3rd Muscle

The supernatural ability that some women’s pussies have to grip a dick during a vigorous banging session. It will usually result in immediate jizzing for all but the most experienced men.

Pat: Was that broad you brought home last night worth another run?

Lee: She was like a unicorn using her magical superpowers of the 3rd muscle to grip my dick I lost it and filled her full.
