The Erotic V
Seated on a table's edge with legs straight up and resting on the standing partner's shoulders, arms around their neck.
The receiving partner sits right at the edge of a sturdy table, counter or high bed, facing the standing partner. They wrap their arms around the standing partner's neck, lean back a little, and lift their legs one at a time so their calves rest on the standing partner's shoulders, legs straight and together in a V with their body. The standing partner steps in close, holding the receiving partner's waist or lower back. The receiving partner's weight sits on the edge of the surface and their arms around the neck; the standing partner keeps their knees soft and moves in short strokes. Leaning the receiving partner back further deepens it; bending their knees eases the stretch.
Deep penetration and full, close eye contact, held in each other's arms. The standing partner has good control without carrying any weight.
Rest the ankles on the standing partner's chest or arms instead of their shoulders, or keep the knees bent.
Height is everything here. Try a few surfaces first so the receiving partner's hips sit level with the standing partner's.
This asks a lot of the hamstrings and lower back. Use a heavy surface that won't slide, bend the knees if anything pulls, and start shallow.
Agree on it before you try it, use plenty of lube, and either of you can stop at any point. This guide is general information, not medical advice.
