My childhood friend who now lives in Kansai suddenly came to stay at my house! He ends up bumping into his girlfriend's girlfriend, and the atmosphere becomes awkward... My childhood friend, who I thought didn't see me as a man, got jealous and got on top of me and started moving her hips violently in cowgirl position, ejaculating as hard as she could with a pile-driving butt piston. From that day on, I rode my childhood friend's big ass in cowgirl position.
