Carolyn looked back at Jack with her eyes completely glazed over. She wasn't sure how long they had been fucking in the copy room at her fiance's office, but she knew Roger thought this was a great idea and treat for her. This somehow made her love him even more, which was really a weird thought to go along with the sensations of what Carolyn had decided was the perfect human cock obliterating her pussy beyond all recognition. She knew she would never be with another man that made her feel like this, even her fiance, whom she truly loved with all her heart.
You would think this would cause her to be unhappy with Roger going forward, slowly building a wedge between them that would lead to an unhappy marriage, ending in divorce in their middle years, that led to Carolyn becoming a cougar at the local college bars looking for some well hung stud to hopefully come somewhere close to the endless bliss Jack was giving her.
However, even knowing she would most likely never feel anything like this again, Carolyn didn't worry about that. She loved Roger, and his setting this up and giving her this gift of Jack's insatiable dick would lead to quite the opposite situation. Carolyn, after her brain fully recovered (several days later) to the endorphins being released into her brain at levels that few humans alive have experienced, would decide that her soon to be husband had earned, well, anything and everything.
Carolyn decided in the back of her head, while her conscious mind was destroyed and reborn again and again, that Roger was willing to give her anything she needed sexually. This led her to decide that she would be anything he wanted as well. Starting as early as the next morning, Carolyn would be the perfect little fuckdoll that selfless, loving Roger deserved. She would be his personal slutty cock slave. Anything he wished. Anything he desired, would be his. Head, pussy, anal, her hands, her tits. Anything. Hell, if he pointed out that one of her friends, or honestly, even one of her family (she had a flash of Roger fucking both her younger sisters and her much younger looking than she was mother) Carolyn would not only allow it, she'd try to arrange it. She might even join in if she found out the image of herself licking her sisters clit while he railed her cunt did it for him. Carolyn had decided, as she came again while riding Jack, that Roger would be the most well fucked man alive for the rest of her days for giving her this gift.
Jack's eyes rolled back in his head as he saw the fantasies of Carolyn licking her sisters pussy while her soon to be husband railed her college freshman body like a useless piece of meat, inside her head. Jack had been slowly working on Carolyn's mind while they fucked. He had figured out how to justify his usage of other men's women for his own pleasure. As he fucked her admittedly perfect late 20's body, he pushed gratitude for her fiance into her brain, connected to the ridiculous pleasure she was feeling.
He could have kept her. He knew it. He liked how she felt. Her pussy felt like one big muscle. When she came, the whole of her tunnel contracted like a cave in, locking his cock almost in place. He wouldn't have been able to move until she was finished cumming if she wasn't so, so wet. He wasn't even able to fully bury his cock into her body, though she did take more than he thought an "Unmodified" woman could. More than half his dick was stretching out her constantly tightening pussy.
But Jack thought he may have figured out how to get his morals to align with the new need to constantly fuck women all day, every day. If the woman didn't have a companion, he would have no issue destroying any sense of decency she had and making sure she was constantly thinking about, and occasionally visiting, Jack to get a "Tune up" on a regular basis.
