Cam was in bed, laying shirtless on his back with his hands behind his head. His wife Gabby had told him once that she was always a fan of being able to see his armpit hair, that it was one of his male sex characteristics that really turned her on.
Earlier, while they were watching Netflix, she asked when they could have a baby, so he knew his wife was itching to mate with him and wanted to get impregnated by him. He was actively showing it off to her, presenting his masculinity, indicating non-verbally to her that he was in his prime and matured. The animal within him instructed him to show off to her, letting her see his vitality and well-developed maleness that allowed him to have large bushes of hair beneath his arms, which gave off his male scent.
The effect of his pheromones was nearly immediate. Gabby's hand slid across the sheet under the covers, as she got into bed, and reached between his legs for his penis. Cam slept naked, so it was an easy exploration and discovery. Her face brushed against his, "I want your sperm, Cam."
"Oh, yeah?"
"Yes," she exhaled in his ear. She was clearly in heat.
Cam kept his hands behind his head, giving Gabby a visual of the brown jungle of hair in his armpits, as her leg slid over his abdomen to mount him. He figured too that the slight body odor wafting from his pits would encourage her pussy to lubricate itself more and open wider to accept his organ, sensing the feral male that he was, her body instructing itself to breed with him.
Cam felt his biology working. Blood rushed to his cock, as it started to grow erect between his legs as his wife got on top of him. "You want my fertile semen, Gab?"
"So badly," she moaned to him. "I want you to knock me up." Cam's cock swelled thicker and firmer hearing her say that, readying itself to plunge into her. It was preparing to fertilize her ovulating egg the way it was meant to. He was able to since he had finished puberty and was a 24-year-old man. He felt a rush of masculine energy in his chest, bordering pride and power, knowing that his orgasm had the ability to populate the globe. It was a bit energizing too, knowing they would not be using protection. He would be inside his wife raw, trying to create offspring with her. He was ready for it. This was his purpose, and his stiffening erection was proof of his readiness to fuck his wife's fertile cunt.
Cam could feel the lips of her vagina brushing against his hairy torso as she straddle him. Spots of her wetness dotted his abdomen as her pussy leaked onto him. Her body was getting ready to accept his shaft into her. Cam smiled, happy to see her biology working as well, happy with himself in having chosen a mate whose body was just as ready as his for the act of procreation.
Although she was already naked from the waist down, Gabby was still wearing a white t-shirt. She wasn't wearing a bra, but Cam wanted her completely naked, like they would be in the wild. "Get this off." He ran his palms against her waist, sliding them up her torso to help her strip. She followed his order and grabbed at the edge of her shirt to pull it off. He watched his wife lift her arms and remove it, allowing her plump breasts to plop out from underneath. The blood pushed tighter against the inside of his dick, packing tightly into the length of his cock, as he eyed her tits. They swayed melodically as she leaned over to drop her shirt on the floor. They were exposed and his to admire freely.
Cam assessed their size and inflated quality, happy to see that her nipples were hard. He reached up and placed his large hands on each of her boobs, somehow feeling himself growing even more stiff between his legs. He was ready to fucking slam her cunt with his cock. But foreplay came first, to make his wife's vagina insatiate for his maleness.
"Oh fuck," she squealed to him. He grabbed her breasts firmly and deliberately with his big hands, working their soft, malleable plumpness the way a baker works dough. Each one of them felt heavy in his palms, cradled gently in his grip. He focused the movement of his fingertips to her areolas, caressing her nipples as they grew harder and more protruded. She moaned again in response, as his hands worked her swelling breast tissue.
Cam was glad to not only have such an attractive mate, but one he knew would successfully bare his offspring, eventually nursing them with these sizeable breasts. Again, the animal of his body erupted in pride, thinking of Gabby baring his progeny and seeing her breastfeed them. As the male and father, it was his duty to ensure her body was adequate for child rearing before impregnating her.
He sat up and grabbed her left breast in his hand. He placed his lips over her nipple, sucking it into his mouth. She immediately quivered with pleasure. "Oh, god yeah, Cam." His lips sealed around it. Her stiffening nipple pranced over his tongue with each flick he made, as he teased it playfully. She quivered again, pussy drooling on him more. Cam pressed his lips more firmly against the skin of her boob and sucked on her nipple, as if nursing. She ran her fingers through his hair, pushing his mouth into her chest by the back of his head. Gabby wasn't making any milk, otherwise he would have gotten a throat full, but he was satisfied that she would have encouraged feeding by their child. He released the suction, hearing the slightest 'pop' as her nipple fell from his mouth. Her maternal instinct was strong.
"You like that," he asked her, placing his hands on her waist.
"You have no idea," she exhaled. Cam glanced between her legs and was glad to see a larger area of wetness on his torso. She was turned on and actively leaking, prepared to lubricate his cock to enter into her, for breeding.
Cam wrapped his thick, hairy arm around Gabby's waist and slowly rotated her beneath him, easing her onto her back. He had read somewhere that the missionary position had the highest rate of producing a boy. That's exactly what he wanted her to carry in her womb, a male to pass on their Y chromosome.
He leaned down and kissed Gabby's lips, slowing working his way to her neck, hearing her soft exhales of pleasure as he did. His scruff scratched her gently with each brush of his lips. At the sound of the bristling, her moans kept coming forth, no doubt causing more precum to seep from her cunt.
Gabby reached down and wrapped her fingers around the head of his swollen, stiff penis, pointing straight out from between his legs. Like her, he was aroused and turned on. He had a full erection, engorged and pulsing to fuck her.
"Jesus," she announced, as if something was wrong.
Cam stopped kissing her. "What is it?" He followed her eyes down between his legs. Her fingers were webbed with thick webs of his precum. He chuckled. "I'm so ready to knock you up."
"That's so fucking hot."
"You like how much I precum for you?"
"I fucking love it, Cam. Your balls must be so full of sperm." She reached farther and cupped the two dangling testicles encased in his hairy sack of skin. "Exactly what I need to get pregnant. Can't have a baby without your cum."
"I'm locked and loaded, Gab."
"When was the last time you ejaculated," she asked, fondling his balls.
"Yesterday morning in the shower. But I make a shit ton of cum. Those two bad boys you're holding feel heavy in there."
"God, I can't wait for you to unload it all inside of me."
