You don't have to do anything

You don't see Emily or Liz for the next couple of days. Your friend is almost monosyllabic in text messages and you begin to think that that day of debauchery never happened at all.

Then you get a series of texts:

Hayley come over

Mom and Dad are out

Now

Without giving it much thought you head straight over. Your mind switches between horny (we are just going to go at it) and anxious (she hates me).

The door is unlocked so you just slip right in.

Emily is in the kitchen to greet you. She moves up on you, and kisses you. Any worries you have are gone.

"Hey, so, Jack is upstairs." She says. "He said he would be down for having a foursome with another guy, but only if we had a threesome first."

"Sounds good." You reply.

"I know you said you were up for it." Emily states. "Are you still up for it?"

You nod.

The two of you make your way to her room and Jack is lying, naked, with his eyes closed, on Emily's bed. His cock is pointing straight up, and it looks like he has been jerking it the whole time.
