Joy had two fingers up Marc's ass and his cock half-way down her throat. This wasn't a special occasion, but it wasn't the sort of thing they did all the time either. Joy was on top of Marc, with her pussy right in his face, so he was definitely holding up his end of the bargain.
Marc loved eating Joy's pussy. He was good at it, as evidenced by Joy's cries of satisfaction every time he went to work. His skill at this particular endeavour was a defining aspect of his relationship with Joy.
She had never been with a man who was quite so adept at pulling an orgasm out of her. Most other men simply enjoyed themselves when they fucked Joy, and luckily for her, she enjoyed getting fucked.
While Joy usually settled for a pleasant sensation with these guys, the full body release that Marc regularly succeeded in giving her was unlike anything she had felt before. Her clit became a beacon that echoed ecstasy throughout the caverns of her physical and emotional selves.
The reverberations were almost painful, a confusing side-effect that would elicit sounds from Joy that sometimes worried Marc, for he hadn't been with many women. Or so he had told Joy. In fact, he was a virgin when they met. She suspected as much.
Marc's naivete is what drew Joy to him. Even if he was not experienced, so to speak, it was the experiences he continually gave Joy that truly overwhelmed her. It's why she felt obligated to reciprocate when he asked her, rather sheepishly, to shover her finger up his ass one day.
This caught Joy off guard. No man had ever made such a request of her. Many of them had asked if they could stick things in her ass, which didn't surprise her, but she never went for it, regardless of how she considered herself to be sexually adventurous.
That was the spirit in which Joy agreed to essentially fuck Marc up the butt. He was sitting on the couch in her apartment, about to get a blow job, as any man would enjoy, when he grabbed her right hand and gave her middle finger fellatio instead.
