Ore no Karada, Tameshitemo Ii yo?: Midara na Oniisan to Mujintou Ecchi

Minato, a good-natured university student, is taking a ferry back home. On the trip, he finds Izumi, a beauty who gazes fleetingly at the waves. As he's captivated by him, he realizes that he's trying to jump into the ocean...!! Minato rushes to save him, but they both end up falling into the water... and getting washed away to a desert island!? They take their soaked clothes off and sit close together to keep warm... but Izumi looks oddly sexy with his skin exposed. With a suggestive touch, he says, "Actually, I'm into men. Do you want to try it?" As the both of them lustfully jerk each other off, Minato feels a wave of incredible pleasure...!!
