They are betting that men can't get pleasure from nipples Hiji actually ended up cumming from his nipple alone but he won because doesn't say that his nipple feels good In the end hiji pinch gin's nipple, and i think his nipple fall off lmao (But on the side note yes your nipple can actually fall off, be careful)
Ch.1 Oooohh... me likey I myself don't know and understand the pleasure of having my nipples played when I do it myself.. hmm.. I'll probably try it out w sm1 someday ig
