Chell and Mari, two sultry sisters, heat up the steam room, their bodies glistening with sweat. Chell, the daring one, suggests they explore each other's backdoors. Mari hesitates, but curiosity wins out. She lubes up Chell's tight ass, pushing in gently, causing Chell to wince. But as Mari finds a rhythm, Chell's moans grow louder, her pussy dripping with pleasure. Mari picks up speed, her fingers digging into Chell's hips, fucking her harder. Chell begs for more, her ass stretching to accommodate Mari's fingers. As they switch places, Chell tentatively probes Mari's ass, finding her tight and resistant. But soon, both sisters are crying out, their bodies shaking with intense orgasms.
