Older sister Liz

"Fucking pervert!" Liz shouts from the door. Judy screams from the next room and you turn to see her jump out of bed. She runs, naked, to the bathroom door and throws it open, and her mouth drops as she sees you, tiny bathrobe hanging open and bulging cock standing straight out. She must be pretty surprised because she doesn't move an inch, even to cover up.

Liz seems to notice Judy and a huge smile spreads across her face. "Oh, I see," she says. "Becky's boyfriend was getting a little show." You and Judy both start to blush furiously. Judy slams her door in your face, and you start to close your robe.

But it seems Liz has other ideas. She steps into the bathroom and closes the door behind her. There's not much space, and her tall, lithe form stands very close to your exposed body.

"Not so fast," she says. She grabs the robe and forces it back open. You're too shocked and ashamed to resist. Liz is looking you over; you're trying not to make eye contact.

"You're in trouble, pervert," she says. "But we're going to have a little fun with this," she adds, a gleam in her eye.

"I can leave you here and move on. But then I'm going to tell our parents what happened, and that will not be good for you. Or Becky for that matter.

"Or I bring you in to Judy so she can decide what happens to you for spying on her.

"Or you come to _my _room so I can punish you."

You're obviously not going to let Liz ruin the rest of your life by tattling on you to her parents. So which girl are you going to submit to - the busty younger sister or the dominating older one?
