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

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

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?
