I got excited and got an erection when I saw my neighbor's wife's unintentional thong-flashing from behind. Realizing this, the wife who had been out of touch seized the moment to show off her proud big butt, biting into her thong with force, adding to the temptation! She squeezed and rubbed my hard-standing penis between her thong-clad, plump buttocks, doing whatever she wanted to do! Reaching the limit of my desire to penetrate, I slid her thong aside and took her right there, raw and quick! The big-butt wife, transformed into a sexual monster, squeezed my balls empty, milking my sperm out multiple times!
