REALLY Cheating

Nikki's warm inner thigh was pleasant and moist against my cock. Fuck I was really going to do this. I was going to fuck a woman I'd just met, completely unprotected. The thought brought a rush of blood through my cock, and I adjusted myself, pushing back and allowing my cock to hover a little between her legs.

"I Shouldn't let you..." Nikki gasped, rotating her hips below me. "Fuck... dat feels... "

"Shouldn't let me do this?" I nudged the tip of my cock against the folds of her soft pussy. The feel of her moisture brought a dollop of precum to the tip of my cock, and I could practically feel the soft connection of our fluids as I pulled away again.

Nikki's lips met mine in a hungry kiss as I pushed against her again, allowing my cockhead to run along the length of her dripping pussy. The thought that this was the fourth women I'd been this intimate with in as many days was electrifying, and I pushed down again, enjoying her slow movements beneath me.

"No, I shouldn't..." Nikki breathed out, her hips moving against me. "Ok... just... a little more..."

I pushed my hips forward a little, my cock bumping against her. Damn, wrong angle. She seemed to like it however, especially when my cockhead bumped directly into her clit, and rubbed against it, smearing my precum all over her throbbing little button.

"I shouldn't... want you inside me," Nikki moaned. "My husband will call any second and save me..."

The phone did not ring on cue. I lowered my cock just a little, feeling her inner lips as they spread around the underside of my practically drooling penis.

"Last chance to tell me to stop..." I warned her, knowing what her answer was going to be.

Nikki said nothing, her eyes glued to where my cock was beginning to sink into her body. She seemed to hold her breath as I pushed in, feeling her pussy spreading around my shaft and hugging it tightly. She felt warm and welcoming as I pushed in, allowing her to get used to the feel of me.

"So... fuckkin... BIG..." Nikki panted out, her eyes never leaving where I was delving into her. "OF all the guys... I pick the one..."

A quick motion of my hips burying myself in her deeply silenced her speech with a quick yelp of surprise.

"OH fuck..." Nikki moaned out, her hands flying to my ass. "Fuuuuuck..." She repeated, the word coming out deeply, like it came directly from her diaphragm.

"We're both cheating now..." I grinned in her face, slowly beginning to move my hips against her, and loving how her pussy clutched at me desperately. "Your married pussy's mine now..."

"He was supposed to call... supposed to save me..." NIkki moaned, thrusting back at me slowly. "Shouldn't have left me alone with you..."

"And now your married pussy is all full of my cock..."

"Yes... your fucking cheating bastard cock..."

"Speaking of Bastards..." I thrust against her harder. "You on the pill, my little married slut?"

"I... fuck... no..." Nikki panted at me again, her thrusting becoming more pronounced. I slipped a finger down to rub at her clit as I pumped into her and was rewarded with another moan of pleasure cutting off her comment.

"Not on the pill... with your slutty married pussy all full of a stranger's cock..."

"And I just met him..." Nikki panted. "I'm such a fukkin slut... just like my husband thinks I am...."

"You know... I'm gonna come inside you..." I pumped at her harder. The thought was incredibly wicked and yet incredibly appealing. The thought of her going back to a guy who had completely ignored her when she needed him, full of my seed. It was strangely appealing, and maybe this was just a **** fuck to her, but whatever it was, it was damned hot.

"Oh fuck... dat's like... if you come in me..." Nikki panted. "We... dis is like the worst time..."

"Oh, is that why you're so horny... is it that time of the month?" I purred against her lips, grinding into her again.

"Yeah... when I shouldn't be... fukkin if I don't want..." Nikki convulsed again, and my lips came down on her neck, where I sucked hard. I knew there was no way she could hide THAT from her husband, and it was the reason I did it. Of course she reciprocated, and the feel of my wedding ring crushed against my chest as I pumped at her was a delightful spice to the pleasure.

"Don't want what..." I felt myself growing closer, and my breath coming faster as I looked directly into her eyes.

"If I don't wanna get... pregnant..." Nikki panted at me. "Rhythm method... I know..."

The thought that this was the most dangerous time of the month for her brought a renewed urgency in my thrusts. It seemed almost of it's own accord, a primal urge to mate with this woman running through me. She was here, she was willing, and now my conscious brain was aware of what my body had been trying to tell me since we had met.

She was fertile.

"Oh fuck... oh fuck.. you're... you're... gonna come inside me..." Nikki moaned. "You shouldn't... I'll get pregnant..."

"Better fuck your husband when you see him tomorrow..." I whispered, the feelings of heat beginning to grow in my balls. I could feel the various tensing in my lower body which signaled the approaching orgasm, and I could tell it was going to be a big one.

"Tomorrow..." She whispered. "He'll... surely call... before..."

"Before I knock you up? Better hope he does. Because I think you'd be beautiful with a nice round belly." The feeling of power was amazing. Here she was totally accepting me, and allowing me to totally ravish her. All her husband would have had to do was call her, and she would have flown to his side, I could feel it. There was something **** about the way she was fucking me, like it wasn't about me at all.

"Say it again..." Nikki groaned, her hands now wrapped around me tightly as we humped against each other in the back of the bus.

"What?"

"What you want to do to me..."

"I want to knock you up..." I snarled in her ear before nipping at it. Saying the words seemed to trigger my peak, and I couldn't hold back any longer. My arms encircled her shoulders, and I thrust into her welcoming body as deeply as I could.

I felt the first ripples of her orgasm in time with the first splash of my come as it burst out of me. I saw light circles behind my eyes from the intensity of the orgasm as I pushed into her, feeling another jet of my sperm soak into her.

"Come inside me... makes me... come..." Nikki panted again loudly, and I continued to feel my cock throbbing within her as her moist channel milked my straining erection.

I don't know how long I kept thrusting into her, but it felt like we both came for a lot longer than the orgasm had any right to last. The thought kept running through my head that I was impregnating her right at that moment, and it maintained the sensations.

When I finally came to my senses, I found myself staring into an extremely flushed looking woman's face, and a pair of eyes that simultaneously seemed afraid and turned on.
