In the main variation of Lap Dance, the woman sits astride the man with her legs positioned inside his, allowing her to take the lead and control the depth and speed of penetration. This position requires significant leg strength from the woman, so it's important to communicate and adjust as needed to avoid strain or discomfort. The position offers a wide range of motion, allowing for a variety of movements including front to back, side to side, and circular motions. This can create a sensual and intimate experience, as it allows for eye contact and close physical connection. Additionally, the man can use his hands to stimulate the woman's breasts or clitoris, adding another layer of pleasure to the encounter. Remember to take it slow and communicate openly to ensure a pleasurable and satisfying experience for both partners.
