This is turning you on too much

Something about the anonymity, the dirtiness of all this makes every attempt at a warning leave your lips as a whine of lust instead. The man looks over to you and gives you a conspiratorial thumbs up before starting to work the head of his manhood into the naughty nurse.

"Ungghhh! Oh... Oh! That's so... perfect. Wet and not too tight. I've got to savor this..." Not rushing things, he inserted his nozzle into her shaved pink pocket a centimeter at a time, waggling his hips side to side the entire time so she got to feel every angle of his engorged head sliding into her.

Felicity was still learning to practice the 'vocals' she figured she would need for her new career, so she started moaning in as slutty a voice as she could manage every time his penis probed deeper. She was already digging her fingernails into the arm of the couch. You were jealous of the girth she was getting to enjoy... and maybe, if you were honest with yourself, jealous of the potent semen she'd soon be getting a sample of.

Delightedly squeezing Felicity's tits through her bra, the man drew a sharp yelp from her when he thrust the last couple of inches with sudden speed and began bucking his hips back and forth. Soon he was slapping up against her pale, well-toned backside loud enough that the girl's moans were being drowned out.

"Ahhh! Ahhh! Oh yes, fuck yes, I can't wait to work with more dudes that're hung like you...!" Felicity gasped on, giving her head a lusty toss and sending her nurse's cap tumbling to the floor. You couldn't take it anymore and hiked up the edge of your dress, biting your lip and busily working your fingers into your own needy honeypot, adding to the basement's aroma of sex.

Anna went one step better and did a prancing fairy dance over to the happy couple. Leaning down and running her studded tongue over her lips naughtily, she smirked and bent down to **** Felicity's face in between the hefty tits that were about popping out of her green minidress. Felicity's glasses were fogged up with her breath and her moaning was muffled by copious amounts of cleavage.

Giving in to your fascination, you circled around behind where the fireman was still pumping away at her, building up to the moment you and he knew was coming but Felicity didn't, where he would hose down her burning hot cunt. You put your hands on his hips, feeling the thrusts and vicariously enjoying them, and leaned forward to enjoy the closest and most detailed view of a hard fuck that you'd ever seen. His balls were already tightening up, and you treated yourself to a rub and a squeeze of that straining wrinkled sack as he continued to slam himself into the slut masquerading as a nurse.

Knowing exactly what felt great, you split your attention to rub Felicity's clitty with your finger, drawing gratifying shivers from her every time you brushed it. The feeling of your fingertips getting smooshed between her labia and the man's testicles with every thrust made you giddy with excitement - you imagined you could feel the weight of the cum he had saved up, straining to explode forth into her steamy depths and deliver its precious cargo all the way to her womb. You can almost feel them making a last **** effort to produce as many sperm as possible for the unmissable opportunity to knock up this beautiful, intelligent yet blissfully naive young woman. Translating your enthusiasm into effort at pleasing the girl, it wasn't long until you brought Felicity to a gushing orgasm.

"Ungh... Nurse!" the guy groans desperately, clearly just barely clinging on. "I think I'm... ready... to give you my sperm sample!" he slides forward, driving so deep into her pussy that she arches her back involuntarily and clenches around him, putting him over the edge.

So this is how Tanya felt when she watched you. This evil, dominant feeling of power was so seductive, you couldn't do anything but watch and rub your thighs together wantonly. You could feel the cock fatefully throb once, twice, three times as he filled her up. Milky white batter was filling her - you knew because you heard Felicity give a sudden sharp, surprised yelp, wiggling her bottom back and forth and trying to pull away from him suddenly. Though you couldn't see her mouth behind the surgical mask you could see her eyes widen.

"A-HHH! Hot, something's hot! Uh... uh oh... is everything okay back there?" the slutty 'nurse' gasped out, panting and pulling her face from between Anna's melons.

