The manga was with the uke who didnt have sensitive nipoles but the seme seemed to like sucking on them anyway. So one day the uke came up with the idea of getting his nipples sucked by a sucker toy thing and made his nipples extremely sensitive. All i remember. Please help! Thanks!

Manga isnt NUDE btw thanks

I found it! If anyone wanna read it it's Zankokuna Kimi to Tomoni thanks for helping though! 🙂
