If the Minotaur took you from behind, you have to wait for him to recover and his dick to deflate ... it´s meant to be that way for increased humiliation ...
"Wait" when he´s done and a "clock" should appear on the image ... click the "clock" for "Long Wait" ... or keep waiting manually ... resisting just affects the increase of damage/soreness during sex ...
If the Minotaur took your snatch, you should be free after he blew his load ...
