Three hours later. . .
The bathroom of the gym stank to sweat, cum, and girl juice. Every inch of it was completely soaked from this marathon of constant fucking. Semen stains on the walls, puddles of sweat on the white tiles, and even some tiny drops of blood from the bandages that got loose after so much fucking.
Beside the handprints on the walls after he bent her over and fucked her from behind, he had had her pinned against the wall again, his cock buried balls deep inside her muscular pussy. Her legs were wrapped around his waist, putting to the test the boy's strength as he needed to hold that mountain of muscles while moving his hips.
"Fuck! Fuck me! Breed me like a worthless cum dump!" Barbara screamed, arching her back while her tits were bouncing with each thrust.
Plap, plap, plap.
"I think I am . . . going to die . . ." Leo managed to mutter, his whole body past the point of exhaustion since, even though they took small breaks to eat and drink, his stamina was on the negative. He had lost count of how many times he had cum inside her, ten? Twenty? The boy couldn't remember it. Every time he did, those fat nuts currently slapping against her muscular ass got refilled in an instant.
("Fuuuuuuuuuuck, this is amazing! I love him! I love him!") The Amazonian woman thought she was becoming a complete sex addict thanks to Leo's enhanced body and her own awakened desires.
"Coming! Fill me up! Fill your cumdumpster of a friend up with your mind-breaking jizz!" She yelled and crossed her legs with such strength around his waist that the boy heard a crunch, and that was nothing compared with the grip of that cunt.
He just let it loose, shooting another thick blast of white sap inside her already-filled womb.
"Fuuuuuuck! Yeah! Give me a good load!" Barbara yelled while squirting all over him again.
They stayed like that for a moment, connected as one while breathing each other's breaths, before Leo's cock finally softened just enough to slip out. Immediately, a flood of white poured out that gaping hole and joined the rest of his semen on the floor.
"Jesus Christ . . ." a new voice said from what they thought was the entrance of the gym.
After quickly getting dressed, they both headed to welcome the police officers that came to take the monster's corpse. Not even looking at the scene or even taking evidence, they were too overworked for that, and they needed to make sacrifices.
"So, it just jumped inside the place through that window?" One of the cops said, trying to ignore the stench of sex oozing from the two youngsters.
"Yeah . . . we had to kill it in self-defense . . ." Barbara muttered, hoping they only took the corpse and not her equipment as evidence.
"Tsk, its teeth are mutated, its DNA must be all fucked up; we may not even be able to tell if it was human or not," another officer added while looking at the cold monster corpse while a third one entered the place with a huge black body bag.
"I hope it wasn't a human . . ." Leo added, not wanting to imagine what would happen to his conscience if he accidentally killed an innocent man.
The first officer rolled his eyes, knowing full well how this kind of case ended. "Relax, boy, if we find anything about the case, we will let you two know," he reassured him that for these creatures, there was no such a thing as justice for better or worse.
Back in his apartment and after a shower, Leo needed a break from fucking and fighting; it was already getting late outside and the sun was setting, this day was over. After boarding up the windows of her gym to avoid looters, Barbara and the boy had to go their separate ways for now; she needed to do a lot of paperwork, and they knew if they stayed together they would fuck all night long instead of her spending the rest of the day fighting with the insurance.
"You are tired, you worked hard enough for a single day," Nigredo said as Leo came out of the shower, finally getting all the sweat and other fluid out of his body.
"Yeah . . . but maybe we should get outside tonight to help . . ." Leo muttered, looking at his old mask on the table even though his body was hurting from exhaustion already. Enhanced stamina didn't mean unlimited stamina.
Nigredo went silent for a second and began to rub his shoulders with her tentacles. "You already defeated a monster and saved someone; your good action of the day is done," she whispered beside his ear, giving him a good excuse to not get out of his apartment tonight.
Leo doubted for a second. "Yeah, you have a point. I didn't even fix my suit; if I had that, I could go out," he muttered. Too bad they spent the whole day fucking and training; the incident with Barbara didn't help either.
"You are right . . . we better just chill now and plan the mutation progress for the future," he finally added. Not going to fight crime didn't mean they could just mess around while the rest of the heroes were busy outside.
A lot of research on the internet and planning later. . .
It was already late at night, 10 pm to be exact. They had even made the cookies for the girls, and for Leo, he ate some of the prep meals he always had at hand. Rice, chicken, and broccoli are not really that good in the taste department, but they kept his stomach full.
Leo already felt a lot better, his legs weren't shaking, his muscles weren't sore, Nigredo made the recovery times a lot shorter than it should be. "Well, that is enough for today . . . we should . . ." he muttered while stretching his arms.
"Wanna fuck my ass?" The alien asked while getting in her humanoid form, hugging the boy from behind and squeezing his head between those massive black milktanks.
