Convincing a voluptuous mother-in-law to undress following self-pleasure and climax on her ample derriere

After a long day at work, I found myself in the company of my voluptuous mother-in-law. She was lounging on the couch, her ample curves begging for attention. I couldn't resist the urge to indulge in a little self-pleasure, my hand finding its way to my throbbing member. As I began to stroke myself, my eyes were drawn to her luscious, round ass. The sight was too much to handle, and I found myself unable to resist the urge to cover her ample derriere with my hot, sticky cum. Fortunately, she was more than willing to accommodate me, bending over and presenting her fat, hairy ass for my eager consumption. The sight of her thick, hairy ass glistening with my cum was enough to send me over the edge, and I found myself climaxing all over her. The experience was truly unforgettable, and I knew that it was only the beginning of our wild, kinky adventures.
