Kevin looked down at Julie, his slut. Wait a minute, he thought. She's my girlfriend. Not my slut. But the more she sucked his dick, the more he started to think of her in that way. And then with a jerk and a contented sigh, he cummed into her mouth. And she swallowed it, happily. Yep, she's definitely my slut.
Julie licked her lips, trying to get at any semen that she missed, then swallowed that too. Then she looked up at Kevin with eyes of lust and sort of emptiness, like she was some sort of an air-headed bimbo. This was definitely not his Julie. This was an insatiable slut with only one thing on her mind: sex.
But how had this happened?
That question seemed to drift from his mind, though, as he felt Julie reposition herself in front of him. Then she pulled Kevin into her, his penis easily penetrating her pussy. It was so wet. Oh god, Kevin thought. I can't believe this is actually happening.
