If double penetration is high on your sex wishlist, the Double Stuffed position is where it's at—this threesome sex position doubly penetrates the partner in the middle.
While simultaneous vaginal and anal penetration is certainly possible, this sex position also allows for double anal penetration with a few angle swaps. However you decide to make it happen, get ready for some serious fullness!
To get into the Double Stuffed position, have the bottom-most partner lay down on a flat, plushy surface. From there, the receptive partner can straddle their hips while getting on their hands and knees. We recommend the receptive partner get fully penetrated by the bottom partner at this time—not only because it ensures the angle is workable for the initial penetration; but also because it allows the receptive partner to get used to the sensation of fullness before the second partner is involved.
After everyone is comfortable, the from-behind penetrating partner straddles everyone's thighs to kneel with their hips touching the butt of the receiving partner. This puts them in place for penetration. We encourage the top partner to penetrate the middle partner extremely slowly and patiently to ensure everyone's comfort.
When ready, start off the Double Stuffed position by requesting the receiving partner to move. This allows the receiving partner to control the initial sensations and depth as they get used to the penetration.
