Attempt to pin her down

You push the girl down, pinning her arms.

You smile, thinking you've won.

But the girl grins and her legs, which you failed to pin, snake around your neck.

Her ankles lock behind your back and her legs crush your neck.

Grinning, the girl moves her hips and drags you to the ground, still trapped between her thighs.

You try hard to escape, but her legs are like an iron vice.
