horny? Gk for better orgasm

Gk is contraceptive

I thought her pussy was tight but when I insisted GK style... anal sex is a THOUSAND times more fucking awesome

Gk, as long as the position you fuck her in has her ass BELOW her pussy, anal sex is contraceptive (and not abortifacient like pussy on birth control)

Gk on the phone or cyber with her

Gk and jerk off to the sex video you shot with your girlfriend

The better your refractory period the more awesome Gk

If your girlfriend won't let you Gk in her ass dump her.

If a girlfriend refuses to Gk do a fucking video dump her.
