Please be the partner for this virgin's first experience!! We prepared a scale that could measure exactly, and we called out to a beautiful female college student and negotiated directly with her, saying, "If you can collect 30ml of sperm in the container, we'll give you a prize!" At first, the girl was hesitant, but she gradually became horny, and in the end, she straddled the dick and shook her hips wildly! It was a continuous sperm milking challenge in a raw vagina!
