corkscrew
Welcome to corkscrew!
How To Do It: Near the edge of a bed or bench, rest on your hip and forearm and press your thighs together. Your partner stands and straddles you, entering or grinding from behind.
Why: Keeping your legs pressed together during this sex position allows for a tighter hold on your partner as they thrust.
Make It Hotter: Instead of letting your partner do all the work, try thrusting your hips slightly to match the tempo.
