Crossing the line.

Jenna moans into Scott's mouth as she tugs at his belt. Scott's fingers continue to work her into a frenzy. She pulls open the belt, button and zipper, dragging his jeans down to his ankles. His dark grey briefs are concealing a prominent bulge.
"Are...you sure this is what you want, Jen?" Scott sounds hesitant. Perhaps he never expected things to go this far? For response, Jenna pushes him onto the bed, seated, and pulls his cock free of the cotton confines.
"Shut up." with those words, she begins to kiss and suckle on his cock. He lifts his ass off the bed, and she drags the briefs down to his ankles as well, and then he kicks jeans and underwear both off.
"I love my husband and his cock, Scotty, but I've been a kept woman for 20 years, since before I was old enough to vote. Sometimes, a girl just wants to sample something different..." she suits her words by gobbling on his cock so lewdly that he's reduced to curses in no time.
"Oh...holy fucking shit, baby. That's better than I even imagined."
You moisten your palm and start jerking off to the sight of your wayward wife polishing another man's knob.
Jenna's head pops up. "I don't want to lead you on, Scotty. This is a one-time thing. You understand?"
"Totally. Now stop fucking around and give me that pussy." Scott pulls Jenna up onto the bed, and positions her to straddle his face. You flinch back from the doorway instinctively, not wanting Jenna to spot you...not wanting this totally depraved spectacle to end. Watching her stray is so deliciously naughty that, against all odds, it's drowning out anger, shame or betrayal.
Soon, they're engaged in a very hot sixty-nine. Jenna repeatedly bottoms out on his cock, which you note with some satisfaction, is not quite as big as your own. You may be imagining it, but you think you saw disappointment on Jenna's face with how easy it was to deepthroat his cock.
"Oh...Jen I'm gonna blow..."
"Don't you dare, Scotty..." Jenna quickly dismounts and spins around, determined to go all the way and actually sit on Scotty's throbbing dick.
"Oh fuckk...." unfortunately for her, not only could Scotty not quite hold out, but Jenna's quick removal of her oral stimulation ruined his orgasm.
"Oh...Scotty...." she's not bothering to hide her disappointment as he spurts and dribbles his load helplessly, desperately trying to stroke it out and save his orgasm.
"Sorry, Jenna. Your mouth was too good..."
As she looks wistfully at Scotty's prick, you drink in the shame and disappointment on her face. You guess, once actually gone through with, her infidelity was less satisfying than she had expected.
"You....should clean yourself up, Scotty. I'm going downstairs to the pool. And remember...this never happened."
"Yeah....sure." Scotty's voice is disappointed too.
You quickly and quietly bail out, retreating to your office. Holy shit. You're filled with anger, and amusement, and arousal. Shame and a weird sense of satisfaction at her somewhat....truncated tryst also fills you. {if KaylaEdge = 1} it echoed, in an ironic way, your own little wayward encounter earlier that day, with Scotty's own sister. {elseif KaylaSub = 1} Perhaps, with this for leverage, you could explore an... "arrangement" involving Jenna and your new, submissive little pet.{else}
You are going to own that pussy later. You are determined on that.{endif}
You return to the pool to find Zoe, in sport panties and a white t-shirt, splashing and playing with Riley in the water. Allison is laid flat-out next to her mother on a beach chairs, both absorbing the sun.
"Well, did you find Jenna? Did she fall in the toilet or something?" You chuckle inwardly.
"She'll be out soon, I'm sure." Seconds later, Jenna appears on the porch. Not a hair is out of place, with no sign of her little fling. She joins the group amid adulation from Riley and Karen about her body and the sexy bikini. You watch her hungrily, holding your secret inside for now.
Scotty appears, wearing board shorts and his tight tank top, now. "Hey everybody. Shower's all set now." He takes the beer you offer, not noticing the look you give him. He's trying to hide it, but there's a seed of...disquiet on his face.
