Go to his room

Okay." you agree shyly.

Once in his room he seats you on the bed and begins undressing. You watch, growing more aroused as he reveals more bare flesh until he is finally completely naked. You can see now that he is also growing hard.

"Do you want a taste?" he asks, holding his penis to make it clear what he means.

You nod and move to your knees in front of him. Licking along its length you make it grow fully erect then take it into your mouth. You move your head back and fourth as you move your tongue across the head. You're clearly doing a good job because he begins to breath heavily and move his hips with the motion of your lips.

Eventually his penis begins you pulsate and squirt into your mouth. With him still filling you mouth you can't spit out the semen. Although some of it dribbles down your chin, you end up swallowing most of it.

Satisfied, he withdraws from your mouth and helps you up. He kisses you passionately, apparently unconcerned by the semen still on your lips. Then he lays on the bed with you. For a moment you worry that he is going to leave you unsatisfied but he slides his hand into the leg hole of your diaper and caresses your balls for a moment before taking hold of your penis. He moves his hand up and down the shaft, first slow but soon increasing speed and before long you begin ejaculating into the padding between your legs.

He keeps rubbing until you are completely done then he gets up.

"Where are you going?" you ask, breathlessly.

"I'm going to get you a clean diaper." he explains. He opens his wardrobe and takes out another diaper and a package of baby wipes. After unfastening the tapes and pulling your diaper open he begins cleaning you. If feels cold against your skin, especially after the warmth of the diaper, but not unpleasant. He rolls up the old diaper and used wipes then unfolds the new diaper and slides it under your bottom before sealing you into it.

Stephen turns off the lights and once more joins you in bed. Moving his body up against yours he hugs you tightly.

Before either of you have had a chance to fall asleep you begin to feel the increasing need to pee. You move to get up.

"Where are you going?" Stephen asks, sleepily.

"I have to use the toilet." you inform him.

"Just go in your diaper." he says. "I'll change you in the morning."

"You want me to use my diapers?" you ask.

"That's what they are for." he says.
