You finish what you started

You mommy always told you to finish what you started. Feeling his grip on your hair, you accelerate more and more your blowjob. He's swelling in your mouth, you can feel him trying to restrain himself, and this feeling between your lips makes you more and more excited by the second. His enormous shaft just slides between your over-sensitive lips, tickling them when his head penetrates you. You are losing your mind every second this goes on.

He arches slightly, moaning, and suddenly your mouth fills with his warm seed. It's like someone just turned a switch in your head, the mere taste of him sends shivers down your whole body. You tighten your lips not to lose the feeling, as your mouth literally starts overflowing with semen. You have never felt like that before, at the same time your whole body is full of pleasure, and you feel like you are not even yourself anymore, but an extension of his own body, a separate part that just fits so right. You feel at your place, complete and happy, as he continues cumming endlessly into your mouth.

It stops after a while. You've taken as much as you could but there was too much of it. You regain your calm, swallow a mouthful, which sends some more shivers down your neck, and proceed to calmly kiss and lick all that has escaped you earlier. You want it all, and continue until there is no more, kissing a few last time his manhood, finally at rest, as if to thank it from what it just did to you.

You crawl up into his arms, he gently takes you and puts casually a hand on your ass, petting it. He is out of breath and you are too. Before falling asleep, you simply whisper "Honey... you just made me cum by the mouth..."
