V is for Velocity
Yes there are some who enjoy sex at speed.
I am told that in the old days it was possible to join the tun-up club on the M1. Now of course, with speed restriction and seat belt law that is no longer possible. Some claim that now we have gone metric that having done 100 Km they have joined the tun-up club.
Even if it was only a Monica.
My self, I joined the Bi-tun-up club in the back of a light plain. Others have gone faster. The Fastest record must be held by an orbital crew. I will not say if they are Russia or US. We do not identify other swingers do we!
