Slightly more amused than angry...

"Well, well....." Jenna regards the two of you with a sneer, crossing her arms and cocking her hips, in an almost exaggerated pose of disapproval. "Have a nice shower, you two?"
"Jenna..." you start...but then you decide to keep your mouth shut.
"It's my fault, Jenna, babe." Zoe walks over to Jenna, with a pleading tone. "I was horny. I shouldn't have...not without you....It won't happen again without you there to approve it, I swear."
Jenna can't maintain the front any longer. Her smile is busting through as she shakes her head. "What am I going to do with you...you little fox." She grabs Zoe by the tit, mashing her nipple through her shirt with her finger and thumb. Her other hand slaps down hard on Zoe's ass, digging in deep.
"Oooh..." Zoe gasps. You just stand there with your jaw hanging.
"I'm pretty tired from all that shopping and house hunting..." Jenna kicks off her shoes, and brings Zoe over to the bed by her hair. "I was thinking maybe I might get a little afternoon delight from my loving husband..." she puts Zoe on her back on your bed. Zoe lets herself be guided easily, succumbing to Jenna's little bout of dominant behavior. Zoe's head is nearly off the end of the bed, and Jenna jams her thumb into your sister's mouth while gathering up her skirt to pull down her thong, letting it fall to the carpet and stepping out of it. Without a word, she climbs onto the bed over Zoe, and plants her crotch right over the punk girl's face.
"Mmmmm......but since you decided to be a horny slut...mmmm....I think i'll just take what I need from you, little Zoe." She flashes you a look. "I think ....ah....she needs some encouragement....don't you, James?"
You climb onto the bed from the other side. You aren't going to argue with Jenna, at least, not when she's in this mood. {if LucySexLvl > 1

} "Don't be shy,baby...." she flashes you a brief smile, as if to let you know: this is all for fun. She's probably irritated, but she's not angry. Well, that might be hoping for too much, but she probably won't be angry by the time your all through here. "I want to see what you get up to with your sister when I'm not around, you horny pig." Again...no heat in her words, and she's biting her lip now, and fondling her own tits with one hand while the other braces on Zoe's hip. "Take out your cock."
"Yes, ma'am." There's no argument from you. Despite your recent escapade, the situation in front of you has given you a new, throbbing erection. You pull down your boxerts and toss them aside as Jenna grabs Zoe's shorts and drags them down to her ankles, until they remain dangled around one foot. You lean over to kiss Jenna, and she moans into your mouth.
"Fuck her." You spear into your baby sister's cunt. It's soaked and yielding, and you hear a muffled groan of pleasure from somewhere beneath Jenna's thighs. "Harder...harder James....don't be gentle....be.. rrrrrroughhhh...ffff....." Jenna's eyes roll a little, and a wave hits her, causing her to inhale sharply and waver a little. "Little slut...'s....good......"
You obey your wife, and pound Zoe roughly. It's all so strangely hot. Jenna's hand snakes out to grip your neck and fish her fingers into your mouth, which you suckle on obediently. The pleasure that couldn't overcome your overstimulation before is now raw and bubbling in you, as if strengthened by Jenna's dominant streak.
"Are..you...going...to come...in her....for me....baby?" Her voice is a whine that sends you into a frenzy.
"I......"
"What do you think...Zoe..." she lifts up a little to give Zoe a chance to speak. Zoe takes the opportunity to only moan lewdly, face plastered with Jenna's juices and her own spit. "Should I let him fill you up?" she turns around, showing you her back as she settles back onto Zoe's face. "Eat my cunt, you little slut." Wow. Where is this coming from? Jenna's never been this domineering before. Perhaps...your explorations the night before unlocked something dormant in her.
For your part, you're happy to pound Zoe's pussy with wild abandon until you give a low throaty shout..." Cummmmmming...." and you suit your words by hilting home as you pump into your sister, while Jenna wails with pleasure, riding the girl's face.
You find yourself laying next to Jenna in the aftermath, cock shrinking, cum dribbling onto your leg, while she pants with ecstasy and exhaustion. For Zoe's part, she's almost mindlessly kissing Jenna's feet and rubbing her sore pussy.
"That was fun." Jenna breathes. "It's good to know I can make you two my bitches whenever I want!" she giggles. "Alright...I have to take a shower now. And I guess...Zoe should join me. She's a fucking mess, hahahah...." Jenna laughs, and so does Zoe. They stumble off into the bathroom, leaving you to contemplate the strange turns your life has taken these past few days.
