Swallowed every drop, now her body’s overloaded with protein

A woman in glasses and a beige top performs oral sex on a man, taking his penis deep into her mouth and throat. She then shifts to straddling him, guiding his erection with her hand before riding him. Close-ups show her gripping his shaft and his hand caressing her vulva as they continue. The dimly lit room and her tattooed arm are visible throughout.
