Collaborative sex stories let us write the plot together

(Her Secret Fantasy, continued by Anon...)

Rachel’s voice is more confident than before as she replies,“They like it even better when they cum on a big dick. They cum so hard they nearly lose their mind. That’s why they love it when a guy fucks them and says he’s going to nut in their pussy. That’s when fuckdolls… like me… cum on his big-” but she doesn’t get to finish.

“I’m gunna nut in your pussy Rachel!” yells Jimmy, grabbing her by the hips and thrusting his cock as deep as he can into your girlfriend.

Rachel’s head instantly snaps up and her eyes roll back into her head. Her mouth opens in a silent moan and her body convulses. Every part of her shakes, even her juicy thighs quiver with the power of her orgasm as they strain to lift her up as she arches her back. Finally the silence is broken as Rachel finds her voice. “I’m cuuumming! Ohmigod! I’m cummmming! So haaarrd! On your… ohmigaawwd… on your… fuck… oh fuuuuckk… on your big dick! This is the… the… besssttt!”

This sends Jimmy over the edge and he pulls Rachel down onto his cock by her hips again. He pushes his hips up as hard as he can to maximize the depth to which he penetrates your girlfriend as she continues to cum. He has to hold on tight because Rachel is bucking like crazy. It’s almost like she’s being electrocuted as she shudders and shakes while emitting a constant stream of squeals and half words. Her flushed upturned face shows that her eyes are crossed, her tongue is hanging out of her open mouth as drool runs over her pretty pink lips and down her chin.

“Sweet Jesus, ” you gasp out loud, “he’s turned Rachel into a fuckdoll with Ahegao face on command.” You had no idea it was even a real thing. The first time you saw that word was in some kinky erotic “choose your own adventure” story site. That was a half-hour of interesting “research.” But yeah it is a thing — your girlfriend is living proof right there on camera no less. All it took was some half-assed hypnosis and a frat-boy chad. That escalated quickly, you think, glad that you at least had the wherewithal to ensure Jimmy was out of the picture before you got Rachel home. This is one guy you don’t want hanging around Rachel.

Unpausing the recording, you marvel at how long Jimmy can keep going. Despite your Ahegao-faced girlfriend spasming on his cock, he manages to keep pumping in and out of Rachel’s tight pussy over three dozen times. You’re even more surprised at Rachel as her orgasm never ends, her head flopping back and forth as trails of drool run down her chin. Rachel’s vocal commentary degrades into incoherent grunts and moans punctuated by Jimmy’s thrusts. “Oh, oh, oh, ohmigod, oh, oh, ugh, fuck, ugh, fu, fu, fuck, ugh, oh, oh mmmygawd, ugh, oh, oh, fuck, oh fuck, oh fuck, oh fuck, ugh, ugh, oh, fuck, ohmigod, ohmigod, oh, ugh, ugh, oh, oh, oh fuck, oh fuck, oh fuuuuck!”

Finally Jimmy finishes filling Rachels pussy with cum, and the recording goes blank. The image of your girlfriend’s mouth wide open in the midst of orgasm, tongue hanging out, cross-eyed and drooling, is burned into your retina. You immediately rewind and watch the last five minutes over again, careful not to touch your dick lest it explodes.

You’re seriously confused as to how you managed to not be conscious enough to remember what just happened. Ah well, perhaps you can give it a go tonight when Rachel comes home from work. Having your own private fuckdoll which you can turn into a drooling Ahegao mess every night while she comes on your dick is a dream come true. Being able to switch her off when you’re done, and her being happily oblivious, is the icing on the cake. She clearly really enjoys it too. Win-win. This thought is too much and you spontaneously ejaculate, covering your pants with the biggest load you’ve ever produced. You pass out for about five minutes, such is the physical and mental intensity.

Waking up from your sex-induced high, you become a little concerned. Playing things back in your mind, it’s pretty clear that the nature of the trance changed over the evening. Rachel became increasingly immersed — absorbing things into her hypnotized psyche. Reflecting on the “creamy yoghurt” and banana incident this morning, some elements have also carried over into her normal personality. If only you’d been fully aware of the events last night to notice the changes in the trance, you might have made more of an effort to get your girlfriend out of there and been less self-centered. The subliminal implantation probably consolidated everything, and in hindsight was probably a mistake. Having said that, you can see plenty of upsides to the present situation and few downsides. Although you might have to change the key word just to be safe.

As you walk to the bathroom to clean yourself up, you wonder what the rest of the day holds.
