Accidental cumshot inside my stepsister on Christmas while everyone was sleeping

Stepbrother wakes to the soft glow of Christmas morning, his hand already wrapped tightly around his throbbing cock. Stealthily, he slides into his stepsister’s bedroom, her body invitingly exposed under the covers. She stirs, eyes fluttering open, a mix of confusion and desire crossing her face. With gentle but firm hands, he hikes up her nightgown, fingers tracing the curve of her hips. Her legs part, granting him access. He teases her entrance, feeling her wet and ready. As he thrusts deep inside, the world outside fades away. The room fills with the rhythm of skin on skin, their breaths mingling. A rush of pleasure overwhelms him, and he spills his seed deep within her, the sensation intense and forbidden. They lay there, hearts pounding, as the scent of their passion lingers in the air.
