Marital sex just needs to be varied. If the couple won't do it together, then clearly they will still do it secretly each separately! I think this home variation is acceptable, in any case it is not as extraordinary as entertaining a large group of swingers. My wife and I once invited me to one of these, against her this clip is just sex puritanical family!
Guys come and go, and money and good sex never hurt a girl. You could see how her eyes lit up at the sight of the bills, and with what poorly concealed pleasure she was rubbing his cock with her tongue.
