"Could you, um, sit on my penis?"

"So what'll it be, Tommy?" You ask.

You plant butterfly kisses on his cheek and stroke up and down on his condom-wrapped cock. You can feel the nerd's giant pecker throbbing even through the neon pink latex.

"Could you, um, sit on my penis?" Tommy nervously asks as you press your full lips against his face.

"Oh!" You pull back from him with a smile. "I'd love to, Tommy. Do you want me to do it right here on the loveseat?"

He nods. Mrs. Cleft leans over and looks at her son's huge cock and then over at you.

"You can sit facing him or you can sit with your back turned," she explain needlessly. "Tommy, do you want to see her face and her breasts or do you want to see her backside?"

You giggle at Mrs. Cleft's question and stand up. As Tommy weighs his options you do a sexy little pirouette in front of him. You spin and spin, but the poor boy can't seem to make up his mind and you're getting a bit dizzy.

"Put your legs together," you tell Tommy, "and scoot forward a bit."

He does as he's told. You step up to him and turn around. With a leg planted on either side of his knees you squat slowly down. You reach between your legs and take hold of his huge prick. You rub the condom-wrapped head up and down on your well-lubricated slit. The reservoir tip crinkles against your pussy as you drag him back and forth and massage your clit.

"Do you like looking at my ass?" You ask, peeking back over your shoulder.

You wiggle your firm butt from side to side a bit.

"Y-yeah," Tommy stammers, "it's really nice."

"You bet it is," you laugh. "I work hard to keep it that way."

You carefully wedge the very tip of the head of his cock at the parted lips of your pussy. Looking back at him over your arched back you watch his face as you slowly...ever so slowly...slide down around him. His cock is huge, stretching your pussy and causing you to groan and bite your lip as his big plastic-wrapped meat fills your slippery hole. You keep sliding down, taking more of him.

His face contorts with pleasure and he gasps. You've never been so completely filled by a cock. Your thighs touch down on his lap and you settle onto his balls, all nine or ten (or what feels like 20) inches of Tommy's cock buried in your aching pussy.

"Oh my word," you feel slightly out of breath. "Tommy, you're huge."

"God, it feels so good," he moans.

"Mrs. C," you call out to Tommy's mom. "He barely fits! This thing is a monster."

Mrs. Cleft chuckles.

"You'll adjust, sweetie," she pats your butt. "Just take it nice and slow."

You have **** at first. Squatting, impaled on his big dick, you gently rise up the condom-covered length of his cock and then slowly work your way back down. You repeat this several times, each time easier than the last. Slowly you begin to work up to a rhythm. You don't take him all the way each time, instead working the top half of his prick with your tight teenage cunny.

Once you've worked into a very nice groove you start throwing a little wiggle into your down strokes. As his big prick slides into your slippery cunt you roll your hips. You look back and stifle a giggle as Tommy's eyes follow your ass up and down.

"Yeah, you like that?" You moan to Tommy. "You like watching my ass go up and down on that big dick of yours, don't you?"

"Y-yeah," he groans.

"Go ahead," you encourage him. "You can touch my ass."

His unsteady hands settle on the twin globes of your ass as you bounce up and down on his thick totem pole. He squeezes your cheeks in his hands, a bit rough, and you yelp.

"Gently, Thomas," his mother scolds.

He massages your ass more gently as you pop up and down on him. His rubbery shaft presses against your clit with each downward stroke and you can feel your climax building. At the same time you can feel Tommy's cock swelling up inside you. It doesn't seem possible, but it's actually getting bigger as he nears his own orgasm.

"You're doing really good, Joy," Mrs. Cleft comments.

She looks a bit flustered, but you're focused on the huge dick that feels like it's splitting your pussy apart.

"Oh yeah," you moan as your orgasm begins to simmer. "Give me that...give me that big dick. I want to cum on that huge cock, Tommy. I...ahhhh!"

You throw back your head and spear yourself to his base. You roll your hips and grind your ass against him as your orgasm burns through your body. You lean back and rest your head on his shoulder.

"Fuck...I'm cumming," you cry and your pussy explodes in a wild series of spasms.

You ride him with renewed intensity, grinding and bouncing on his prick until you feel like you're going to pass out. His cock is enormous within your fluttering walls and you know he's really close.

You lean forward so he can watch your ass again. Your thigh muscles are shaking and you're covered in sweat, but you're going to give him the best orgasm of his short sex life.

"Are you gonna cum for me, Tommy?" You ask.
