Digging through women's underwear when they're not looking
I've done this several times already. I'll name a few instances and let me know what you think of each of them.
1) I had a bit of a crush on my best friends sister once so when he left me in the place alone and no one else was home, I snuck into her bedroom and stole a pair of her underwear and later beat off on it.
2) in college there was a cute lady doing her laundry that I had a bit of a crush on. When she wasn't looking I took a few pairs of her underwear when she wasn't looking and did the same to it.
3) I currently have a female roommate. I don't know if I like her or not but I looked through her underwear drawer when she was gone today too.
