She's smugly delighted to see you following her path

It didn't take you long at all to let go of your last inhibitions and leave the naughty nurse and her potential egg to their fate in the restroom and jump in. All it took was a few flirty waves and flaunts of your chest and the waistcoated man hooked an arm around your waist and pulled you onto the couch next to him and the busty girl in the crotchless bodysuit in his lap.

You saw almost immediately that her uncovered light-brown pussylips were leaving a wet spot on the crotch of the man's pants as she ground on top of him. You hugged your arms around her chest and felt the slippery, squeaky surface of her squeezable breasts as you groped her forcefully. Lust driving you onward, knowing that Tanya wouldn't care that you were putting your hands on an anonymous girl even if she knew, you pulled yourself closer and closer against her, burying the guy on the bottom under the combined weight of your cute body and the even more vivacious curves of Kiki.

You put your hand in Kiki's short black bowl-cut hair, and ran your tongue up and down her neck. "Ooooh, I can tell you're one of the wilder girls here, Princess," Kiki said, betraying a hint of nervousness. You were sure this would be her first three-way. "Um... what do you think would feel good...?"

Thinking for a moment, at first you wanted to do the noble thing and try to defuse the situation (for Kiki's sake) with a double blowjob. You whispered that idea to the other girl and she nodded - you could tell she was blushing even behind her fully covering mask.

So as to go along with the rules, the guy offered with a smirk to close his eyes while you went to work on him, and Kiki momentarily pulled her mask up onto the top of her head, the two of you pulling down the guy's trousers and freed his big, curved spear. Because of his heavy wool clothing it smelled musky and sweaty as you put your lips to it. You and Kiki slid your tongues and lips up and down each side of the shaft and even took a turn awkwardly pressing it between your boobs. The enterprising guy took this opportunity to slide his hand down the small of your back and start groping and rubbing the spot between your thighs, and even your ass-hole, with his fingers. When you looked up from the blowjob you could see Kiki was getting the same treatment.

But then the request that both excited and frightened you came, sending a shiver up your spine: The man rested his hands on you and Kiki's shoulders and grunted in excitement. "Come on, ladies. Don't you want to try riding me?" He pulled out a condom wrapper from his jacket pocket, anticipating Kiki's objection. It was the same brand Tanya had been tampered with, of course. Kiki giggled and started stroking his shaft, opening the package and putting it onto the straining cock already dribbling pre-come from the tip.

A minute more warmup and some re-positioning later you were straddling the man's head as he lay lengthwise on the couch. Pulling the fake beard down and out of the way, you gave a satisfied sigh as you pushed your crotch down on his face, aggressively forcing your pink, pierced, tattooed slit down on his mouth. You could hear a little gasp as he got close enough to make our the tattoo you had right on your bikini area, seeing the image of the sperm crowding around an egg silhouetted by the heart. But before he could remark on it any, his words were replaced by a wordless groan as Kiki, facing you and with her mask back in place, started easing her slippery cunt down onto that straining cockhead.

The basement was soon alive with the sound of a tongue slurping your sopping cunt and Kiki's vinyl-clad ass bouncing up and down against the hips of that tongue's owner, going so hard against him so quickly that you could hear the burble of escaping air when she sat down hard on him and let him go all the way inside her.

With the two of you all dressed up in your slutty costumes, bouncing on both sides of the lucky guy laying down on the couch, the scene could only be described as comical - a princess and a (not so) little green (wo)man riding a victorian gentleman and reaching forward to fondle one another's chests. Kiki didn't know how to rub and just held onto your bouncing tits like handles but that was plenty, along with the tongue flicking over your clit, to bring you closer and closer to the edge.

Feeling brazen now, you actually leaned very far forward to take hold of Kiki's vinyl covered ass cheeks and start bouncing her up and down on the cock underneath her even faster. You regrettably couldn't see much of it but the *schlick schlick schlick* of his fat shaft plunging into her folds again and again was exciting enough in and of itself.

