Yes, and it's Jack, Stacy's boyfriend

"Hey sweetie, is that you in there?" you hear the voice call out as the door opens, but you can tell it does not belong to your boyfriend. Only when you see the guy's head peek in can you tell who it is. "Jack, what are you doing!?"

Your surprise startles him and he quickly adverts his eyes. Good thing too, since you are already stark naked and soaking wet. "Oh, shit. I'm sorry John. I was looking for Stacy. Have you seen her?"

You shake your head. You had not seen her since the start of the party. "No, sorry. Is it important?"

"No, I was just looking for her." But you can tell something is wrong. He looked like he was either angry or just upset. They must have been fighting. You could see why, of course. Stacy was always a bit of a bitch, as much as you loved her.

"You're lying. Why don't you come in and we can talk," you say, reaching out of the shower and grabbing a towel, wrapping it around your body and tucking the edge between your park breasts.

He took a seat and started to spill his guts. "She was flirting with some guy and I called her on it. We yelled a bit and she stormed off. I can't believe this. I hate it when she drinks. Not like she would cheat but she knows it makes me so angry when she does not."

You nod along, leaning back against the sink counter just across from him. You know how Stacy can be. Before either of you had boyfriends, she was always the one that fooled around the most. A bit of a slut, really. You did not think she was the cheating type either, but then again, anything was possible. It's not like neither of you had never talked about the possibility of going behind your boyfriends' backs. But that was just idle girl talk, right? Either way, you kind of felt bad for the guy and wanted to help him.
