Explicit Proposal

Leaning back on his haunches, sitting on his heels, Marc's giant erection pointed straight out and swayed heavily to and fro between his legs. I still couldn't believe the size of it! Jen is a rather petite woman, with a smallish slit to match. I doubted she would ever be able to accommodate him and I was concerned that he would hurt her. My wife on the other hand, couldn't take her eyes OFF it. The expression on her face combined wide-eyed awe with insatiable lust. Marc grabbed a tube of KY jelly off the night table and applied a generous amount along the length of his penis, working it in as he stroked his impressive man-meat back to full size. My wife looked on silently as he did so, biting her bottom lip in anticipation. Marc was soon poised and ready to enter her - the coup de gras.

"Nice and slow, okay Marc?" pleaded my wife. "You're twice the size of my husband. I've never even SEEN one that big before!"

I gulped when I heard her say the words, momentarily rattled by another wave of jealousy.

Like a thin edge of a wedge, he pressed the tip of his cock's huge head against her opening, forcing the lips of her vagina to open wide as he slowly made his way in. She craned her neck so she could watch as inch after inch disappeared inside her; her breathing became short and fast.

"Oh Marc, it's so BIG!" she moaned.

She topped out with only a few inches to go and her poor little sheath looked stuffed and stretched to the bursting point! Marc was obviously reaching places inside her that no man had touched before. After she'd maxed out, he slowly withdrew before forcing his way back in all over again. He kept this up, always increasing the pace of his thrusts until his over-sized engine of pleasure was pumping in and out of her like some huge fleshy piston running at full tilt. Her moans became whimpers and it was hard to tell how much was pleasure and how much was pain - though it was obviously much more the former than the latter.

"OH MY GOD, MARC!!!" she panted loudly. "IT'S SO BIG!!!"

Jen reached down with a finger, and, without interfering with his full frontal assault on her beleaguered pussy, intensified her pleasure by simultaneously massaging her clit. The incredible tandem of vaginal and clitoral pleasure quickly sent her soaring off into the throes of another euphoric orgasm. Her moans became incredibly loud. My studly neighbour was obviously quite the cocksman - and Jen apparently a proponent of the 'size matters' contingent of women.

Marc directed her to turn over so he could fuck her from behind. He inserted the head of his giant penis back into her dilated tunnel and placed his large hands on her gorgeous, curvy ass. Jen, still breathless, flung the pillows off the bed and braced herself against the headboard. Try as she might, Jen could still not take him all the way - his nine plus inches were just too big to fit.

Watching my wife play out a lead role in this impromptu pornographic video was making me dizzy. I kept pumping my own, mortal-sized hard-on and indulging my voyeuristic tendencies while Jen got royally fucked by a hunk of a man with the biggest cock I'd ever seen. I found it impossible - even pointless at that point - to reconcile the myriad emotions I was feeling: jealousy, guilt, excitement, and desire.

Marc quickly regained his previously relentless pace, tightening his ass and bucking his hips as he thrust his massive penis in and out of her at ramming speed.

"OH, MY GAAAWWD!!!" gasped Jen. "OH MY GGAAAWWD, MARC!!! IT'S SO BIG!!!"

"You like my big dick, sweetheart?" taunted Marc, no doubt as much for MY reaction as hers. "You like it better than your husband's little one?"

"Yes! Oh God, YES!!" she answered breathlessly. "I love your huge cock! You feel fantastic! Fuck me with your big dick, honey. FUCK ME!!!

His staying power was mind-boggling. But finally, after what seemed like an eternity, Marc announced that he was ready to relinquish his seed.

"Oh baby, I wanna taste you!" said Jen as she whirled around and grabbed his big stick with both hands.

She gave it a few final pumps as Marc's scrotal sac tightened. My wife parted her sensuous lips just as gobs of white cum shot out of the tip of her lover's penis, splashing against the back of her throat. Once again, she stuffed her mouth with the engorged head, swallowing as much as she could of his copious ejaculate. She milked his enormous stalk with her fists; streams of excess semen trickling down the length of his cock and over her hands. She let go of his spent weapon and rubbed the remnants of his orgasm into her enormous breasts. Seconds later, and with impeccable timing, I experienced an incredibly intense orgasm of my own.

The two of them lay together on the bed for several minutes, kissing and touching each other tenderly, before Jen got up to take a shower. Marc took advantage of her absence to reach for the remote and end the tape - grinning at the camera as a last image.

To make a long story short, I honoured my part of the bet. I packed a bag and checked into a hotel downtown - telling Jen that I would be out of town for a week 'on business'. According to Marc, the two of them made love repeatedly every day that I was away. He said that it was the best sex he had ever had and that my wife had an incredible sexual appetite.

If there is a positive to this story, it is that, although Jen never found out about the bet between Marc and I, the experience precipitated a more experimental chapter in our sex life together. As a result, we have both enjoyed a more open sexual relationship with each other as well as other couples.
