she flinched backwards, the third dabbled across her mammilla. Recovering herself, she dived onto my hammer, taking it into her mouth, sucking out any remaining cum.

"That was freaking awesome"she said, grinning as she backed off my slightly deflating cock.

Deni looked a characterisation, cum splattered everywhere on her, running down her nerve, over her back talk and dripping from her chin.

We both laughed, and wrapped ourselves in each other's arms. I kissed her lovingly, my clapper tasting some of the cum still remaining in her mouth.

"Gary honey, I wish I could remain, but I really require to get ready for work… I have class today"

I understood that all in effect affair needed to fall to an end and so we both headed to the can to shower together. We towelled dry and Deni took a hair dryer from her drawer to finish off. She grabbed a low, bolster bra from her underwear lot and pulled on a pair of brisk panties. She added a white button-down blouse and a wickedness skirt, making her seem so professional and so much older than she was.

"wait, I have something for you"I said, reaching for the bag of sex toys.

"You'd better fill that with you, I don't want Dave finding some unexpected surprises when he comes home"

I laughed and took out a distich of duo-balls, the two golf game lump sized spheres that wobble when you move. I reached under Deni's skirt, sliding my hand inside her panties, and pushed the clump bass inside her with my fingers.

She didn't resist but instead, asked"What are you doing… what are they ?"

"hold those inside you all day ”, they'll remind you of me.

"Silly man, how can I forget you ?"

"Remember, don't take them out for any reason… hope"

"ok I promise"she said, her locution still puzzled

We went down to the kitchen and sat drinking coffee

"I love you Gary Stevenson ”, she said, staring at me with love-filled eyes

"I love you too ”, I responded as if our lovemaking was the most rude emotion, unhindered by the world of our circumstances.

She smiled happily, like a young girl given a new pony.

As we both headed for the social movement door, I pulled her to me and kissed her deeply.

She set off for work, her car disappearing down the street as I let myself back into my house. I guessed that I should make an effort to work too.

The dawn progressed and I responded to a couple of calls left on voicemail yesterday. They were a bit unhappy, but in the end, I fixed their problems and gave them a hefty discount rate for the inconvenience ; a price well worth it for my day and nighttime with Deni. I was in love and the day somehow seemed lighter, brighter than before.

Just after luncheon, my headphone buzzed as a text edition message came through."Dam it Gary, I'm as horny as netherworld ”, I grinned and wondered just how wet her panties were. The telephone buzzed again"I love you, can't stop thinking about you ”.

I texted back"I love you too"... I knew we were heading for trouble.

As much as I wanted Demi for myself, I was determined to try not to make more fuss for her and her married man. It was bad enough that she was carrying my baby, but now we were both in love and I had no idea how to hold back this. Deni would text me at every luck she got, just short-change substance of"I love you ”,"I need you"and such. I couldn't assistant but love her, she was behaving like a teen in a outset relationship. I guess in a way, we both were.

It got to almost 4pm and my earphone buzzed once again. The message read"Dave messaged me, he's stopping away one more night ”. My warmness raced at the prospect.

I heard the sound of her car pulling up about 5:30, right at her usual time, but instead of heading home to her family, she rang my buzzer. I opened the door and she literally leapt onto me, wrapping her arms and branch around me, her chick rucked up to her shank, and kissing me deeply, her tongue immediately searching for mine."I love you so much Gary Stevenson"she blurted out, kissing me again. I couldn't resist if I tried and kissed her right field rear. I adored her just as often as she adored me.

I kicked the threshold closed and pushed her back up against the hallway bulwark. She tugged at the fastener on my pants, and I pushed my hand up her skirt. Her panties were sopping wet. I fished around inside and found the small string that attached to the 2 balls inside her pussy. She was insatiably on fire and having successfully unzipped my gasp, I felt them fall to the storey. My stopcock already standing to care popped out of my boxers. I shoved her panties to the face and holding her coffin nail in both hands, pressed my putz effortlessly into her well greased twat, humping her against the wall. She literally howled like a fair sex possessed, a woman possessed with both love and lust. Her nipples hardened so lots that even the extra padding and confines of her bra couldn't prevent them from tenting through her blouse. I fucked her hard and fast, feeling one orgasm after another edifice and releasing like waves crashing onto a beach. By her third orgasm I couldn't bind back and released deep inside her. The intensity of my own orgasm was so inviolable that my legs felt weak and I struggled to not birth them have way, holding her tightly against me so I wouldn't fall her. We kissed again as I pulled out of her.

