Put on pants and answer the door

The persistent knock on the door helps refocus your mind, and you tear your eyes away from the strangely-erotic sight of your own body. You start toward the door, and then remember that you aren't wearing pants. Quickly grabbing a pair of Zack's jeans, you throw them on, and then, after a quick glance around the room, you open the door.

You see Gwen Elsworth, a fellow freshman who lives in the same dormitory, on a different floor. You have had virtually no interaction with her, but you know that is not true of Zack. You have heard him on more than one occasion update you on the status of his attempts at her seduction. At last report, he appeared to be wearing her down, and Zack hinted that he might be very close to "sealing the deal" with her soon.

Gwen greets you with a smile, saying, "I was afraid you weren't in when you didn't answer. Is everything ok?"

You are momentarily tongue-tied, trying to figure out what Zack would do in a situation like this, and wondering whether it was really a good idea to try to pull this off.

"Uh... sure... it's all good. I was just talking with Zack... I mean, I was talking with Justin....."

Gwen looks over your shoulder and says, "You must have bored him to sleep; it doesn't look like he's much for conversation right now."

"Uh... right... He didn't get a lot of sleep last night."

"You didn't keep him up with some of your all-star feats of sexual prowess, did you? If I believe half of what you tell me, I fully expect to walk in your room and find you've got someone in your bed, waiting for you to get back to her."

It is pretty clear that Gwen wants to enter the room. You're not sure it's such a good idea.
