__Semen splatters across her back__ as he pulls out with one last thrust, leaving sticky trails down her spine. POV shot of his cock dripping onto the floor after years of forbidden tension. Thick thighs clamped around him, nails digging into wood like she’s trying to hold on longer but can’t. He flips her over mid-cumshot—her pussy still twitching—and finishes on those trembling lips while she pretends not to notice someone watching through the crack.
