In fmf, we cum together, not to leave the girl's friend without an orgasm

I have 2 girls and I fuck them both to orgasms, what have you achieved?

I only fuck in fmf - there's a reason I let my wife's friend live with us

Friend girl, let's say my boyfriend fucks us, you lick the cum

While my friend is fucking my wife, I'm doing his girlfriend. Fair enough
