Mink and Aoba board a public transport train. It’s so crowded that they get cornered in the back and all this pushing against each other starts making Mink hard. Aoba backs up and feels something against him. knowing what it was, Aoba daringly starts by rubbing the bulge mischeviously. Then slips his hands inside and massages Mink member with vigor. Mink is trying hard not to make noises or the people right behind him might hear. Luckily his coat was long enough to hide the action.
