Warm to Hot

You know, it's biologically impossible to get bored of sex. Literally. You can get bored of doing specific sex acts, but the neurological response to sexual pleasure never actually goes away. A change in circumstances, or even just demeanour, can reignite any fire in the loins. This is useful, when you have multiple people to keep satisfied.

Marie and Rosie push me onto Marie's bed, matching grins on their faces. Now that I think about it, this'll be the first time we've had a threesome together, it's a strange realisation, seems like it'd be the first thing we did, but life's weird like that.

I don't spend too long contemplating it, as the girls begin to kiss each other, taking each other's clothes off, piece by piece, until only their bodies remain. I'm so focused that it takes me a second to realise that my jeans are being undone.

"Is it okay if..." Poppy begins, before gesturing towards my crotch. I can't help but smile and nod, as she removes my semi-hard penis from my underwear. "I can't get over how warm it is." She admits breathily.

"Why don't you give it a taste?" Marie asks, as Rosie massages her breasts from behind. "Trust me, it's indescribable."

Poppy looks from our cousin back to my slowly enlarging phallus. "You don't have to, if you don't- Argh." I'm cut off by the feeling of my sister's mouth enveloping my cock, making me swoon flat on the bed. Seeing sweet little Poppy's face getting penetrated is almost enough to make me come right there, but I hold off with all my strength, I did promise the others after all.

Her technique is... Well, she's doing her best, and honestly, the psychological element would probably be enough for most guys, but instead, after a few minutes, I place my hand under her chin and guide her face up to mine, kissing her thank you.

"Alright, Pops, back away or I'm not going to be able to resist you." Rosie coos, slapping our sister on the arse, drawing a surprised squeak before she retreats to the chair to witness the spectacle.

I attempt to sit up, but before I can, a knee lands to one side of my head, and before I can react, Marie is sat directly on my face. Not one to complain, I get to work with my tongue, trying to remember the spots and motions that she enjoyed last time. Simultaneously, I feel my clothes being taken off, then another mouth engulfing my prick, I can tell from the technique that it's not Poppy, seems like Rosie's been practising.

I can hear words being exchanged, but my cousin's thighs make effective earmuffs, and I can't tell what's being discussed, all I can see is a low angle view of Marie's tits, and I'm definitely happy with that view. Finally, my head is dismounted, and I hear an order from my former rider. "Fuck me from behind."

Again, I'm not one to complain, but I'm stunned into inaction as I see what the others were discussing, Poppy's taken the step of stripping down to just her underwear. It's just your usual beige bra and briefs, but the picture is one I can't help but admire... Until Rosie grabs my arm and pulls me into position behind Marie.

"You sure you don't want anal?" Rosie giggles, apparently aware of a joke I'm not.

"Fuck no, I barely got your finger in there, I'm not taking a cock that size up the arse." Marie dismisses it immediately. I would be disappointed, but as I enter Marie's soft and slick pussy, I can't find anything to be upset about.

I hear moans in surround sound, with Marie groaning as I enter her, and Poppy purring behind us, clearly enjoying the show. Rosie kisses me, before positioning herself to allow Marie to eat her out.

"You know, usually I wouldn't dream of coming between siblings..." Marie quips, until her tongue finds a more fun activity. Rosie looks like she wants to come up with a response, but the rush of pleasure dispatches any thought of retaliation. For my part, I keep fucking Marie, trying to find the right speed and pressure to drive her wild.

"Her pussy's something special, isn't it." Rosie pants. "So warm... So wet... So tasty... Are you enjoying fucking our cousin?" She asks, awaiting the dirty talk she loves so much.

I happily oblige. "It is, but then a slut like you would enjoy any pussy, wouldn't you?" I retort, making Rosie squeal with lust. "Say it. Say that you're a whore who'll fuck anyone, even your family." I order her, making Rosie erupt as her legs begin to shake.

"Oh fuck, I am. I'm such a slut, I want them all, I want to fuck all of them. I want to be their slutty bitch." My sister roars as she orgasms. It seems like Marie enjoyed the words as well, as her body begins to pulse and shudder.

With nothing left to hold back for, I release my come deep into Marie's pussy, before gently pulling out. My jizz begins to trickle down her thigh as we each take a breath. Sex may never get boring... But it never stops being a workout either.

"Aww, none left for me?" Rosie asks me, still trying to catch her breath. "Guess I'll take the leftovers." She adds, before positioning herself to lick my semen out of Marie's twat. I turn back to Poppy with a creeping realisation. She seems to have stopped touching herself, but the look of relief she usually has isn't on her face.

Everyone got off... Except her.
