"Are you sure about this?" your girlfriend asks softly.
You look at her. You look at your friend. "Yes."
She turns to him. She smiles. She seems nervous. So does he.
Then she kisses him. Her mouth opens. It's a hungry kiss. Their tongues meet.
Their obvious lust surprises you. It's as if they've been waiting for this moment, as if they want each other in a desperate fashion, as if they've been holding off simply because they didn't want to hurt your feelings by fucking each other behind your back.
His hands move to her waist. One crawls upwards and finds her breast. She moans into his mouth.
Her hand moves to his crotch. She finds his dick. It's hard. She strokes him through his jeans.
Their kiss gets fiercer. It's so obvious they desire each other in an overwhelming manner. You made the right choice in asking them to fuck while you watch.
He lifts her shirt over her head. He cups her breasts as they kiss.
You move closer. You unzip her skirt. You lower it along with her panties as they kiss. You caress the backs of her legs and gently finger her pussy for just a few seconds before stepping away once more.
Their kiss breaks. She looks up at him. "I'm so wet for you," she says.
"And I'm so fucking hard for you."
He takes his shirt off as she removes his jeans. His stiff cock is in her hand a moment later. She strokes him as they kiss. Their naked bodies press together. He holds her head in his hands as their tongues go on a wild, wondrous exploration.
He picks her up. He places her in your bed. He crawls between her legs. His cock brushes over her pussy lips. She guides him inside her. They don't require foreplay. They crave each other. There's no reason to do anything other than fuck.
You have a perfect view of your friend entering your girlfriend. You hear her moan as his cock slides deep into her.
"Fuck...fuck me," she says. "Fuck me!"
He fucks your girlfriend. In and out. In and out. You watch intently. You masturbate while doing so. Your cock has never been so hard. You've never been so turned on. You've never been so excited.
They cum together. He buries his dick inside her and fills her pussy with his load. It's a big load, too, and some of it begins to leak out of her almost immediately. Their moans fill the air. It was quick, but it was so fucking beautiful.
"Sorry that was so fast," he said.
"I came. I came hard, actually. And the night is young. There's more than enough time for you to fuck me again."
"Yeah?"
"Of course," she replies. "That was really good and I want it again."
They kiss. He stays inside her. He begins thrusting after a minute. His cock is still hard. You've never seen anything like it.
"Is this okay?" he asks. "I'm not soft so...can I fuck you again right now?"
"Of course," she replies before moaning. "Fuck...I can't believe how good your cock feels and I fucking love that you didn't even get soft, that you can already fuck me again. I've never been with a guy that can do that."
You feel a touch of inadequacy, but mostly you're turned on. Hard as a rock. Furiously masturbating.
The second time lasts longer. They fuck in missionary and girl on top. Her pussy is creamy from the cum already inside her. It's the most beautiful thing you've ever seen.
She looks at you while she's on top. "Thank you, baby," she says. "This feels so fucking good. So much better than I thought it would. I'm so glad you convinced me to let your friend fuck me."
She looks back at him before you can say a word. She leans down and they kiss. He grabs her ass and fucks his cock up into her. They remain in that particular configuration until they both cum for a second time.
The orgasms seem better. She's certainly quite a bit louder and her face is pure pleasure as she climaxes on your friend's cock for a second time.
Afterwards she rolls off of him and they cuddle. She spreads her legs a little and you stare between them.
"I think he likes the way your pussy looks," your friend says.
They both look at you. "I think you're right," she replies. "Baby, do you want to lick it a little?"
You look up from her pussy. "Really?"
She nods. "It seems fair that you get to do something fun, something that turns you on, and if you want to lick my pussy after your friend fucked it twice and came inside it twice, I see no reason you shouldn't be able to do that. Plus, if you really like it, you'll get to do it a whole lot more often in the future."
"What? I thought this was just a onetime thing."
She smiles. "I thought so too, but that was really good sex I just had and I know I'm going to want to do it again, so I'm afraid your friend and I will be fucking a whole lot more often in the future."
She kisses him deeply. Their tongues mingle. You crawl between her legs. You put your tongue inside her.
The die is cast. You might lose her, but it doesn't matter at this point. Your mind is awash in pleasure as you tongue fuck her sloppy, cum-filled pussy. This is bliss. Pure, perfect bliss.
If you get to keep doing this, it doesn't really matter if she breaks up with you. If you get to keep feeding on her cum-filled pussy, you'll be a very happy cuckold.
