No

With one hand holding Jack's massive throbbing babymaker, Jessica grabs Jack's pillow. "Hey hey", he exclaims trying to be as quiet as possible.
Jessica swings the pillow through the air and hits Monica right at the back of the head.

"What the fuck is going on", is all that Jack could think, still in a delirium of being on the brink of cumming, his balls aching.
"Hey, Jessica! Look what I got.", and with that, the girl that Jack thinks is Jessica pulls his cock inside her waiting wet pussy and lowers herself onto him.
Before Jack could even realize what had just happened he found himself buried halfway into a woman, that looked like his lover but obviously isn't.

His cock didn't know the misery he had gotten into. The girl next to him wakes up slowly looking up to what appears to be her sister getting ready to drive Jacks full length into her waiting body. "What is going on?!", she mumbles coming out of a half-sleep, "Monica what are you doing!"

It is then that it hits Jack. The girl now firmly placed on his dick is Jessica's sister, who had passed out next to him. It is Monica that is now trying to bury Jack's cock deep inside her.

"I'm having a baby, just like you are, Jessica", and with that Jack feels a resistance against his cock head. Jack can't do anything. The immense tightness of Monica's virgin pussy forces him to go over the edge and he starts down the path of no return. Out of instinct, he pushes hard on Monica's thighs, tearing through her hymen with one swift motion lodging his pulsating crown at the entrance to Monica's cervix.

Like a glove, his cock sits ready to unleash a torrent of fertile sperm into Monica's waiting womb.

"No Monica you can't do this!", Jessica trying to push Monica off of Jacks cock. Failing to push her sister off her boyfriend, she desperately reaches for Jacks cock. Jessica tries to pull him out of her greedy sisters pussy but it is too late. All she can do is feel Jack's dick pulsing in her hand as the sperm that had been expectantly waiting for Jessica's pussy, is now racing into a womb it was never intended to be in. The crushing **** of Monica's vaginal muscles working Jack for every drop of cum and Jessica's **** pulling are too much for Jack. Jessica's attempts at preventing him from coming inside her sister are in vain.

The first jet of fertile white hot cum is racing from Jacks testicles through his groin into his shaft. The tight resistance of Jessica's grip makes it nearly impossible for it to pass by her grip, but then she can feel the first jet pass through her hand and into her sister's fertile body. Jack pushes as hard as he can on Monica trying to drive every bit of his hot cum into her womb and giving her his most precious gift.

Drained to the last drop, Jack realizes the betrayal he has just been part of. All he can see is Monica, Jessica's twin sister, grinning satisfied at him with his cock still lodged up at where her belly button was. "Thanks, daddy", she says, "or at least that's what you're going to be from now on."
