A woman's erotic holes can be divided into two categories: the reproductive organs and the anal opening, also known as the anus or monko. Even though men might feel embarrassed about certain areas being exposed, seeing a woman expose them and tease us by spreading her cheeks wide open while masturbating next to us provides support and encouragement during our solo sessions. And when she grinds against our crotch while making her own moans and groans, it feels like we are experiencing the ultimate pleasure together.
