What? A talented Pervert?

Issei was going to be such a successful person when he was a kid. But the faithful day he experience the true meaning of boobs he gave it all up and lives the life of a pervert. But when he is exposed to devils he may just want to bring his old skills back from the dead. That doesn't mean he'll stop loving boobs however. Issei/Harem. May change to M rating later on. No lemons tho.
