Definition - What does Head Scissors mean?
Head scissors is when a woman clasps a partner's head in between her legs (face-bottom), squeezing the partner's head sensually to punish or force her partner into submission. Alternatively, this position could be performed by a male partner, but it is often associated with a woman straddling a partner's head and squeezing him or her into submission.
Kinkly explains Head Scissors
This is a great position for D/s sexual relationships. The dominant woman can pull her partner's face into her breasts and gently tease him to ejaculation.
