Successful Experiment (Barry & Rebecca)

Taking advantage of the situation, Irons let go of the boobs just for his mouth to go straight to Rebecca's tits, sucking and spreading more of his "enhanced" saliva between her boobs. That made the moans reach a higher pitch, especially when his mouth went to one of her nipples, sucking and licking with such intensity that it was possible to hear the wet snap sounds from the mouth sucking. Rebecca had to keep biting her lip from all that groaning and moaning, it was only then, when Rebecca's body was filled with thick infected saliva, Irons decided to get off her body and started to take off her pants in a hurry.

This time all that strength wasn't needed, he knew Rebecca was his, she didn't even protested this time around, in fact, she was even opening her legs once the pants came off, showing her white panties, in the middle it was obvious how wet she was, the liquid made the panties transparent. Right after seeing that scene, Irons made sure to drop his pants to his knees, his cock popped out, white-ish almost like his own eyes, the purple veins all over his dick. Rebecca had a chance to look down while she was spreading the thick saliva on her own nipple, trance-like on how horny she was and realizing that her skin tit had a red-ish coloration from all the sucking, she also got a glimpse from his pulsating cock.

— Oh... you're so big... please be gentle...

Irons made sure to drag that panty to the side, just to reveal her small little pink pussy, it was shining from how much liquid she was leaking, and again, without wasting time, he guided his glans on the pussy lips, rubbing it up and down. It was almost like he didn't care how much time he took to get his prize, he knew she couldn't say no, on the contrary, with how much he teased her, she was getting more and more desperate to have him inside her, the monster look, the whole situation, was becoming a mere detail.

Rebecca kept moaning, rolling up her eyes and now it was her turn to grab her tits and grope as hard as she could, even stretching one of her nipples, especially when he started to rub the glans on her clit, beating the dickhead right in that little sensible spot to a point it would shake a little after each beat. She got so antsy with that, her body shivered all over, she even leaned her head backwards with a long moan.

— F-fuuuck... urrghh... just fuck me really hard, please.

It only took a couple seconds for her to change her mind, by being hesitant because of the cock size to begging for him to not have mercy on her, which he kinda did, at least for a moment. Irons guided his entire cock inside that pussy, even though she was really tight, the fact of how lubricated she was, it was easier, still, he had to put some force in his waist to make her pussy swallow the entire cock. Naturally, with each inch Rebecca was receiving, she screamed, louder and louder, while her pussy had to get used by that cock, widening and broadening those pussy lips, probably even Barry would hear those screams, wherever he was.

For the first time the monster Irons also joined in with his own grunts, still sinister ones, he even leaned back his head for a bit and closed his eyes, those creepy grunts is what made Rebecca regain a little bit of consciousness from the whole situation, she was getting fucked by a monster, but it was too late, too late to interrupt anything. Irons then started thrusting back and forth, again he was taking his time, barely using force or speed, just sliding his cock on that pussy while Rebecca moaned nonstop, with a expression mixed of pain and pleasure, tears naturally came out from her eyes, not knowing if it was because of that whole context or because how much she was filled with that cock.

It was quite clear that the virus didn't change Irons that much, from a sick perverted to a sick perverted monster, not much of a difference, aside from the eyes. After a minute or two with that rhythmic fuck he was imposing, Rebecca couldn't take it anymore and reached her orgasm, soaking Irons cock even more, as if his dick wasn't already enough. She screamed in pleasure, shivering during the whole orgasm and all of that didn't even fazed Irons, in fact he put his hands on her waist, pressing her body against the table once again, trying to calm down all that shivering and also giving him an easier time to keep fucking.

Since he had Rebecca pinned down, finally he started to fulfill Rebecca wishes, thrusting hard and rapidly, of course right after Rebecca's climax, so he took advantage on how sensitive she was down there and with how wide and wet Rebecca pussy was at that moment, used to his cock size and thickness, it was much easier to impose a faster rhythm. It was safe to say Rebecca's body was bouncing nonstop, her tits going up and down, she had no control, not even trying to grab the corner of the table was enough to stop all that bouncing, not the mention the continuous noises from Irons waist beating on Rebecca's skin and pussy.

It got to a point Rebecca's voice was starting to fail, raspy from all that moaning, groaning and screaming, she was starting to sweat as well from all that bouncing up and down, her pale skin glistening little by little, it was then that Irons talked in his monster voice, something simple, confirming that at least a little bit of consciousnesses he retained.

— More.... more....

All he was able to say, Rebecca looked confused and scared for the first time, not knowing what to say or do, she just kept screaming and moaning in pain from that intense fuck while her eyes rolled to the back of her head from time to time, just like her head going backwards and pressing it even more on the table by the rush of all those sensations. Irons kept getting frustrated, apparently by not having what he wanted, starting to use his waist strength to fuck Rebecca, one violent thrust after the other, ignoring much of the speed. Rebecca screamed in pain each time his cock would touch her deep with such force, mouth wide open, eyes closed.

— MOOOOREEEE... MOOOREEE....

It was Irons turn to scream, dripping more saliva from his mouth, acting like a real monster, one that saw pussy as the most valuable prize in life, and it really was. That bit of saliva dropped on her pussy, and it was instantaneous, Rebecca came once again, another orgasm, more shivering, to a point Rebecca was contorting on the table, it wasn't just one, multiple orgasms, one after the other. Irons apparently was satisfied, since he stopped with all that grunting, matter of fact, he came alongside Rebecca, filling that pussy with his sperm, relentless jets of sperm coming out of the glans while his whole cock was inside her.

Rebecca was so tired and her voice was failing so hard after those orgasms, it didn't come out, all she had left was to sigh and pant, sweating like a dirty pig, a dirty pig full of cum. When Irons finally relieved himself, he took his cock out of that pussy, making the cum come out immediately after, dripping on the table the excess of it, the rest was inside Rebecca, judging by how things worked with the virus, Rebecca was infected, bound to turn into those female zombie which surrounded Barry and her.

Irons left the room after that with his cock hanging out still dripping some liquid, leaving Rebecca on the table alone and filled with cum, like she had no more use for him, indeed she didn't, but he wasn't satisfied, like he said, he wanted more and even after cumming, his skin still remained the same, no degradation. Would he still consider his experiment as a failure if he was still alive after that? No one knows.
