For me a mechanical punt is where the lady makes you lie on the bed, rolls on the condom, blows you like a robot, then gets you fuck her in doggy for only a couple of minutes. I had quite a few of those with Eastern European escorts in Leicester a few years ago.
Another element of the mechanical punt is the massage, which I consider to be a time wasting tactic...... If I ever wanted a massage, I would go to a qualified physiotherapist, not a WG!!!!!!!!
