His roommate - and his younger sister

No ****, no NTR coming -- my kinks are around lots of cum and girls losing their minds from pleasure -- sorry if you were looking for shenanigans involving the roommate! He's just a friendly dude who's a convenient narrative excuse to get a different kind of girl involved.

Brady was your standard, all-American, frat boy in training; he was a reasonable roommate, and jocularly friendly. The two of them were reasonably close, despite their differences. He came into the room, talking with someone over his shoulder - a slender blonde girl, wearing a simple white tank top and black denim shorts, with Chuck Taylor high-tops. She had a cute, narrow face, didn't seem to be wearing make-up, and had a silver stud in one nostril.

"Oh, hey man!" Brady greeted him. "Hey, uh, this is my kid sister, Katrina. She's thinking of coming here next year and I was gonna show her what campus life was like beyond the tours. Katrina, this is my roommate Peter, he's a good dude."

"Kat," the girl said, giving him a quick nod, before turning to punch Brady on the arm. "And I'm only a year younger than you, stop calling me your kid sister, I don't like it."

"Right, Right, Kat." Brady leaned in towards Peter and said, in a stage whisper, "She's trying to reinvent herself as cool for college but she's honestly a nerd like you." That earned him another punch, harder, from his sister. "Is it cool if she crashes on the couch tonight?"

Peter, for his part, was a little distracted - could they smell anything from the masturbation session he just had? Oh jeez, I hope I didn't expose someone else to it. God, I hope it doesn't work on guys, too -- I don't think I could deal with that. Peter was decidedly a 0 on the Kinsey scale, and did not want to deal with the consequences if it did. On the other hand, a small part of him was admiring his roommate's cute little sister. She had a slender waist and a cute little ass that he started fantasizing about splitting open. Maybe it wouldn't be so bad...no, no, this shit is crazy, I should listen to Miranda, and not try to dose anyone.

Thinking fast, he said - "Oh, uh, sorry the room is such a mess, let me clean up a bit," and proceeded to dump a few old instant noodle wrappers in the trash before starting to bag it up.

Katrina -- Kat -- turned to her brother. "See, I told you this place was a mess. At least it doesn't smell like your BO any more. It smells way nicer now," she said, smiling at Peter. "Must be your non-slob of a roommate."

Brady took a few exploratory sniffs with a confused look on his face. "Uh, I don't smell anything different."

Peter nervously piped up. "Uh, haha yeah, I did open the window, uh, be right back," and squeezed past the two of them to take the trash, with his potent tissues, down the trash. He might have been paranoid, but he could swear that Kat leaned in slightly and took in a breath when he squeezed past.

When he got back a few minutes later, Kat and Brady were outside the room, waiting for him. "So, man, we were gonna hit up this party -- nothing too crazy, but give her a sense of what she can expect out of UCLA. You, uh, wanna come?"
