[Requests Accepted] [MTBs] ボテ腹xふたなりx胎内回帰 あなたのことを産んであげる [RJ01119207]

During a date with your partner, you suddenly fell ill with a strange disease. The only treatment is to return to the womb. Your partner, who is suitable for this, steps forward. You are connected by a life cable, transforming your body into that of a fetus, and then entering her body. You successfully achieve the regression, but during the recovery process, your penis becomes gigantic. She ends up with a bulging belly and becomes a futanari.
