Unbeknownst to her husband, a busty sister-in-law teases her horny cousin by parading around in skimpy, wet panties. Her ample ass and thick thighs are on full display, driving the young man to desperate wanks in his room. One day, she catches him mid-act, his cock throbbing and ready. With a wicked grin, she orders him to keep going, watching greedily as he strokes out a massive load onto his abs.
