Boku no Hero Academia - Kenzen Friends (Doujinshi)

Bakugou Katsuki/Todoroki Shouto/Midoriya Izuku (switches/versatile/reversible) A gag 4koma with some crossdressing and genderswap elements. The future daily life of the pro hero trio in which having sex is simply considered exercising, with no love component. No feelings. Just wholesome screwing around, while they all live alone.
