Emily felt both nervous and excited as she watched her stepbrother, Jake, undress for a swim party. Their parents were out of town, and they had promised each other to act like a normal sibling couple while hosting their friends. As Jake removed his swim trunks, his erection bobbed to the surface, revealing his desire for her. She couldn't help but feel drawn to him, their forbidden attraction intensifying with every passing moment. Emily stepped closer, reaching out to touch the hardness that threatened to burst from its confines. Jake gasped at her touch, pulling her into a passionate kiss that ignited a fire within her. They moved together, their bodies hot and slick with desire. Emily felt Jake's hands sliding up her wet bathing suit, and she gasped as he pinched her nipples through the fabric. They moved to the bed and began to make love.
