Bold of you

As Sarah seems to sleep already, you decide to secretly take off your boxershorts.

After you did so, you wiggled yourself into Sarah's grip. It felt wonderful to be held against her. Her breath on your neck, her tits against your back, and her huge penis against your naked ass. Your heart's pulse was through the roof.

You proceed your idea and slowly, almost imperceptibly grind your ass against Sarah. You can feel how her shirt is slowly sliding up her belly, freeing her dick. Apparently, she's wearing panties that do absolutely nothing to restrict it.

You can feel how her dick finds its way between your asscheeks. You proceed to grind away, relishing in the feeling of being "taken" from the back.

It feels like Sarah is slowly getting hard. She also just started breathing a tiny bit heavier and now pushes her hips against yours again. Did she start having a wet dream?

You can feel her cock throbb slightly and then grow. She was getting hard.

You feel fluids slowly trickly into your crack. Just a little bit at first, but more and more the harder she got. Was she really releasing that much precum? Holy shit.

Suddenly, Sarah pulls back further, sliding out with most of her meat, but leaving the head at just the right position of your asshole. You froze up. That was not according to your plan. You wanted to take it nice and slow.

You clench your asshole, afraid of the impending impact. And its coming. Luckily though she still seems to be grinding without any intent on impaling you on her throbbing meat.

The push of her slick head against your ass still makes you clench though, but it makes Sarah release more and more precum, slickening up your boypussy.

Sarah seems to get into a rhythm of grinding like this. She keeps going for minutes and minutes and you start relaxing more and more. However, just as you relax the most, your ass unclenches and allows her head to enter. Pain curses through your ass and you grunt, unable to hold back any noise.

Sarah seems to love it as well, as now instead of long and steady grinds, she keeps going to tiny piston movements. Her head is staying in place, just inside your ass, but she's wiggling around, arousing herself even more. Her precum is now starting to lube your insides. You can actually feel the warmth spread throughout your ass.

You had read that the first attempt of penetration can be incredibly painful and needs a couple of minutes to adjust to the intrusion. However, those first penetrations are usually done with a finger, not with a dick of Sarah's huge size. But you decide to stay. You've already come this far and Sarah is giving you time to adjust. And on top of that, you're making the girl behind you feel good. What more could you want?

Sarah doesn't seem to be in a hurry. Still asleep, she just keeps doing those tiny piston movements. To her, your ass feels like velvet, and she just wants to stay there.

After around half an hour, you feel comfortable again. The pain has subsided, and you would be ready for more. You take up the rhythmic movement of Sarah and enhance them a bit. You can feel, how she's now rocking into you a bit, just an inch, back and forth. Is that what it feels like to get fucked?

It actually feels kind of good. You're comfortable and going slowly. Just the dick inside you defies proportions a little bit.

You and Sarah keep going. You dare to do the movements bigger and bigger. At some point you even scootch a little closer.

The pistoning now is not only larger, but also deeper. And just a you scootched closer, you found out about the reality of prostate stimulation. All of a sudden, intense pleasure courses through you, driving you over the peak of climax within seconds. You stain the sheets in front of you and ride out your orgams, all the while Sarah continues.

By now, she's been pumping precum into your ass for a good hour, and you start to feel it. Your belly feels a little bit full, and you can start to feel the warmth from it all. You shiver slightly at the pleasure and the image of being filled to the brim by Sarah.

As if on cue, Sarah speeds of her movements just before they are becoming a bit erratic. Your slight convulsions seem to have done enough to bring her close to climax, and now she's reaching for it.

Her erratic movements shake you with her, and after a couple of seconds, Sarah unleashes a flood of cum into your intestines. She keeps pistoning, sometimes regularly and sometimes spasmically. But she keeps going and going. You're not sure what's happening anymore, as your senses start to warr with each other.

On the one hand, you can clearly feel huge amounts of hot fluid being pushed deeper and deeper into you. But on the other hand, Sarah just keeps going.

After five more minutes, Sarah stills. Her cock still lodged in your ass, you can feel it grow softer. Some of the litres of cum she deposited inside you is starting to flow out around her cock.

And as you put your own hand onto your belly, you can feel that the skin has been stretched substantially. It almost looks like you had gained five kilograms, but only on your belly. It felt insane, and kinda interesting.

Then Sarah pulls you closer, putting more of her flaccid dick inside you. You yourself drift off to a very light and horny sleep where you're being filled with Sarah's jizz over and over again.
