The receiving partner may lift the upper knee to allow for easier penetration. For penetration, the partners may separate their upper bodies, with just the pelvises connecting, and their legs can also rest on top of each other.
In the sex position, the receiving partner would be in the inner spoon position and the penetrator is in the outer spoon in preparation for rear-entry penetration. The spoons cuddling position is not limited to two people. In the spoons cuddling position, one partner lies on one side with knees bent while the other partner lies with his or her front pressed against their back.
