Looking for manga where this guy works at a hotdog shop and really wants to give a bj because after watching a lot of porn he thinks it would feel good to suck a dick. So he practices on the hot dogs, but he wants the real deal. One day after school he brushes off his friends to try and do auto felatio and his friend get suspicious so he comes through his window and sees him doing that and laughs at him, but it leads to sexy times
