Jenny decides to lead by example

Jenny feels the only way she’s going to convince Penny to take a black dick up her pussy is by doing it herself first. That should take off the pressure and make Penny less stressed about it.
“Oh god.” Jenny moans while she brings both her hands to her pussy. “Seeing you give a blowjob makes me so horny, Penny. It makes me want to fuck.”
Penny looks up, letting Greg’s dick slip out of her mouth and says, “Really?”
“Yeah.” Jenny says, “Mind if I let my boyfriend screw me for a bit?”
“No, not at all.” Penny says, and gets off the bed.

Jenny and Greg switch positions. She lies on the bed, with her white legs spread wide open. Greg is in front of her, pointing his black dick to her hungry pussy. Penny sits in the bed behind Jenny. Her eyes are locked on both genitals on display in front of her. She watches how they meet. How the one opens effortlessly and the other disappears inside the former. Then she watches how her cousin gets fucked.

“Oh god. You feel so good inside me, Greg.” Jenny moans. “Your dick is so great.”
Last time he fucked her, she moaned to entice him to fuck her better. This time she’s moaning to convince Penny absolutely amazing it is to have a black dick inside her pussy.
“Oh yeah, just like that. Mmmmh, you make me feel so full.” Jenny continues moaning. “Oh, Penny, pull on my nipple.”

Penny reluctantly pulls her sight away from the conjoined genitals and searches for her cousin’s nipple closest to her to pinch it. Then she looks back at the cock and pussy doing their work out in front of her.

Penny’s thought are a ramble. Every thought gets followed by a new one.
“Oh my god, I am actually seeing sex being performed right in front of me. How is she taking it all in? Doesn’t it hurt? She does moan a lot so I guess it feels awesome. Would it feel that great for me too? No, I couldn’t let him inside me. What if he blows his load and gets me pregnant. But what if he pulls out before he shoots. I could find out how it feels to have a dick inside me. Not just any dick but a really big one. One that’s apparently really good at pleasuring a pussy.”

Jenny would love to let Greg plough her until she feels his load fill her up, but then there’s a chance he’ll go flaccid and Penny might miss out on getting blacked. If she wants Penny to get to step six she needs to cut this short.
“Oh, oh Greg. You’re making me cum. I’m gona cum on your huge cock. Ooooh my god.” Jenny moans loudly. Then she fakes an orgasm intended to make Penny believe Greg’s dick is so great it made her cum in a matter of minutes.
“You came already?” Penny asks with a confused look on her face.
“Oh. Well, I was already pretty horny.” Jenny excuses her early orgasm as she sits up on the bed. “But yeah, he already made me orgasm.”
“That is amazing.” Penny says while staring at Greg’s dick with newfound wonder.
Jenny puts her hands on Penny’s shoulders, grins and says, “Time for you to try.” Then pulls her cousin backwards.
Penny falls with her back onto the be, her legs falling on either side of her body. When she looks up she finds herself with her legs wide open and an erect black dick between them waving menacingly at her pussy.
“I … I … I … I don’t … think I’m ready.” Penny stutters.
Jenny lies herself next to her cousin and says, “How about he just pokes it a little. No penetration. Is that alright?”
“Well, it’s not like he can knock me up by rubbing his dick on the outside of my pussy.” Penny thinks.
“I … I … guess.” Penny replies.
Jenny then grabs Greg’s dick and moves it upside down. She guides the dark cockhead up and down Penny’s pale snatch.

“So close.” Jenny thinks. “I’m almost there.”
“Ooooh,” Penny moans softly. “That feels … kinda good.
Jenny then aims the tip right in front of Penny’s vagina and circles it around to tease the edges.
She waits until Penny moans again then suggests, “How about you let just the tip inside. It’ll feel so great and it’s not like he’d actually be fucking you.”
“If it’s just the tip … I guess he could easily pull out instead of impregnating me.” Penny thinks.
“Ok then.” Penny says, “But just the tip.”
“Yes!!!” Jenny cheers inside her thoughts.
Jenny holds the black dick inside her hand still, keeping it right in front of her cousin’s vagina. Jenny stares at the black dick in front of her about to go inside her. Greg then slowly pushes forward, spreading out Penny’s hole until his cockhead is inside her pussy.
“Hoooo.” Penny mewls as she feels her pussy stretch for the first time.
Jenny lets go of Greg’s dick and brings her hand to her pussy. Greg starts moving his hips back and forth, sliding his cockhead in and out of Penny’s pussy. Penny looks up and stares into the eyes of the man that is fucking her. Jenny plays with her pussy while looking at her cousin who is now getting blacked.

After a couple more thrusts Jenny looks at Greg and mouths, “More.” To him.
Greg gets the message and the next time he pushes into Penny he does a little more than just the tip. Penny doesn’t seem to notice.
A few thrusts later, Jenny again mouths, “More.” To her boyfriend.
Again Greg slides a bit more of his dick inside Penny. Penny doesn’t object to it, she just moans more frequently.
Five thrusts later Jenny mouths her message again. Greg obeys, getting more of his dick inside his girlfriend’s cousin. By now he is fucking Penny with half his dick. Penny doesn’t protest to it, she just moans more loudly.
Another couple thrusts later Greg doesn’t even need Jenny to order him. He pushes a bit more of his dick inside Penny and the girl doesn’t bring up he is far beyond using just the tip.
A bit later Greg is thrusting the entire length of his dick into Penny. The girl never once objected and is now moaning loudly, enjoy the huge black dick going all the way inside her pussy.
