She takes it like a champ

As the fucking continues, Greg starts thrusting faster and harder into Penny. His girlfriend, Jenny plays with herself, proud of herself for convincing her cousin to let herself get blacked. And Penny? She lies there and lets herself get taken advantage of by both her cousin and the black guy screwing her, all the while moaning herself towards an orgasm.
“Oh god. It’s going inside me. His whole dick is inside me. Do you see it, Jenny?” Penny moans loudly.
“I see it.” Jenny says while fingering her pussy. “Feels great, huh.”
“Yes! It feels so good. I feel so full. Ugh, fuck me, Greg.” Penny moans.
“Don’t worry, Penny.” Greg says. “I’ll give you the best fuck you’ll ever have.”
“That’s right, Penny.” Jenny continues. “You shouldn’t bother having sex with white dicks any more. It’ll never be as great as what you’re having right now.
“It won’t?” Penny asks.
“Of course not.” Jenny says. “It’s his huge size that makes it so great, and white dicks will never be as big as Greg’s. You’re better off only fucking black dicks from now on.”
“Then … do you think I … could come back for … another one?” Penny asks.
Jenny thinks a bit. Does she really want her cousin to regularly fuck her boyfriend? Then she gets an idea. She grins and bites her lower lip.
“Only if you say you love black dick.” Jenny says.
“Yes! Yes, I love them! Black dicks are the best!” Penny quickly says.
“Shit, Penny. You’re gona make me cum.” Greg groans.
“Pull out!” Penny quickly tells him.
“What?” Jenny asks. “I thought you said you love black dicks?”
“I do, but I don’t want one to shoot inside me.” Penny replies.
“Nope.” Jenny says. “If you really love black dicks you’d let them cum in you.”
“But …” Penny says as she turns to look at her cousin.
“Either you let him shoot in you or I’m not gona let you fuck my boyfriend again.” Jenny calmly says.
Penny looks back at her pussy. Greg’s dick is still pounding her, his black beast sliding in and out of her hole. She focusses on how much pleasure it’s making her feel. She could come back here and get a fuck from him any time she wants. All she has to do is let him shoot in her this one time.
“Well, it’s not like you can get pregnant from a guy shooting in you once. I mean, sperm is kind of overrated, right?” Penny thinks.
“Ok, fine! Shoot inside me!” Penny says.
Jenny gets a huge grin.
“Yes! It’s going to happen!” Jenny cheers in her thoughts and starts to really pound her pussy with her fingers.
Greg thrusts a few more times. Then he pulls out until just the tip is inside Penny’s pussy and then he unloads. His dick starts throbbing and he pumps his load into Penny.

When Penny feels his sperm flood inside her she spreads her eyes wide and moans, “Oooooh! He’s cumming! He’s shooting inside me! I can feel it! He’s shooting deep inside my pussy! Oh my god, I’m cumming too!”
“It’s happening!” Jenny cheers in her mind again. “My cousin is getting black bred! I made it happen! We’re both sluts for black cocks now!”
Jenny imagines her cousin in a few months.

She is pregnant and the baby inside her belly is black. It won’t have white skin like it’s mother. It won’t have blonde hair like it’s mother. It won’t even have Penny’s blue eyes. Jenny’s pussy then contracts around her own fingers and starts cumming at her cousin having her white genes bred out of existence.
“Yes! Oh, fuck yes!” Jenny moans loudly.

Twenty minutes later the blonde cousins leave Greg’s house. One of them has a whole lot of a black guy’s DNA inside her womb. The other already received some DNA from the same guy a couple days ago. Only time will tell whether or not it mixes with theirs.
