End of Part 1
It was then that I began to notice that my cock and balls were beginning to ache. "Oh no," I thought to myself. All her teasing and abrupt stopping was giving me blue balls. I briefly thought about leaving until I realized my clothes were gone and had no idea where they were.
So here I was stuck here with nothing but her panties on and a raging erection and blue balls. As I paced around thinking it couldn't get much worse, I hear a key being put into the lock. "Oh crap," I think to myself. It could only be her roommate...
Part 2
There was no time to think let alone hide as the apartment door suddenly opened and my girlfriend's roommate Cassie was there.
"Oh, hi Brett." she said before suddenly devolving into a fit of giggles. I couldn't really blame her. If I had walked in on a guy wearing nothing but a frilly pair of panties I would probably die laughing too. After a few seconds her giggling fit turned into full on laughter as she lost her balance and leaned up against the wall holding her stomach. After a few more minutes of this Cassie finally got control of herself back and looked back at me with a wide grin on her face.
I was burning with embarrassment as she said, "I can't wait to hear your explanation for this. And where's Jenn?"
"Jenn had to leave to help her sister." I said meekly.
Still smirking Cassie said, "So you just decided to put on some of Jenn's undies while she was away?"
"No not exactly." I muttered. "She had me put them on before she left."
Bemused, Cassie said, "And you didn't think to put your clothes back on while you waited for her to come back?"
