She needs a few minutes to warm up

Jenny and Greg bring their heads together and start kissing. Jenny closes her eyes to enjoy the kiss. Though she can’t see her cousin any more, she feels Penny’s eyes on her. It makes her feel excited. She never thought she would enjoy having an audience. If someone watching her kiss a guy is already so exciting, how much more fun would it be to have someone watch her fuck someone.
It doesn’t take long for Jenny to feel Greg’s hand on her hips. Seems like Greg is taking it slow. But Jenny doesn’t want it slow. She wants to corrupt her cousin as quickly as possible. She takes off Greg’s shirt, revealing his nude black chest, and throws it on the ground. Then she takes off her own shirt, exposing her white bra-covered boobs, and throws the shirt onto Greg’s.
When they go back to kissing Jenny feels Greg’s hand back on her hip. She places her hand onto his and guides it up her body towards her chest.
“Mmmh, yes.” Jenny thinks. “Show my cousin how white boobs should be handled.”
Once she successfully puts Greg’s hand on her boob Jenny lets her hands go to Greg’s pants and opens it up. Her white hands then slide into his pants and pull out an erect black dick for Penny to see. A quick glance at her cousin lets Jenny know Penny’s eyes are locked onto the dick.
“I wonder what she’s thinking while looking at his dick.” Jenny thinks. “Probably amazed at how big it is.”
She then starts sliding her hand up and down, giving the black dick a white blowjob for her cousin to see.

Penny had never seen people of different races kiss each other. Now her very own cousin is doing it right in front of her. Would she have dared it if their roles were reversed? Would kissing a black guy even be different from kissing a white guy? Her dad always told her to be careful of black guys. They were dangerous … apparently. But so far Greg had been very kind to her.
Then she sees Jenny take off Greg’s shit. He’s has a very sexy chest. But it is so dark. Then she sees Jenny’s shirt go off. She is so white next to him. She sees Jenny guide Greg’s hand to her chest and place it on her breast.
“Oh my, she really wants it.” Penny thinks.
Seeing her cousin act so bold makes Penny’s nipples harden.
Then Penny sees her cousin’s hands go to Greg’s crotch.
“She’s not going too … Oh my god! She just pulled out his dick.”
Penny’s eyes go wide and lock onto Greg’s dick. It is huge. The biggest dick she has ever seen. And her cousin has her hands on it. Playing with it like it is her toy. Well, Greg is her boyfriend, so it kind of is her toy. But Jesus, it’s so bit!
Penny clenches her thighs at the sight of Greg’s dick, including her pussy, and wished there was something inside her to grab on to. Penny imagines Greg’s dick inside her pussy and clenches her muscles again, and again, and again.
Then Greg takes off Jenny’s bra. He brings his mouth to her pink nipples and starts licking them in front of Penny.
Penny brings a hand to her chest and gently squeezes it. Her dad may not want her to engage in sex with a black guy, but seeing her cousin enjoy it makes her want to join.

When Jenny sees her cousin feeling herself up she smiles. Step two is done. Time to move to step three.
“You know.” Jenny says. “That’ll go much easier if you lose a few clothes.”
Penny blushes and says, “No, I …”
But Jenny interrupts her saying, “It’s quite easy, really.”
Jenny stands up and takes off her shoes, her socks, then her pants and even her panties. Greg also takes off the rest of his clothes. Then they go back at making out.

Watching her cousin strip like that really makes Penny a lot more comfortable about being nude. She’d have been too shy to get naked first, all alone. But not so much last. She starts taking off her clothes, all the while watching Jenny feel up Greg’s body while having her own body felt. When Penny is nude as well she sits back down. She puts one hand on her chest and brings the other between her legs, touching herself while watching her cousin.
