When Marge Simpson and Lois Griffin accidentally switch soaps in the carwash, their sudsy encounter takes a provocative turn. Marge's favorite lavender soap suds up Lois' cleavage, while Lois' pine-scented soap bubbles drip down Marge's stockings. As they rub each other down, their carnal desires awaken. Marge's tongue laps at Lois' nipples, and Lois returns the favor, sliding her hand between Marge's thighs, finding her wet and wanting. Their carwash tryst becomes a symphony of slippery flesh and ecstatic cries, leaving their cars spotless and their bodies spent.
