Face-Puppetry
When you're giving head so good, you're basically the tongue of a god, and you're gently touching her leg right before she blows her load, making her squeeze your face like it's the last burger at a fast-food joint on a Sunday night.
I was giving head so good, she grabbed my head like it was the last slice of pizza.
He was touching her leg just before she exploded, and she clamped down like a vice.
She was about to cum, and he moved his hand just right, and she squeezed my face like it was a stress ball.
