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.
