The teen step-sister's heart raced as she felt his warm breath against her neck, his muscular body pressing against her soft curves. She couldn't believe she was about to let him do this to her, but she couldn't resist any longer. She arched her back, offering him her luscious ass covered only by sheer pantyhose. He groaned, the vibration sending shivers down her spine. With gentle yet firm movements, he slid the material to the side, revealing her pink, puckered entrance. His cock, hard and ready, teased her opening before he slowly thrust inside. Her breath hitched as he filled her up, claiming her in a possessive embrace. The sensation was overwhelming, and she couldn't help but moan his name. Their bodies moved in sync, creating a rhythm of passion that left them both on the edge of ecstasy.
