Macca Slapper

The 'Macca Slapper' is a unique technique which is hard to master. Founded by the great Macca Slapper himself, you must thrust your junk up and down creating a clapping effect from your nut sack and penis slapping against your skin. This technique is for men only.

My boyfriend can do the Macca Slapper, he is way better than yours!

My Macca Slapper sound makes the whole room vibrate.
