Alyx Star gets fucked in her friend's gift

Lucas wants to give his girlfriend a surprise birthday celebration. Alyx Star, her best friend, stops by to assist with the planning. In addition, Lucas needs input on the gift he gave his girlfriend—some sultry underwear. Because the bra is so large, Alyx is certain that her friend's underwear won't fit. Alyx puts on the underwear to demonstrate it, since her tits are considerably larger. It turns out that Alyx fits it flawlessly, meaning her friend's boobs will be too enormous for it. Never one to pass up a chance, Lucas gets Alyx to fuck him in the underwear that was intended for her girlfriend.