"oh my god, I needed you so bad"she purred looking lovingly into my eyes."Those balls are so unfair, I've been horny all day and almost came in course ”.

I grinned, having known before I used them, how they would create her feel.

"I'm starving… you ?"she asked, finally sliding her metrical unit to the floor a relieved and fulfill expression on her face. I had to take that I was feeling hungry too.

"Why don't we eat out ?"

I knew of a courteous eatery in the downtown district, nowhere near our neighborhood and reassured her that it would be fairly good to go there. She nodded her agreement.

"I better go home and change ”, she said

I chuckled,"no need sweetie, you're lovely as you are"

She raised an eyebrow but resigned herself to sitting there in cum-filled step-in

We had a pleasant and placidity romantic dinner together, a candle-lit windowpane table overlooking the city and even had a chalk of wine with the meal. To anyone who saw us, we would have appeared to be a perfectly happy and formula couple.

After returning habitation, we headed back to Deni's house again. She changed out of her piece of work clothes and put on an old, oversized T-shirt. We then cuddled together on the lounge and settled down to watch a movie together, Deni sitting across my lap, her left shoulder tucked into mine and her pes stretched out along the sofa, as I held my arm around her.

"This is all I've ever wanted"she said, snuggling in more.

At one point during the movie, Dave again called. Although I couldn't hear his side of the conversation, I could tell from her response that he was being a little more inquisitive about her night at the film, who she went with, and where she went to watch it. Deni continued to maintain her exculpation that it was another one of the instructor and that they had only gone to the local anaesthetic motion picture dramaturgy. I could tell from her tincture that she started to get irritated with him. She hung up on him and tossed her phone on the couch, turning her nous to buss me. I decided to stay out of the conversation and just kissed her back ; her backtalk were always so diffuse and delicate.

Our kinship was evolving, no longer just about lust, although I still got hard whenever she was around me, yet it was taking on a different accent ; just getting to lie with each other and learning to be comfortable together. Later we retired to bed together, first showering together, where we hugged and kissed under the fond spray.

Deni slid to her knees and without any prompting, took my shaft into her warm, wet, mouth, sucking and licking it as if she had been doing it forever, her right script between her legs to play with herself. I let her suck me for several minutes, the tone of her rima oris around my cock was incredible, velvety, gentle, warm, titillating, but before it went too far, I stopped her. She looked at me with pleading optic, hungry to delight me, athirst for her own discharge but I held off, wanting instead to make the most of it in bed with her.

After toweling dry, we climbed into bed and started to kiss and explore. I was hard in no time and again, Deni was learning fast and took the initiative, climbing on top of me, sinking her pussy down the duration of my shaft and riding me, my hands massaging her perky little tits, toying with her pap. I reached into her bedside drawer, where she had stashed her vibrator and the bottle of lubricating substance, trickling a generous amount over the tip. She looked down at what I was doing as she bounced up and down, whimpering each time she sank onto my cock, oddment clearly in her eyes. I pulled her down so that her titmouse pressed into my chest, her hips still busy pumping up and down, and trickled some lube down the chap of her ass.

I turned the vibrator on and slid it down her lube face until I found her tightly closed sphincter muscle ; she gasped, staring at me blanket eyed, as it made contact with her sensitive little opening. I moved it in a twisting circular motion, stimulating her, occasionally dipping the narrow-minded tip just inside, her musculus yielding slightly each meter. I could feel the oscillation through the tightly stretched rampart of her twat that gripped me so tightly. Each time I penetrated her, Deni's eyes would close and her mouth would gasp open a niggling. I pushed further, sliding an in of the vibrator into her ass and she moaned deeply, a shudder running through her torso. As she lifted her hips on her upward slash, I pushed the vibrator almost fully into her and held it in place, causing a prolonged lament as she sank onto me again. I almost erupted into her, the sensations of her soft silky walls vibrating gripping my turncock like a vice, the vibrator in her ass intensifying the pressure, but using immense self-control I forced myself to center and not bring out just yet. I started to do it her with the vibrator, Deni was becoming more liven and vocal with each poke, at times burying both deep inside her. here and now later, she lost it completely, screaming as an intense climax frantically shook her eubstance, her pussy gripped me hard, succus squirting over my abdomen, before collapsing onto me, a breathless, whimpering mountain. I removed the vibrator, her anus squeezing it out.

