Cathy's coming

A blur of red comes flying into the room, trailing a damp towel.

"Eek!" Ellen says. Startled, she lets go the dildo and it slides from her pussy with the sound of a little wet kiss.

"Cathy's coming! Hide the menfolk, Ellie," Amy says.

"But it's daytime!" Ellen protests.

"And we're naked and she's at the end of the hall. Under the bed, cowboy."

You squeeze under Ellen's dorm bed. Amy arranges the covers to conceal you.

"What if she looks?" you ask. "You can't just sit there naked side by side whistling Dixie."

"Right, we need a diversion," Amy says. The springs squeak as Amy climbs onto Ellen's bed. "OK Elle, let's let Cathy catch us in the act. Let me point my big ol' butt at the door so I can moon her when she walks in." Amy's weight shifts again.

"What?" Ellen says.

"Do me, Ellen," Amy says. "Do it now, we gotta throw Cathy off. Here, use the dildo."

"Aingh, but that's mine!" Ellen protests. "Oh, all right."

Amy grunts. "That's right, Elle," she says. "Now harder, like you do yourself!"

There are rapid, damp squishing sounds from above. The bed moves above you in tiny, quick motions. Amy groans with pleasure.

The door latch clicks.

"Fuck yeah, Ellen, do me!"

For a long moment, you figure Cathy must be watching from the door, but all you can hear is the wet sounds of the dildo in Amy's pussy and the quick breaths of Amy and Ellen.

"Keep it up, like that, like that, you're gonna make me come!" Amy cries.

There's a throat-clearing sound from the door.

"Go away Cathy, you perv!" Ellen calls, her voice shaking.

"I hate to interrupt, girls, but I think I see something that doesn't belong to you over there," Cathy says.

"Don't stop, Ellen, don't stop!" Amy cries.
