Dr. Porter

The person behind the doorway is a woman in her middle age, her wispy greyish-brown hair tied back in a bun. She's got glasses, simple and plain, and she's dressed in a dress shirt and khakis that are tight to her toned body and her breasts. Most of all she seems shocked at what she's found in the office, spluttering silently. This can only be the Dr. Porter to whom this office belongs, seeing as Alaina locked the door when the two of you entered the room.

"What..." she finally manages to say. "What is this?"

Much like the physics professor, you and Alaina are at a loss for words-- and you're still deep inside your floormate, her legs wrapped around your body.

"Uh," Alaina stutters. "You should start locking your door."
