Dirty flirty Karen....

"Thanks... just trying to do the...." you trail off as you look at Karen. In her new position on the bed, her dress has ridden up a bit, enough for you to see that she is not wearing panties.
"Karen..!" You spin around. "I can see your.... you know!"
Karen giggles. "Oops. How did that happen?" You hear her shift around a little. "I fixed it, James, you can look."
You turn back, "I think you may have had too mu...." when you turn back, she's pulled her dress up to her waist, and she's got a finger planted in her ginger cunt.
"Karen...!"
"Oh come on James... don't tell me you never wanted to see it..." her voice is thick from drink, and she's clearly as horny as a goat.
"Karen what the hell... you're my sister in-law." You squeeze your eyes shut.
"You're no fun..." Karen whines. "Jenna's always going on and on about that big cock of yours..."
You open your eyes to stare at her with incredulity.
"Come on.... let me see it..." she starts working her pussy.
"Karen I can't..."
"Just a quick look... I can see that it wants to come out..." she points, and you look down to see the tent forming against your shorts.
Without really knowing what you're doing, you unbutton your shorts, reaching in to pull your cock free. Maybe if you just satisfy her curiosity, she'll cut it out.
"Come over here.... I can't see it from all the way over there...." she whines.
"Jesus Christ, Karen..." you reluctantly approach to within reach of the horny woman.
"Ooh...baby.... she wasn't lying..." she reaches out to take hold of your cock, and you grit your teeth as she bounces it on her palm.
"Satisfied?" You growl.
"Oh, don't be such a prude, James. Jenna cock blocked me at the club... haha... does that even count when it's on the other end? I almost had two big dicks in me.... I need something..."
"Well, you can't have this..." you put your cock away, but your head is swimming as hormones and pheromones course through your system, with not regard for little things like wedding vows or family relationships.
"Booo...." she starts jilling harder, squeezing her eyes shut. "I bet it would feel so good in me..."
"Why would you want to do that to Jenna?"
"Oh, she wouldn't have to know... ah ah ah!!!" Karen shudders and shakes, hitting a cresting orgasm in front of you. The sight is quite erotic.
"Karen... you're drunk. I think you should sleep it off and calm yourself."
Karen smiles lazily, pulling her dress back down. "What a boy scout..."
"Not really." you laugh.
"Well... it's going to be a long two weeks, bubba. I'll see you around..."
