You decided to not release in public.

Though, it was getting harder, literally. Everytime you moved a little since you was uncomfortable in your sit, you felt your dick rub against the fabricnof your clothes. You moaned lightly, noticing how exposable your boner was. You was in the back of the train, the only sest there was you on it while everyone else was far away from you, standing or sitting. You kept moving a bit, feeling yourself about to cum but shortly stopped since someone was looking at you. Oh god, I'm so hard. But I can't do it, you thought, covering yourself. The guy who was staring at you was really hot. And that made you even harder.
