It seems like tumblr eats asks again, cos the “a1” was the second part of my ask “a” which was the missing part for the ask 1+2+b some time ago. It fits even without part a, but I wanted to share the idea that Peter is not the slutty!Peter but the Peter i nerdy-shy-pristine-still-a-virign-uncle-who-rolls-in-dirty-underwear.

gosh darn, tumblr. get your act together 

I can def get behind virgin!Peter, though my answer wouldn’t really change, to be honest. I’d love for Peter to squirrel Derek’s dirty underwear away, getting secretly off on how his younger nephew has become this oversexed adonis. He probably rolls around in the underwear like a cat in heat and uses it to jerk off into it – all quick and fumbly because he’s nervous someone might come in and catch him.
