Sister spilled cocktail on my clothes, I filled her panties

A woman in red lace underwear sits on a white couch, licking her fingers after spilling a drink. She straddles a man lying beneath her, guiding his cock into her pussy while pulling her thong aside. Her back arches as she rides him, moaning with eyes closed, then looks down at the camera as he thrusts up into her. The scene stays focused on their bodies and the couch, with spilled drink visible nearby.
