Fill the condom

You find that of all of the ways you could feel his cum, you want to feel the heat of Alex's seed inside of your fertile pussy. "Keep it in me when you cum," you moan, the words alone sending a slight shiver down your spine. The idea that there's only a thin barrier between you and pregnancy is an exhilarating thought, and you're surprised and a little scared at how much it turns you on.

Alex grunts his approval as you feel his hips speed up even faster and his strokes become shorter. Only a few seconds later, he pushes himself firmly against you, embedding his dick completely. You first feel the shaft throb and then a slight warmth bathe the deepest parts of your pussy. You had no idea how satisfying it would feel to have him unload while holding himself inside. Once Alex is finally spent of his seed, his grip on your hips loosens, and he rubs your outer thigh lightly, saying, "Damn, that was amazing."

After resting for a minute or so, you feel Alex begin to pull out and hear him say, "Oh, shit!" You turn your head to the side and ask him what's wrong. He looks up from where the two of you are joined and with a hint of panic in his voice, he responds, "It's... umm... I think I heard a car pulling up, we need to get dressed, quick!"
