keep quiet and keep fucking

You try to keep as quiet as you can, the ghostly beauty on top of you still rocking around. You can feel your dick still hard inside of her, but then hear your name.
"John? Are you awake? I heard some noises"
"Yeah, I'm still here," you say to Sara. "OK," she says through the door. "I brought you a little snack if you want." You're about to protest and not let her in, but she clicks open the lock and walks in, carrying two plates. "What the hell!?" she shouts.
You look over to where Rebecca was, but she's gone. "errrr, I can explain!" you say to Sara.
