Slim brunette covered in mud jerking off with bottle on couch

She’s lying on her side on a low couch, completely bare, mud slicked all over her body—thick on her thighs, stomach, and chest. The bottle is long, glass, maybe a wine bottle, and she’s sliding it in and out with steady pressure. Her eyes are closed, hand working the base, occasionally shifting to rub her clit. The lighting is soft and natural, like late afternoon through a nearby window. You can see the mud cracking slightly as she moves, especially when she spreads her legs wider in the wider shot. The angle stays mostly to the side, tight on her lower half, then pulls back briefly to show her full body from the front. No talking, no cuts to other people—just her, the bottle, and the slow, wet sound of her rubbing through the mess.