Taking a break from tonguing your slit, the man - breathing very heavily now - started mumbling something loudly, though your thighs and pussy muffled most of what he was trying to say. Thoughts of splashing seed had been driving you wild with lust for a good half hour at this point, and even without his tongue cleaning you out, you could feel yourself sitting at the edge as you imagined a thick wad of the anonymous man's swimmers welling up inside his shaft and getting ready to splash into her depths. You imagined the worry on the faces of the two costumed girls you'd watched getting fucked when they noticed their periods were late, how they'd think back to this lusty night and be fascinated anew by the memory of the pleasure, just like you were whenever you thought back to Tanya introducing you to the risky side.

"I think..." you panted to Kiki, who was sitting right on his lap, with her ass resting against his hips and waggling herself from side to side to let his pubes rub up against her clit to get herself off, "that he just said he felt the condom break.

"...huh?" Kiki said, lost in her own pleasure and slowly snapping out of it like a dream. "Ohh... I..." she wailed in a high-pitched voice, caught between her desire for pleasure and her rationality. "...need to get up-"

As if some deep-rooted, breeding-obsessed part of the man's lizard brain realized it was about to lose its chance to attempt breeding, Kiki and your sex partner groaned into your inner thighs again and bucked sharply underneath you, gripping Kiki's hips. You heard the sharp yelp of Kiki feeling a fountain of potent semen blast up into her before she could pull herself forward off of his twitching cock.

Raising up slightly you vibrated your finger rapidly over your clitoris, just as lost to the demands of pleasure. "UNGHH, yes!!" you shriek as pleasure explodes through your senses and hot juice starts to dribble down around your fingers. Your thighs quivered involuntarily as you rolled off the exhausted man's face and down onto the carpet.

The sight of Kiki's reaction to your words, torn between two competing impulses, had been a new thrill for you. You couldn't help continuing to softly rub yourself as you watched her hop up off the couch, gasping and whining as she fingered herself, still breathless from coming herself (thanks, in no small part, to your expert flicking and massaging of her breasts). As the guy in the fake beard stood up, Kiki weakly punched him in the back as he made a hurried apology.

"It was my fault..." you said eventually, swallowing. "Er, I mean... because I was muffling his mouth, he couldn't warn you in time.

Rolling her eyes and sighing in annoyance, Kiki made a 'talk to the hand' gesture to you. Then she started jumping up and down as high as she could, feet thumping loudly against the floor with each landing, trying to get at least some of those millions of sperm to drip back out of her. Noticing you watching, the asian girl gave you a dirty look, so you smiled awkwardly and scurried back up the stairs after the guy.

Waiting at the top of the landing were Annabelle and Tanya, the latter looking especially pleased, her bright blue eyes beaming at you as if you were a present on Christmas morning. "So," she says effervescently, "you must realize I couldn't help peeping down there a few times... guess you weren't able to stop either of those two inseminations, huh Princess? Oh you are just the most perfect, precious party Princess ever." she stammered out in a joyful, alliterative squeal. Before you could say anything back she was pushing that big soft chest of hers up against you and planting a kiss on your lips.

"Now... from the smell, you've already gotten to come and I haven't. As happy as I am for you discovering this kind of fun, I think that's a little bit unfair, don't you? So follow me. No more stalling, it's your turn to roll the dice. Out in the dining room we're going to be putting on a fantasy-themed play. I was too busy with party prep to write any dialogue, so it's going to be just fucking, and lots of it."

"There will be a fairy of fertility," she pointed to Annabelle, who giggled, "a naughty witch, a sexy knight, a voluptuous dragon-lady," she pointed to herself with a proud twitch of her nose, "and, of course, a pure-hearted and beautiful princess... all being ravished by horny beasts. Of course, when I announce to them that I know for a fact that you're at your most fertile time of month and have been off birth control for weeks now I wouldn't be surprised if you were their first choice." she purred lustily and gave one of your pierced nipples a little tweak before wrapping a hand around your waist and leading you to the next room and the main event, where Vanessa and Willow were already dancing erotically to the cheers of the other guests...