I let her convalesce for a few consequence and then rolled her off me, instructing her to kneel face down and I placed a pillow under her pelvis. I straddled her from tooshie and lined the tip of my cock with her little rosebud, which still had not fully closed. I pushed forward firmly and she yelped in pain.

"trust me, relax your muscles, let this find"

"too big, too big"she shrieked, trying to clamber away as the head stretched her open,

I pressed harder and she shrieked, flinching as the head slipped inside. I felt her tensing and I knew it must have been abominable, but I wanted her to experience it. I waited a present moment for her muscles to adjust to the girth of my invading tool and then pushed forward again, sliding a little deeper into her. Although her pussy was still incredibly tight, her anus was without doubtfulness the tightest grip I had ever felt. I drove another column inch into her, repeatedly pulling back before pushing forward again, inching my cock into her ass. Finally, I bottomed out and started to rhythmically fuck her. She was trembling but her cries of pain sensation were transforming into a deep guttural moaning, her hips starting to respond, meeting the pattern of my throw. As her ass adjusted to me, I picked up the footstep to increasing call of"oh my god, oh my god"and she screamed and exploded into an orgasm, her ass clamping like a vice around me making me lose any semblance of self-denial, my mind went blank as my balls erupting forcefully, shooting endless rophy of cum inside her.

I was drained, and collapsed onto her, taking my weight on my forearms, taking a few consequence to see my breathing time, my tool still buried deep inside her. Eventually, I slipped out of her and rolled off onto my back and she snuggled into me, kissing my boldness and neck.

"I never knew, I just never knew"she said, eventually.

I looked at her and kissed her

"I'm sorry if it hurt you… it will get wanton ”, I said, trying to reassure her.

We lay there for various second more, letting her process what had just happened and then I spoke to her again.

"You seemed to enjoy having both of your hole filled"

Deni flushed red and averted her eyes as if in shame.

"Did you ?"I asked

She hesitated but eventually a soft"Yes"came from her.

I smiled

"Have you ever fantasized about having more than one guy at a time ?"I asked, mostly out of a kinky signified of curiosity.

I had never thought seriously to share her, it was bad enough that she had to continue wed to her husband, but her reception to being fucked, while at the Same clock time having a vibrator in her ass, awakened my interest.

"Noooo, I just want you, you're all I ever need"she replied

I smiled at her, holding her and kissing her.

"Have you ever watched Porn ? ”, I asked

She shook her head,"no, never ”. She was so innocent and naïve about the Earth of sex but I was enjoying watching her grow.

"Do you feature a lap-top ?"

"Yeah, ‘ course I do"she replied

"Go get it"I said

She climbed out of bed bare and padded out the bedroom, returning a few minute of arc later with her laptop. She climbed into bed with me again.

"act it on and let me consume it, I want to show you some videos"

Once she had got it running, I raised my knees and placed it on my lap, navigating to a web site that I had often used. I ***********ed a television, wrapped my arm around Deni and she snuggled into me so that we could check together.

The short video extract showed 2 men undressing a miss and then making out with her, which quickly led to a aspect of her sucking each guy in turn. The scene soon evolved into a panorama where the girl had one guy in each gob as they both fucked her.

Dani watched intently, and I noticed in the cause of the bed covers that she was already playing with herself. She was getting extremely aroused again, trembling in my arms as she experienced a minuscule but discernable orgasm as the 5-minute video concluded by the girl receiving two cream-pies.

The succeeding video showed several men fucking a young woman, sometimes individually and sometimes collectively. One of the cat repositioned her back laying across a bed, her question suspension over the edge, with the guy pushing a long putz deep into her throat, while another took up position between her peg and fucked her.

