ROCKET 17th Anniversary User Request: Gender Transition Calendar ~The 10th of each month is Gender Transition Day~ RCTD-687

Every month on the 10th of the company calendar, a mysterious "swap mark" is drawn. Swaps occur according to mysterious rules, with blurred self-awareness and memories… Who rewrote the world?! A forcibly implanted swapping fetish! Sex with women's bodies! Heart racing and rubbing against each other during lace-clad sex! Chaotic swapping and orgy sex! Despite feeling disgust, one is addicted to the pleasure!
