2T4U/Tiffany/Middle of night/Open Mom's door but then have second thoughts

As you push the door open you feel something wet and slimy between your legs and stop. "If anyone sees, I'll get in trouble," you think.

Just down the hall you hear Aaaron's door closing. This was his fault; maybe you should go talk to him about it. You walk into his room and see that he is hiding under the covers so you trot over, scramble up on to his bed and jump right on top of him.

"OWW!!!" he shouts and his scowling face pops out.

"Serves you right," you reply, pounding him with your little fists.

Aaron easily pushes you off and sits up. "Sorry sis," he says. "I didn't mean to hurt you."

"It didn't hurt... I was surprised and you were rude."

"Sorry... I just... I dunno..."

"What did you stick in me?"

Aaron rolls you off and pushed the covers down to reveal his cock, which is stiff again. You have seen it before, but not like that.

"Why did it get stiff," you ask.

Aaron shrugs. It happens all the time, especially when I rub it. He demonstrates rubbing it.

You watch him and put your own hand between your legs; your pussy is still slippery with his cum. "When I rub mine it feels good, and there's a little bump that gets stiff."

"Did it hurt when I put it in," Aaron asks.

You shake your head. "Not really." Your finger is now plunging in and out of your pussy. "It's not much bigger 'n my finger," you say with a giggle.

Aaron rolls onto his side, looking closely at what you are doing. Having him watch makes it even better somehow. "Do you want to try again," you ask.

He grins. "If you like," he says.

He knows how it's supposed to work, but it's not that easy this time. You lay on your back with him on top and you can feel his stiff peepee poking down, but it's not going in. After a few tries, he gives up and rolls off. "Why don't you try being on top," he says.

You look at him, laying on his back with his stiff little wand in his hand. "Okay..." You sit up astride his legs and look down at it; then you lift yourself up and hitch forward until your right over it. "Ready," you say, and drop down.

"OWW!!!" he shouts. "You squashed me."

This time you go more carefully and with a bit of jiggling around, you finally manage to get it in and you just sit still, feeling it inside you. "You gotta move up and down," he says, so you lift yourself up and drop back down. That feels nice, so you keep doing it.