Her bridge player was once again quickly bobbing up and down under the weather sheet, but her expression seemed quite shocked.

"oh my god, that looks so shuddery"she said

"Yeah, that's quite a challenging thing to get used to, it takes praxis, but guys love it"

"would you look me to do that ?"she asked, nervously

"I'm a guy, aren't I ?"I said rhetorically.

She pondered my reaction, yet kept her eyes glued to the unfolding panorama. The guy fucking here face appeared to stiffen and discharge down the lady friend's pharynx, while the former gave her another ointment pie. I was used to these videos, they seemed so represent and on their own, would not normally have aroused me but watching Deni's innocent reaction to them was the biggest turn-on for me. Another guy took his place between the girl's legs and again started humping away.

I watched as Deni continued to stare at the screen, riveted to the unfolding vista, her handwriting now working frantically on her puss, biting her bottom lip. here and now later, she cried out as a large orgasm hit her.

I closed the lap-top, climbed between her branch, and worked my putz into her extremely wet pussy. I fucked her backbreaking, and she wrapped her legs around the minor of my back, panting, her center staring straight into mine and I quickly elicited yet another orgasm from her before dumping my seed into her puss. We were both spent, and I rolled her onto her side so that I could smooch with her, my cock still inside her, my arm around cupping one of her low chest. I kissed the spine of her neck and we drifted off to sleep.

I woke first, it was betimes, and I turned over to look at Deni. She was on her English, sleeping, facing away from me in pretty very much the same position as when she had fallen asleep. I adored her body, her dark still pelt, her slender build, she was every bit a perfect little angel and so sensual. She was totally wasted on her useless husband and I was totally in erotic love with her.

She must have sensed that I was staring at her, as she stirred and rolled over to look at me.

"dear morning, sleepyhead"I said as her smile illuminated, finding me in bed next to her.

She smiled, blinking at the daylight, while stretching and rubbing the slumber from her middle with the rear of her hired hand. I leaned over and kissed her on the lip, my fingers tracing down along her slit and acting with her clitoris. She sighed softly, voluntarily parting her wooden leg for me.

Your turn, I said, taking her hand and placing it on her pussy. I want you to do this every morning without fail.

"every morning ?"

"Yes ”, I emphasized, grinning

"What about my husband ? ... I mean… he might see"

"He may well savour seeing you do that too, but we'll talk about that later, for now I just want you to promise to do that every dark and every good morning"

"ok, I promise"she replied.

She smiled happily as she leaned forwards and sucked my hammer into her oral cavity, carefully stretching around it so as not to scratch as she bobbed up and down, all the clip, her fingers starting to arouse her pussy. Her velvety tongue felt heavenly as it swirled around his head and scape. I allowed her to continue until I felt her getting close to an orgasm and then eased my stopcock out from between her rim, climbing off the bed before twisting her body around until she was laying with her head off the end of the bed. She looked up at me nervously, no uncertainty fully mindful now of what I was planning to do.

I supported her fountainhead in both manus and skid my engorged peter back into her mouth, this time taking control of how deep I went. I moved my rosehip forward, sliding my cock in over her tongue. Her hired hand had stopped playing and she was reaching for my irradiation as if to keep in line it.

"keep performing, lease your hand away"

She was trembling, scared of what was coming.

"Try to relax love, I won't hurt you ”, I tried to reassure her, but she continued to tremble.

She gagged and started salivating, as the tip of my stopcock caught the back of her throat, so I withdrew slightly and giving her a here and now to recover, pushed forward again. This occurred several times over the next minute each time my cock touched the sensitive character of her lip. My rooster was already big for her mouth and she had bother getting her oral cavity open wide enough. I eased forward again, this time pushing more assertively, my dick found the curtain raising to her throat. She coughed and started to panic, so again I withdrew slightly. Meanwhile her fingers were working in a frenzy on her clitoris.

I started speaking to her in a reassuring timbre"Take your judgement off what I am doing honey, try to completely decompress, try to imagine you were that young woman in the picture with a guy fucking her throat, while others fucked her pussy… imagine you are her… trust me, I won't suffering you ”.

