The Short "Vagina"

For this one, put the palm of your hand around the head of your penis, extending your fingers along the shaft (the thumb on top of the shaft and the middle and third finger on each side of the ridge under the shaft, the forefinger and the little finger being on each side). Using this grip, the head of your penis will bang against the palm of your hand every time you will penetrate the "vagina." With your free hand, you can lengthen the vagina or play with something else.
