Uhm … sure?

Tiffany has no idea what Jim is implying. Bust a nut? What is nutting? But she is on the verge of orgasm. All he needs to do is give her a few more strokes and she’ll be singing.
“Uh, sure, whatever, just make me cum.” Tiffany says.
Upon receiving her approval, Jim says, “Yes! Thank you, Tiff. I’m going to make you cum!”
Jim pounds Tiffany’s white pussy with a few more powerful strokes.
“Uh … Jim … I’m … cum … oooooh!” Tiffany moans as she hits her climax.
While his redheaded girlfriend orgasms Jim thrusts his dick all the way into her pussy and keeps it inside her.
In the middle of her orgasm Tiffany feels her boyfriend’s black dick pulse inside her and suddenly a warmth spreads through her loins. This feeling powers up her orgasm, granting her even more pleasure.
Tiffany writhes on Jim’s bed, her arms and legs flailing nearly uncontrollably.
Tiffany has never had an orgasm as strong as this. Not even when Jim gave her oral. It is so … overpowering. For a slight moment she feels she understands why some girls choose to become sluts.

After a while, when Tiffany calms down, she looks up and sees her boyfriend looking lovingly into her eyes.
“Seems like you had a good time.” Jim says.
Tiffany looks away and blushes while saying, “Uhm, yeah … Thank you.”
Jim smiles and backs away, pulling his dick out her pussy in the meantime.

The white teen girl looks between her legs and curiously studies her freshly fucked pussy.
“Jeezus.” Tiffany thinks. “My vagina looks like a gaping hole.”
Then she notices a whitish liquid coming out of it.
Tiffany takes some of it between her fingers and studies it. When she realizes what it is she is shocked.
“Oh god.” She says.
“Something wrong?” Jim asks.
“Uhm … no.” Tiffany says. “I just … never knew sex could be this great.”
Jim lays down on his bed next to Tiffany.
He looks at his girlfriend and says, “Sex is amazing, Tiff. And thank you for saving yourself for a black guy like me.”
“Oh?” Tiffany says and turns to lie on her side. “Why is that?”
“There is a saying amongst the black community.” Jim says as he motions towards his now lip dick. “Once you go black, you’re not going back.”
“I see.” Tiffany says. “So I went black just now?”
“Yes, Tiff” Jim replies. “You have been blacked.”