She murmured something that I could barely make out but seemed to swallow as she closed her eyes and go under her fingers into her pussy. I eased my hip joint forward again, holding her capitulum still. I felt the entering to her throat and pushed hard, her throat resisted, so I pushed harder, and my cock forced its way against the density of her throat muscles, inching deep interior. She was gagging and attempting to cough, but my prick was blocking her pipe as I pushed even further. Her cervix bulged and I felt the vice-like grip of her throat around it. I pushed harder until her sass was right wing up against my egg. The sensation of being in her virgin throat was incredible and I couldn't hold back more. I unleashed a violent stream of cum straight into the piping that led to her stomach. Holding there a few seconds more until my turncock had finished pulsating, I withdrew. Deni had a coughing fit middle gasping for air, making crying in her eyes and saliva poured from her mouth. My cock was soaked.

I pulled her head up, taking her berm and maneuvered her into a sitting emplacement. I wrapped my arms around her and hugged her tightly. For a maiden experience, she had done extremely well.

"Did I do ok ?"she asked, tears still in her eyes

"You did wonderfully my little angel"

Despite her tears and coughing, she had a self-satisfied look on her face.

"Now how about finishing off your own orgasm"

She lay back, eyes closed, and frantically fingered her purulent"

I lay down following to her and whispered into her hear, my finger slowly circling her protruding pap"Imagine I'm fucking you and other cat are naked, stroking themselves, waiting to bear their turn with you… imagine you are the center of attending and making them all horny just like the television"

Deni started whimpering and moaning, lost in her own little mankind, her fingerbreadth making a squelching auditory sensation as they worked in and out of her twat. I wished I had the stamina to keep up with her, but after cumming just a few minute earlier, I knew there was no way I could go back my stamen before she had once more to leave for work.

She worked at her kitty-cat for several Thomas More minutes before crying out, her belly rippling as her coming finally broke over her.

I kissed her deeply and she responded, kissing me back lovingly.

We rested for several minutes, holding her in my arms, until she literally had to get up for work. She dashed to the bathroom for a pee, washed her face and brushed her teeth, before returning to the bedchamber. I lay in bed watching her naked body as she rummaged in her drawer for fresh pair of panties and a bra. I stopped her.

"Deni, from now on, I don't want you to get into panties… I think you'll find it incredibly sexy"

She turned and looked at me aghast,"you got ta be kidding me"she said somewhat abruptly.

"Just try it for me"

"I love you ; I'll do anything for you, but oh my god, what if someone sees ?"

Her boldness slightly forlorn but resigned to trying what I had asked her to do. I wasn't too serious initially, but the kinky side of me saw it as quite aphrodisiac."and no more bras unless you're going to act upon ”. I had to give her that conceding as I didn't want her to get into trouble at the school.

"ok honey ”, she replied, accepting the idea, albeit reluctantly.

She pulled on her skirt up over her bare kitty, fastened her bra behind her and withdrew a plumb blouse from the closet.

She finished dressing and gave me a fragile twirl."do I calculate ok ?"she asked.

"Very fuckable ”, I said. She blushed and giggled, still somewhat mortified. Her skirt was quite pixilated over her slight bubble but and it was clear, at least to me, that there was no outline of any panties.

"I have to go soon"she said despondently,"I wish we could have more dark together, but Dave is home tonight"

"I got out of bed, naked, and hugged her, kissing her softly as I held her to me"

"I love you Deni, to a greater extent than you can imagine ”. She smiled happily and as she kissed me, I could see the erotic love in her eyes.

"I really make love you Gary, but I feel weird about Dave now… I mean I really don't want him to touch me anymore"

"Deni, sweetheart, I know you don't but if you suddenly block off having sex with him, he'll get suspicious and we don't want that, so we may as well try to come up a way for you to enjoy it at least… and this way, you know you're doing it for me"

I dressed and we went downstairs for coffee. I loved the idea that she was raw under her black-tie dame and wondered about how Dave would respond to her. We kissed as Dani readied herself to leave and I made my way back home. I was torn between loving her, wanting her as my own, and enjoying how her sexuality was developing.

Moments after returning home, I heard her car driving force away .
