「先っぽだけって言ったのに…」兄貴の彼女に頼み込んでゴム無しSEX!!

"You made three round trips already!" Mitsuki is my older brother's girlfriend, and he often brings her to our house. I am always annoyed by the pantings that come from the next room, but one day on his day off, my brother has to leave for work all of a sudden, and here comes my chance to be alone with Mitsuki!! What if give it a try, kneel down, and ask her for it? What? It's okay as long as I just touch her boobs!? I touch a girl's boobs for the first time, and judging from her moans and expression, she doesn't seem to hate it. I beg her for more. This time just the tip... but in the end, I go all the way in!! Mitsuki is so easy to persuade, so I'll entreat her repeatedly until I cum!! (Source: Eromangajima, translated) Note: Released in 81 episodes and sold as 27 chapters.
