Cheater Cheater

Author's note: This story will, be written in the third person. I mistakenly marked it as first-person and I haven't yet figured out how to fix it.

Nichole couldn't help herself anymore, she moaned, loud and long as her pussy clenched on Jesse's thick black cock. She knew immediately that Dean would have heard it and would be on his way to see what had happened at any moment. Hopefully, her sister would be able to stall him enough that Jesse could cum inside of her before he got there.

About a month before

Nichole's sister Kristal had called her and asked a question, "How would you feel about having sex with my husband?"

Her brow furrowed, Nichole replied, "What? I don't think I heard you right,"

"Jesse and I have been talking about trying out sex with other people recently, and he mentioned that he's always been attracted to you,"

"You're not serious are you?"

"I kind of am. At first, I was pretty mad that he even suggested you, but the more I thought about it... Well I trust you, and you're happily married so it's unlikely that you'd try to steal him from me,"

"I don't think it's a good idea... Plus, there's no way Dean would be okay with it,"

"Talk to him about it if you want, we aren't in a hurry. I still want to shop around, if you know what I mean. Oh! Unless you just want to try a full swap!?"

Her jaw had dropped, the idea of Dean fucking her own sister seemed very wrong to her immediately, "No way. That makes me so uncomfortable,"

"Okay, okay. Just think it over for a while. Talk to Dean, see if it's something he'd be okay with,"

Nichole didn't say a word about the conversation to Dean. It wasn't fair, she knew that, but this seemed like a pivotal moment to her. It seemed like a decision that she needed to make herself. She knew in her heart that she loved Dean too much to share him, but she also knew that she'd never been with another man before. After Kristal asked the question it sparked a need in her, a need to try something new. She wanted to have her cake and eat it too, and she was aware of the irony.

As the days went on she had gone from contemplating it to fantasizing about it. Even as Dean fucked her from behind, his fist in her hair, his pelvis slapping against her ass. The days turned into weeks, as she fantasized, often cumming from the mental picture of Jesse fucking her. Eventually, Kristal sent her a few pictures of Jesse's cock with a single question mark as the text.

She just replied, "Okay. But, Dean can't know,"

Back to the present.

Dean heard Nichole shout as he finished installing shelves for Kristal. He'd wondered why Jesse hadn't done it himself but figured it was just because he didn't have the tools. "What was that?"

"What was what?" Kristal's face was bright red, "Is that shelf a little crooked?"

He looked then grabbed a level to check it, "It's fine, the bubble is right in the middle. See?"

She leaned in close, placing her hand on his leg as she looked at the level. She frowned as she realized missed her mark, "It looks a little low on that side," She adjusted the hand on his leg as she pointed, sliding up until she brushed against his flaccid cock.

He flinched a little but didn't move, "I... ah, it's fine, I promise," he gently grabbed her hand and stood, "I think I just heard Nichole,"

"Oh?" she slid her fingers between his, "I didn't hear th... I mean her. I didn't hear her,"

He raised an eyebrow, "What are you doing?"

"You just have such strong hands, it's very masculine,"

He pulls his hand away, blushing slightly, "I think I should go check on Nichole..."

She pulled him back tripping as she did and pulling him onto her, "Wait, Woah!"

From the other room, Jesse groans loudly as he pumps his massive load into Nichole, whose pussy spasms in orgasm once more at the feeling of hot cum splashed against her walls.

"Shit are you okay?" Dean lifted himself off of Kristal. He looked flustered as he knelt upright, noticing one of her breasts had slipped free of her tank top.

"I'm fine Dean,"

"Uhh... Your..." he pointed as he looked away, "You had a... that is, your... You, need to fix your shirt,"

The handle to the bathroom door turned and Nichole stepped out, flushed and out of breath.

Dean stood up immediately, a wet spot on his knee reminding him it had just been pressed firmly against his sister-in-law's cunt.

"What's going on out here," there was an edge to Nicole's voice. Jealousy rose in her even as she felt Jesse's cum drip down her thigh.

Kristal fixed her shirt, "Oh nothing. Dean thought he heard you call for help and was heading over to check on you, but ironically I tripped and took him down with me. Had a little wardrobe malfunction when I fell,"

"Uh, yeah, that," he helped Kristal up, "I'm done with the shelf, did we still want to go to dinner?"

The bathroom door opened again as Jesse stepped out, "I'm down for food, I just made plenty of room,"
