After finding his sister-in-law masturbating in the shower, he couldn't resist and joined her. They both got wet and soapy, and he slowly began to undress her. She helped him take off her clothes, revealing her perfect body. He licked and sucked on her nipples while she moaned with pleasure. They moved into the motel jacuzzi where they continued their intense sexual encounter. He penetrated her deeply, filling her with his cock as she wrapped her legs around him. They fucked hard in the hot water, their moans of pleasure mixed with the bubbles. It was an animalistic, passionate encounter that left them both exhausted and satisfied.
