Anatomy and biomechanics
Posterior approach in prone decubitus with leg adduction: receiver face down with legs together, which narrows the channel and increases friction; penetrator on top with legs on the outside. The angle is closed and superficial but very stimulating due to the friction; low effort for the receiver.
Why this position works
Legs together narrow the channel and multiply friction, creating a very intense and enveloping sensation despite the shallow penetration. The receiver is completely relaxed face down, and full body contact from behind adds intimacy. Ideal when seeking friction over depth.
The Fan: legs together, maximum friction
Sometimes less opening is more pleasure. In the fan, the receiver is face down with legs together and the penetrator on top: the channel narrows, friction increases, and the sensation becomes very enveloping.
Also known as: the fan · legs together · closed prone · face down together
Variations of this position
1. High pillow: better angle
Like the fan, with a firm pillow elevating the pelvis.
A firm pillow elevates the pelvis and opens the angle while keeping the legs together.
- Place a firm pillow under the pelvis.
- Keep the legs together.
- The penetrator fits the angle.
2. Crossed: legs crossed
Like the ventilator, with the receiver crossing their ankles.
The receiver crosses their ankles, further narrowing the channel for maximum friction.
- From the ventilator, cross the ankles.
- The channel narrows further.
- Maximum friction; gentle rhythm.
✓ Tips
- A pillow under the receiver's pelvis greatly improves access.
- Legs together are the key: don't open them.
- The penetrator distributes their weight to avoid crushing.
- Soft rhythm; the friction does the work.

Frequently asked questions
Is it deep?
Not much, but the friction from legs together makes it very intense.
Who is it ideal for?
For those who enjoy friction and prefer shallow but very sensitive penetration.
Does it tire?
Not at all for the receiver; the penetrator must distribute their weight well.
