For a certain fee now any stranger is ready to take off her clothes, spread her legs and suck the first man she meets. Every cute girl is weak in the face when she sees bucks in front of her. I wouldn't want to be a pickup artist because it's a risky business to fuck unknown holes. Sure you can use a condom, but rubber doesn't always save the day.
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!
I don't like these videos, you're porn stars
