Ty wondered if he should really say what he had fantasized about so long. "Are-are you sure it's OK?" he asked.
"I know I'll want it," Eileen smiled.
Ty looked down at his athletic body, stripped naked by the beautiful young woman in front of him, and realized she was right. "I've..." He swallowed hard. "I've dreamed since I hit puberty about getting to fuck you. I've imagined kissing you, and pulling off your clothes and mine, and pressing you to the ground and pounding you until I filled you with my cum and bred you." He blushed deep red once he finished saying it, kind of ashamed of himself.
To Eileen's surprise, his confession had turned her on more than she already was. She looked down for a second at the erection in her hand, realizing what it must mean to Ty that she had been rubbing it. As she looked back at him, she smirked slyly. "How about you do that?" she purred.
Ty's jaw dropped. "You'd be OK with it?" he asked, surprised.
"You can change anything with your power, right?" Eileen pointed out. Ty nodded. "So, if we did this and then decided I don't want to be pregnant or we want to change things up, you can wish for it to change, right?" Ty nodded again. Eileen took her hand off his cock for a moment to reach for the hem of her nightgown, and pulled it up and off, throwing it to the floor.
Ty couldn't say a word as he saw Eileen's beautiful body. Her smooth, dark, bare flesh in front of him was intoxicating enough on its own without even considering her large, soft breasts. It felt like a dream to see her naked, but he knew he desperately wanted to follow through on this.
She gestured to him with a teasing smirk, and said, "Want to breed me?" Ty made a little shy murmur of 'mhm'. "Well, wish for me to ovulate," Eileen told him.
Ty willed the wish as soon as she asked for it, and a shiver went through Eileen as an egg emerged inside her and her cervix moved up, softened, moistened and seemed to open out a little. She hadn't felt this way in quite a while, but she was at her most fertile state.
She giggled as she noticed Ty had gotten a whiff of her pheromones, and leaned into him, giving him a very soft, lusty kiss. He kissed back and she felt him push her down with surprising force.
Ty's cock head slid over her moist lips, and he gasped as he felt her envelop him in her warm, wet passage. Having her wondrously soft body against his was the best sensation he'd ever felt, and almost instantly he felt masculine, animal instinct take over.
Eileen whimpered and moaned in pleasure as Ty's cock began to tirelessly thrust in and out of her, his hips gyrating above her and his balls slapping at her with every thrust. She felt her breasts bounce and her body shake with every thrust inside her, somehow able to tell she wasn't losing herself to the pleasure quite as much as the boy relinquishing his virginity to her.
When Ty's climax approached, he felt himself lose the ability to consciously move his hips, nature taking its course as he railed Eileen faster and faster. He felt like he could give her every drop of cum in his balls, and in his mind's eye he practically saw his sperm racing out of his body and into Eileen's. He heard himself grunt with satisfaction as at last, he hit his peak, squirting warm thick seed inside her.
Eileen felt his ejaculating cock rub along her G-spot while painting her insides with his semen, and she felt herself reach her own orgasm, her pussy walls clenching around him to milk him dry- not that he needed the help either to peak or for his seed to reach her depths.
Ty slowly opened his eyes again and saw Eileen gasping for air with a smile on her face just as big as his. He leaned into her and they kissed sloppily as they slowly recovered from the indescribable high of their fucking.
As their bodies became as close touching as is possible on the outside, Ty's essence had seeped into Eileen's womb, and soon his youthful, energetic sperm found her egg. Mimicking the instinctual vigor of the young man they had previously belonged to, they collectively bore through the outside of Eileen's egg and before long, one had managed to fertilize it.
