Stumbling upon my buddy's wife in their private moment, I can't help but appreciate her luscious, rounded bottom as she bends over, oblivious to my presence. Her tight, little ass cheeks clench and relax, teasing me with every movement. She's wearing a thong, the fabric barely covering her plump lips, inviting me to imagine the warmth and wetness hidden beneath. I struggle to keep my composure, my cock throbbing in my pants, aching to replace the flimsy fabric with my thick, eager shaft.
