Once they broke off their kiss, Eileen asked, "Sure it's OK if I mate you?"
"Please do," Ty smiled.
A warm, dark hand ran along Ty's supple curves. "I'm so glad you were OK with emasculating yourself and turning into my perfect baby factory," he grinned.
"Yeah?" Ty replied. "Well, I'M glad you asked me to turn you into a handsome stud I can get bred by over and over."
They kissed again, and their hearts raced as their bodies pressed tightly together, Ty's breasts slinking against Eileen's firm chest and his manhood brushing along her stomach, his sac touching her flat mound. With one fluid, instinctual motion, Eileen picked himself up on his hands, slid his penis down until its throbbing head ran over Ty's moist vaginal lips, and thrust inside.
Ty wrapped her arms and legs tightly around her lover and moaned lustily into his ear as she felt him start to move in and out of her. His larger muscles felt overwhelmingly strong to her and his rough skin touching her smoother flesh made for an intoxicating contrast- even after having sex with this DILF multiple times, she still felt like she was discovering new things about her altered sex.
On the other hand, Eileen was still succumbing to the intense desire that comes with masculine arousal, his hips pounding him in and out of Ty's tight slit as fast as he could while her moans pushed him closer to his peak. The warmth of her touch on him made her move faster and faster, groaning into her ear as he chased the opportunity to fill her with his seed again.
Soon that opportunity literally came. Ty clenched tightly around Eileen's cock as she moaned in ecstacy, and he pumped his warm thick semen inside her. His seed would soon be surging deep into her body's depths for eggs to fertilize, and would make her pregnant.
