A position in anal
sex, where the receiving partner(bitch, bottom, catcher) is on top. The receiving partner bounces up and down on the other person's penis(or cock, or dick whichever you prefer)hence the term "bunny hopping".
Sean knew his boyfriend's ass was a "one way street" but he still felt
to be on top every once in a while, so he decided that
bunny hopping would be an acceptable alternative to their normal routine.