The fireman rested his hands and chest on her back, collapsed against her for a few seconds, before he finally allowed her to push him away and backed his softening manhood out of her. The end of the condom was blown open, not having trapped a single drop of his seed. "Oh yeah babe, that was great... Hm, looks like the rubber broke though." He gave you a wink, giving you another surge of guilt-pleasure.

Felicity gasped and bent her head down upside down to look between her own legs. She squeezed nervously, and to the delight of you and the firefighter and her dismay, a pearly white droplet of cum beaded at the entrance of her pretty juice-dripping pussy. She hesitantly ran a finger over her shuddering feminine lips and felt the stickiness, at which point she suddenly leapt up off the couch, nearly tripping over her yanked down panties in the process. "Oh fuck, oh fuck, oh fuck!" she started gasping, wiping sweat from her forehead.

Behind her glasses, you could see in her eyes that she knew there were millions of a masked stranger's tadpoles swimming around in her depths, crowding around her cervix and swimming upstream deeper inside of her. "Damn it, damn it. You ass! Why didn't you check to make sure the condom was holding?!" she threw a couch cushion at the firefighter guy, who retreated and held up his hands defensively.

"Hey, I didn't feel anything wrong... That was really great though. You're the best fuck I've ever had. Don't worry about it though." he said suavely and nonchalantly. "Just stand up for a minute, you'll be alright, because of the heels."

Felicity, spreading her legs and trying to squeeze more out, looked up at him, dumbfounded. "...what?" she asked quizzically.

The hooded male guest just shrugged nonchalantly. "What? Oh, I guess you don't know - I was going to ask to go bare but I just went along with what you said... You don't need to worry about the cum because you're in high heels. Haven't you ever noticed how often the actresses in adult movies are always wearing high heels, even while they're having sex? It's because the angle that heels tilt your hips at makes it so you can't get pregnant even if some cum ends up inside."

You could barely stop your jaw from dropping at the brazenness of his lies. Even Anna seemed nervous and on the point of saying something, raising an index finger, but she didn't quite have the nerve to butt in.

Felicity, proving that she'd slept through sex ed, sounded hopeful when she replied. "R-really? Well, that would explain why everyone in the shoots I watched was wearing heels... I hope that's true. I think I'm going to go, um, clean myself up in the restroom anyway..."

Giving her one last squeeze on the bottom and a hug around the chest, the man pulled his speedo back on and walked back upstairs with a spring in his step while Felicity sought out a bathroom.

"Shouldn't we say something?" you meekly whisper to Anna.

She seems sympathetic... but just then, another pair comes down from the party upstairs. This time it's a guy in a Victorian waistcoat with a big fake beard, carrying in his arms an adorable, curvaceous, short-haired sorority co-ed called Kiki in his arms. She was wearing a simple 'alien costume' that amounted to an astonishingly tight black vinyl bodysuit that hugged her D-cup breasts and curves flatteringly with a large cutout exposing her ass and cunny, while she wore a cheap 'green alien' mask over her face kept on with an elastic string.

"Hey girls," the guy said, giving the alien-dressed girl's rump a proud smack with his open palm. "Room for two more down here?" She kicked her legs in his grasp and giggled flirtatiously.

"I leave it up to you," Anna whispers in your ear, uncertainly. "Maybe you should tell her, but I need to go find Tanya anyway. She'll be looking for you soon, I know." With that she waved politely to the other partygoers and skipped back upstairs.

There was an angel on your shoulder telling you to go warn Felicity after 'innocently overhearing' that she wasn't safe for the nonsense reasons that guy had told her. But then there was a devil - conceptualized in your mind as Tanya - telling you that you hadn't managed to rub yourself to orgasm yet, and watching another cute girl getting packed full of sperm was too good a voyeuristic opportunity to pass up.

Maybe you could even go a step beyond Anna and have this girl pleasure you while she was getting a risky fuck... After all, once Tanya pulled you into her plans for the weekend you'd no doubt be taking more of a risk than either of those two girls, so it was only fair you got to enjoy the show, right? Your lust made such twisted logic surprisingly palatable.
