Making use of the simple bondage functionality of the Liberator Black Label Wedge, the Bind and Bang makes it easy to add a bit of bondage into this standard, modified missionary position. Using this wedge also makes the position that much more accessible to people with disabilities and/or chronic pain.
To get into this position, the receiving partner should lay flat on their back with their hips propped up in the air by a sex furniture wedge. As pictured, the receiving partner should also have their wrists bound to the sex furniture (if that's comfortable for the two of you). The penetrating partner then kneels in front of the receiving partner, leaning in towards their hips, to penetrate.
Before anybody gets into position, it is important to have a discussion about pain, expectations and accessibility so that it can be done safely and sexily.
