Uhh the only one I can think of like this is a Harada story...and it’s a dj...and becomes shota......
But I’ll leave it here, emphasizing again it has shotacon and it’s Harada so it’s disturbing http://www.mangago.zone/read-manga/gintama_dj_wakagaeri_hen/
Drop a yaoi where the uke/seme becomes tiny and the other one isnt and they have some smex thankyou!
