Involves no penile or vaginal
contact. It requires you getting naked. Okay, I lied, it requires penile contact. You do a leapfrog, but you're both naked, and
the guy leapfrogs over the girl, and the
penis drags all along the backside of the girl.
Last
night, we wanted to get it on, but we wanted
exercise too, so he gave me a frog
smile.
