Experiment gone wrong?

The two brunettes began stroking the well endowed members, pushing their bodies into the hot men they were falling for. Emily sighed feeling the man's lips on her breasts while Abella cooed and moaned feeling his hand grope her ass, "Oooo I want you so bad!"

The man under Abella groaned and kissed her cheek turning to the other guy, "So Tyler we aren't telling our wives we are fucking college chicks right?"

The other guy laughed, "Obviously Trent, calm down and enjoy yourself. Bet that other one can help you out."

Abella kissed Trent and bit his lip, "Oh you have a wife? That's so fucking hot!"

Trent smiled and turned to the third girl, a few years younger, "He's right come fucking suck my dick slut!"

The younger sister didn't need much more encouragement and kneeled on the side of the couch eagerly sticking the head in her mouth and lovingly sucking it. "Oh my god he tastes so fucking good!" Abella's bra fell behind the teen but she paid it no mind returning frantically to his cock, struggling to get more than a few inches in her mouth but savoring the rich taste of his male musk. Meanwhile Trent grunted and pulled Abella into him and aggressively teased her nipples with his mouth.

"It's sooooo fucking big and it tastes so good!" Kelly called out to Abella who bent over taking it from her mouth and tasting it. "Oh my god Kelly is right he tastes better than anything I've ever had! Dick is amazing!" Emily raised her eyebrow and before long she too was savoring the taste of her partner, the girls trying to work together and share but their desires clearly in the way and at times they became cock hogs.

Abella glanced behind her to see her once best friend worshiping her own cock with an ass that rivalled her new one in the air moaning lewly, "Holy shit Emily you and your sister look so fucking hot sucking dick!"

The female voice came back on, "You all can stop and return to your rooms if you wish. The experiment is over." The females voice changed to a different sound quality and was clearly arguing with the Doctor in a flushed and breathy voice, "You just doomed these poor people to acting like complete sex addicts! And what information did we get?"

The man chuckled, "It seems that those closer to the blast react quicker to stimuli. And more violently. Those girls didn't have curves like that until the stimuli activated whatever is inside of them. Not to mention Abella grew inches with her hair. The men's appendages almost doubled in size and length and they don't seem to care who each other are and have a renewed focus for reproduction. All with very minimal stimuli needed. This isn't just an Aphrodisiac Miss Bates, this is far more powerful and dangerous."

"Well I don't think they will be too cooperative in communicating with us anymore," the woman sighed. "Although I am taking this to our Mrs. Hallow to evaluate your unethical behavior."

The camera still showed the three women eagerly stripping their clothes and laying on their backs taking the mammoths between their legs, overwhelmed by the sensations. Meanwhile the left out Kelly pulled her clothes off as well and began fingering Abella, teasing her with dirty talk. Moans chorused through the talk of the disputing scientists and James was incredibly turned on at the show.

"There's no need to bring in Mrs. Hallow into this. I've dealt with everything already. May I call you Leia?"

"No."

"Too bad." The man continued, "Many labs have gathered some of the residual gas from the explosion and have been trying to determine its chemical formula. I on the other hand knew this was fast acting and wide spreading and took initiative. So I began to infect patients and monitored their decent."

"Patients?" she paused, "You mean you weren't testing for the gas..."

"I was administering it yes." He groaned. "I've been so fucking horny watching all these sluts take dick after dick, screaming to be filled and no longer feel empty. Wanting to be bred and fucked and pleased. So I gassed each patient and watched them reveal what perverted thoughts they hid deep inside. It's been so hot you can't deny that. Look at them!"

There was a pause and James watched Kelly and her sister both on their knees getting roughly fucked doggy while Abella watched adoringly. Two pairs of tits smacked together with every thrust while the girl's faces were completely overwhelmed by the intensity of the stretching and the pleasure it brought. They clearly had never been fucked like this. They slept with younger less experienced guys. Their screams were almost louder than the observers, cumming violently as their asses slapped against the hips of the bulls that were fucking their brains out.

"OHHH-Kelly!" Emily moaned, "It's so fucking hot taking these super big dicks with you. I love being your ughh-ughh-mmhmm slutty sister!"

"YES! God it's so biiiiig!" Kelly hissed back her tits loudly clapping together, "I love you so much! Can we fuck your boyfriend when we get home?"

"If we don't fuck Daddy first." Emily laughed briefly before flinching at the deep penetration.

Eventually the four moaned taking two loads as sisters and lovers and collapsed on each other kissing. Abella greedily sucking the two spent men off.

The three were spent but they softly began muttering, "More! More....want....cock...."
