Bend Over

Here we see scenes where the body arches, the back hollows, the posture inviting rear entry. It's often an invitation to get on all fours, or to lean forward, ass in the air, to better receive. The view from behind, with exposed buttocks, is central. It can be seen as a form of voluntary submission, an attitude that sets the stage for sodomy or simple anal penetration. Pleasure can come from the sensation of being penetrated this way, or from the pleasure of penetrating someone adopting this position. It's a position that highlights the posterior and can be very exciting for both partners.
