Sexy Fun Times/Work/Doctor/Sophie & Mom/Sophie/Slow

After a series of texts you are expecting twelve-year-old Sophie, who is supposed to be going home after school. Given her inexperience, you decided not to answer the door in a robe, so you are wearing slacks and a shirt, with bare feet when she knocks.

Sophie is a little on the chubby side, but she has a pretty face and her nervous smile reveals braces over her white teeth. Her uniform skirt is pulled up as short as possible revealing a good deal of tanned thigh above the white socks. Not for the first time, you speculate that the men who design school uniforms must be as perverted as you are.

"I told Mum that I was auditioning for the school play," she says. "Actually they did it last period.

"What's the play?"

"Oh! Err, Romeo and Juliette."

You think for a moment and strike a pose. "What's in a name? that which we call a rose. By any other name would smell as sweet.”

It takes her a moment to come back with a reply. “Romeo, Romeo, wherefore art thou Romeo?”

You both burst out laughing and she flops down on the couch. You fetch her a drink - Coke with a measure of vodka in it and loads of ice. You sit in the chair opposite her. "So, are you Juliette?"

She takes a drink and shakes her head. "Melanie has that sewn up. I'll probably end up moving scenery or something."

"Aww, I think you'd make a great Juliette. She was your age you know."

Sophie giggles and takes another drink. She has her feet tucked under her and her skirt has ridden right up to reveal a pair of white panties stretched over her pussy. "I'd have thought that Lolita would be more your kind of thing," she says.

"Ah! Yes, she was your age too, maybe a little younger. She led poor old Humbert a bit of a dance though."

"Touring around America in those days must have been fun though. And no one queried a man sharing a room with his twelve year old niece." She puts her drink down, stands up and walks over to you. "Are we going to discuss literature, or did you have something else in mind," she says, climbing onto your lap.

She wraps her arms around your neck and pulls you in for a kiss. She may only have had sex once, well twice now, but she is fairly experienced at kissing. Her lips are soft and as soon as they are pressed against yours, you feel her tongue exploring. When you both come up for air, she slips off and stands in front of you. "Put some music on," she orders.

It take a couple of tracks before she finds one she likes and then she starts to bump and grind, swiveling her hips as she undoes the buttons at the front of her shirt. As she reaches behind to unhook her bra, she explains that it's not for support, but because her nipples get sore, rubbing on her shirt.

She cups her hands under her small breasts and pushes them up. "Do you like them," she says, licking her lips.

You nod. "Very much."

Her skirt has a hook at the waist and a zip on one side. She has to suck her belly in to free the hook and then she drops it on the floor, steps out of it and kicks it to one side. Now she stands up straight, wearing just her panties and her socks. You are sitting with your legs spread apart and she watches as you unbuckle your belt, pull your fly down and free your stiff cock.

"It's even bigger than I remembered," she says, licking her lips again.

"It's not porn-star sized, but a bit more than average," you say.
