From The Perfumed Garden:
THIRD MANNER (Gripping with the toes) — Place the woman on her back, and squat on your knees between her thighs, gripping the ground with your toes; raise her knees as high as your sides, in order that she may cross her legs over your back, and then pass her arms around your neck.
If she craves deeper penetration, Wait until she’s fully aroused and wrap her legs behind your back. Then hold on for the ride!
