In the crystal-clear waters of their backyard pool, Marge and Homer find an unexpected intimacy. Marge, her petite breasts bobbing beneath her bikini top, swims languidly, her legs brushing against Homer's. He, with a mischievous glint, pulls her close, his hands roaming her body, cupping her small, firm breasts. She gasps, her nipples hardening, as he tugs at her bikini bottoms, freeing his throbbing cock. They float, entwined, as Homer plunges into Marge's welcoming warmth, their underwater world filled with bubbles and ecstasy.
