The partners sit, facing each other, while the woman wraps her legs around him. This position allows for slow, meditative type of sex.
Recline the back seat to create more space; the man is in the rear on his side while the woman also lays on her side in front of him. The man enters from the rear. This is not only comfortable, it also enables the lovers to relax.
Warning: Turn off the car engine first if you don’t want this to be a one-way journey!
