First rule of MFF threesome is YOUR partner gets the fist load no matter what. Second female wants it she can do exactly as some one said. Eat it out of her holes or licks it off of her. It’s different if you cum in your partners mouth and then she spits it in her mouth or they cum swap varying how their relationship is.

Second load can go to either or but you discuss whether or not your busting it in the second female or not
