Summary Believe Me! I Offer You My First from Kainu Manga
Believe Me! I Offer You My First summary: There was this girl on the street trying to recruit people for her religion, and she was totally my type-- so I flirted with her a bit and somehow ended up taking her virginity. In return, she begged me to come to their church, saying that's all she wanted. So I went there once and... what the heck? This place was a cult?
