TVR/Andrew2/Bath

When you get off the bus, Susan blows a goodbye kiss and then wiggles her bum cheekily as she walks off. It's teatime, so you go straight to the kitchen and help yourself to some bread and jam followed by a slice of Mrs Johnson's prize-winning victoria sponge. "I'm sorry about what we did in the pool," Janet says, but her grin says she's not really.

You smile back at her. "Don't worry; I'll get you both back." You finish drinking your milk. "Everything smells of chlorine," you say. "I'm going up for a bath."

There are three bedrooms and a bathroom on the second floor which you and Janet share and you run the taps before going back to your room to undress. With a towel wrapped around your waist, you go back to the bathroom, only to find that Janet's beaten you to it and is already sitting laughing at you in the warm water. You stand there, glaring at her, not knowing what to say and torn between the novelty of looking at her naked body and your annoyance at her having jumped into your bath.

"You could always get in with me," she says with a grin.

You put the lid down and sit on the toilet, aware that your stiff cock is making a tent in the front of your towel. "I'm not sure that's a good idea," you say. "What if Mother came up and caught us?"

Janet shrugs. "She'll be watching TV and Mrs Johnson's gone home.

You stand up and open the front of your towel, revealing your erect cock. "Are you sure you want me in there with this?"

Naturally, you get the tap end and there's quite a lot of giggling as you sort out whose leg goes where. You end up with Janet sitting between your feet and her feet resting on your thighs. "Do you always cum so quick," she asks as she moves one of her feet over to rub it against your cock.

You shake your head. "Sometimes it takes ages, other times it's real quick. It depends what I'm thinking about or looking at I guess."

"We Are Not American," Janet says with a grin. Which is what Mother always says when one of us says "I guess" instead of "I imagine," or "I suppose". "Do you like me doing that that?" She's moved her other foot over and is sliding both feet up and down your shaft.

"I like anything you want to do with me," you say. You lean forward and put your hands on her thighs with your thumbs right up beside her pussy. She spreads her legs apart so you can slide forward and you spread them even further and that you can see the pink inside skin of her pussy. You use your thumb on her clit you can feel her body trembling so you press harder and suddenly her muscles are jumping and she's making funny noises.

"Do you want me to make you cum," she asks when she's got her breath back. "I'll suck you if you like. You get up on your knees and she examines your cock closely, sliding the loose skin back and sloshing some water over it before opening her mouth and allowing you to push it inside. Her lips and tongue immediately do their magic and you put a hand around behind her head so that you can push your cock further in as you feel your balls begin to tense.

You feel her struggling and trying to push you off but you're cumming and your instinct is to ram it in as far as it'll go. When you pull out and sit back on your heels, she's coughing and crying and spitting all the same time. There are tears and snot on her face and she is spitting out spunk. "You nearly choked me," she says after she's washed her face and rinsed her mouth out with the bathwater.

"I'm sorry, I don't know what to say, I didn't mean to push it in that hard."

"It went right into my throat," she says. "I was choking but you kept going.

She's still got tears in her eyes as you stand up and climb out of the bath. "I'm sorry," is all you can say as you walk across the landing to your bedroom.
