When the panties/bikini can't contain all the dick and it pokes out. Honestly it's really a "balls in bottoms" Lora but I'll keep the name because it was the inspiration and it's more fun. Someone gave me the idea and thankfully I already had some stuff that fit the bill. Was trained on little smokies but it also works for other sizes, just prompt for what you want.
BTW, get in comments section and maybe you too could get your idea made into a LORA.
Trigger word: lil_peek
Helpful words: panties, bikini, shorts

This probably works for other sizes but in my testing it does small ones better when you ask for a small peen.
