Strike while the iron is hot

You push her forward, away from you. You get behind her and place your dick right at the entrance of her pussy lips, planning on some teasing. It didn't work. She doesn't wait for you and presses her pussy hard against your dick, and you slide all the way inside. You groan softly, feeling your dick inside your girlfriend. "I see that you still have the power to fight back."

She ignores you and starts moving, slapping her ass against you. Not wanting to lose your momentum, you push back, increasing your pace. You both go at it as if the world will end, and you start to feel the pressure building up inside your dick. "I can't lose this!" you say, grinding your teeth. You bend over her to stop the rhythm, move a hand towards her pussy and one towards her tits, and start working your magic.

"Don't stop. This feels so good," you finally hear her speak. She was approaching orgasm, and you could feel it. Suddenly her vaginal walls clamp down on your dick, but you remove it before she can capture it. "Aaahhh!" You hear her scream. She finally falls with her face in the bed and her ass up in the air presenting you with a beautiful sight. But your dick is still red and hard, but at least it's your victory. And what a victory! It looks like it's an effort for her to even breathe.

"Heh, I think that's 2-0 !"
