The receiving partner lies on their back with the penetrating partner lying perpendicular.The receiving partner bends the knee closest to the penetrating partner's head enough so that there is room for the penetrating partner's waist to fit beneath it, while the penetrating partner's legs straddle the receiving partner's other leg.The in-and-out thrusting action will move more along a side-to-side rather than top-to-bottom axis.This is sometimes called the scissors position.This position allows for breast stimulation during sex, for partners to maintain eye contact if they wish, and for a good view of both partners as they reach orgasm.
