I fucked my sister in law at night.

In the dimly lit bedroom, the moonlight casts an ethereal glow on their entangled bodies. She, your gorgeous sister-in-law, her eyes shut tight with pleasure, her breath coming in ragged gasps. You, her brother-in-law, assert your dominance, taking her roughly from behind, your muscular arms holding her in place as you pound into her sensitized flesh. Her body arches instinctively, her moans echoing off the walls, her fingers digging into your shoulders as she begs for more. The sound of flesh slapping against flesh fills the room, each stroke taking them closer to the brink of ecstasy. Finally, you both reach the climax, your release pulsing deep within her, marking this forbidden union forever etched in their memory, their spirits, and their flesh.
