There’s a reddit post about a roommate “doing things” with his roommate’s girlfriend’s body wash that will make your scenario downright awesome.

If you come across it share it because I love to read that stuff! Also, probably exactly why I haven’t had a roommate since I was 22 lol
Ok. If you’re sure. It’s pretty f’d up.

I just busted a gut reading that. I hope it’s made up.
I have mostly proceeded believing that this is flat out fake. but we live in a world of sociopathic demons so . . .
I had two friends who were roommates that had a beef in college. One definitely was spoiling the shampoo. So the story above is plausible. Now whether it’s scientifically possible to get someone pregnant like that I’m not sure.
Yeah, it’s dicey at best.
I still like the first comment to the OP. Hilarious.
