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

At this point your so goddamned horny that when Monica pulls her head off your cock to take a breath you pop up onto your knees. Taking her cue from you, she immediately gets on all fours in front of you, wiggling that amazing ass of hers.

You glance up and see your girlfriend writhing in the chair, frantically fucking herself with the massive pink dildo. Rachel is now slapping at her clit and you can tell she’s nearing what will be a pretty intense orgasm.

You rub the swollen head of your prick up and down Monica’s slit and you can feel the warmth and wetness, then your slide your saliva soaked cock into her. She’s so wet that there’s little to no resistance as you slide all the way in and she makes a loud grunt as stretches to hold your entire length in her pussy.

You remember a story that Rachel told you once that got you so turned on, when she said that her best friend discovered she loved it rough. Ever since then you’ve held a secret desire to just pound away on Monica, and may have even thought of her once or twice while fucking your girlfriend. Well — no more fantasizing.

Still stuffed in all the way, you reach up with your right hand and grab a handful of Monica’s hair, and with the left give her a quick and firm slap on each ass cheek.

You hear Monica moan, “Fuck yeah,” before you just begin to mercilessly pump your cock into her pussy as hard and fast as you can.

Somewhere in your mind you register that you can hear Rachel moaning and grunting as she gets herself off watching you pound her friend, but right now you only have eyes for Monica as you fuck her furiously, keeping your right hand full of her hair and using it like reins to pull back or move her, whichever you choose. Monica is almost speaking in tongues as multiple orgasms begin to hit her like waves.

You’re now coming to the brink of what feels like will be the most intense orgasm of your life and somehow you find a way to go even harder and faster and then finally, as you thrust as deep as you can possibly go, with one last tug on Monica’s hair and a “fuuuuuuuuuuuuck!!!” you release your load inside her. No longer pumping, you just push as hard and far as you can and her spasming pussy walls milk every last drop of semen from you.

For a moment you can’t move, can’t think. You just stay there, on your knees balls deep in Monica, both panting and shaking the force of your orgasms.

You’re shaken from your post orgasm haze when you feel the bed move. Rachel has now crawled onto the bed with the giant dildo in hand and a devilish look in her eye.

This is going to be a great day.

The End
