Reversible character in ch.4. True reversing in Ch.6, a sidestory to Neji no Kaiten. Disturbing shit ahead.
Reversing in ch.2-3. Warning: Disturbing
Reversing in ch.3 and ch.4. Sequel to Kyuuso Ha Cheese no Yume Omiru. I have to admit I really dislike this manga, but I don't like dramatic messy relationships and wishy-washy characters, but if that's your thing it's still really well-written.
Reversing in ch. 4.5 not really explicit, but I liked the story.
Seme vs. Seme with Doctors. One gives in right away, but it takes awhile for the other.
Ch.1-3 Couple reverses a few times. Ch.5-7 has a nice twist, some reverse foreplay/teasing, but no true reversing in the end.
Reversible Couple in Ch.1-2. Ch.4 has an uke who is reversible as the middle in a sandwich 3-some, it's a continuation of ch.1 of Konna Otoko ni Dare ga Shita.
First story has a ridiculous amount of reversible teasing, complete with detailed fantasies. But alas tis for naught! It really pissed me off because every chapter did everything it could to make you think it was heading that way, but every time it ended with the usual.
Reversible couple in ch 3
