Leonard asks penny to sleep with a donor for some science thing, she's not dumb but has no clue what it is or does no matter how many times its explained.

She's not thrilled to say the least, she says this is just between some friends not pimping out your hot wife now.

He sees nothing different and since she really can't explain the two agrees.

But says if is some old guy with a shriveled up penis she's fucking as many guys as possible in front of him, bigger the better.

She goes to the door and is greeted by a white woman not much older than her, oh god please don't let her husband be some old sugar daddy is her husband or God his daughter.

She walks in and he's around the same age as the wife, she'd guess 40ish young, he's good looking tall and black, she better watch it our her panties will be wet.

"Our"

"Oh did your husband not explain?"

"I didn't even know the age I was meeting."

"We'd like to try a three some, we saw you with dr hofstader and first were shocked you were married and he came to me about a project and I said I might find it if I borrowed you, eventually he agreed." The husband said.

Hmm.

"Well I'm here and horny so why not."

She slips out of her clothes and only in a bra and panties, the wife goes down on her crotch and the husband sucks on her bra clad tits. Holy shit I'm going to have multiple orgasms for sure and not long she cums.

She then goes to her knees and pulls the guy out, woah as she takes his size in her hand before she puts him in her mouth and sucks him off. Based off the movies I guess it's true about black men.

She lays on the bed and husband eats her out while the wife stands up with her pussy to penny's face to eat out, she's not going to lie the wife has a nice body and pussy is as well, as she licks it up and down making the wife moan penny places both hands on the wife's thighs to get a better grip and brings it closer as she licks with more force bring the wife close.

Not long both women cry out.

Penny lays down and wife kisses her lips before they trail down her body until they get to the center and starts to eat out penny after several minutes she brings penny to an orgasm.

Penny lips trail down the wife's body until it get to the center and then she goes down on the wife after licking and sucking for several minutes until the woman cums.

While penny is doing this the husband slides in and starts pounding. Catching penny off guard at first.

"You have a nice ass penny"

He just watches as her white ass just bounces on his black dick, while she eats out his wife.

Before long her slaps both cheeks of penny's ass making her cry out more. He speeds up and starts to really fuck her and long both are cuming and not long the wife cries out by penny's tongue. As both women cum.

The husband then turns penny over and slides in, he starts pounding away, good thing I slept with Sheldon recently. She then wraps her legs and arms around him to get a better feel as he digs in deeper as she throws her head back until she cums and before long he cums.

"Holy shit yes!"

"Fuck me with that black Dick."

Before long he cums as does she.

After catching their breathe Penny gets up and leaves.

"Oh your husband most certainly will be getting funding, but if you want to stop by don't hesitate."

"I'll tell him, I just might take you on the offer."
