You slowly push yourself all the way in.

Karen reaches her hand down and puts it on her hip as you slowly push yourself all the way in. Your balls and groin tuck into her butt cheeks as your dick slides up into her ass as far as possible. You begin to slowly pump yourself in and out of her until you feel her muscles loosen and it becomes easier.

There is no doubt you are both thinking about her first ass penetration and how this is the result. You are two equal bodies, united in love. Now, she has submitted herself to be used for your pleasure. The young Chinese girl has opened up herself to assuage your lust, and you are hungrily devouring what she offers you.

The juices from Karen’s cunt that is mixed with yours is now lubricating her anus. As your shaft courses through her textured orifice, the walls of her rectum begin secreting it's own lubricant than mixes with the juices you are introducing.

In and out you slide your penis through her anus. Andrea squeezes Karen’s buttocks and giggles happily as you ram yourself against her firm muscle, jolting her body with my thrusts. Your scrotum slaps at her wet cunt and smears our wetness on both our bodies.

Karen feels your tempo increasing and leans back to smile at you and watch your hips buck against hers. You pause, pushing your shaft deep inside the Chinese ass and lean forward to give Andrea a kiss. You pull her face closer as you kiss her passionately. The doctor responds, breathing deeply and kissing back with her wet lips.
