Eline and Peeter, bound by chains, their bodies pressed together in a dance of desire, explore each other's limits. Eline's fingers, slick with her own juices, trace the curve of her ass, pausing at her puckered hole. She pushes in, her eyes fluttering closed as she feels the intense pleasure of anal penetration. Peeter, his cock straining against his zipper, watches, his breath ragged. He reaches out, his hands replacing hers, spreading her cheeks wider, giving him a better view of her finger-fucking herself. The room is filled with their moans and the wet sounds of Eline's fingers sliding in and out of her ass, driving them both closer to the edge.
