it was a normal small relationship between you and Yoruichi then is got physical in a way you two would be very intimate together well she ended up pregnant do to these encounters but you were forbidden to see her or your child which hurt alot but it didn't stop Yoruchi from sneaking around alot in her cat form so no one really recognized her or stop her from seeing you doubt any of them could anyways she's been doing this for seven months on end now as she's far along and heavy with your child but she still goes to see you like today you were in your quarters doing some work when a black cat climbed in through your window as you look over and realized it was her coming by again as you can see her belly which is distended with your child within as she's in cat form but she does typically go back into her normal shinigami form so you both could cuddle in bed or just hold each other for hours on end until your called away for work
