We do mfm pretty regularly with a guy we know.
We usually cum inside her, sometimes she wipes off between rounds sometimes not, we don't play with the sperm but it's there for sure.
I LOVE to see him cum in her mouth, she always swallows without loosing a drop.
He's cum in her butt quite a few times, she dosent like the clean up after but it's still fun for all of us.
