Eileen deepened the kiss and pushed Ty back down, his hulking masculine frame pressing atop her soft feminine one. She drank in the contrast between how his body and her body had changed- his intense male scent pervaded her sense of smell; his large firm hands gripped her own petite ones; his hairy chest brushed against her smooth perky breasts; and most intense of all, his throbbing erection rubbed at the supple flesh of her stomach.
Ty felt any concerns in her mind vanishing in response to Eileen's passionate yet tender touch. She realised the step she and Eileen could take to enjoy their new sexes to the fullest, and felt eager to take it, not caring about the possible consequences.
Once Eileen broke off the kiss, Ty breathed, "Eileen... do you want to fuck me?"
The handsome Brazilian man smiled and replied, "I'd like to go further, Ty." He leaned down and whispered sultrily into her ear, "I want to breed you."
Ty gasped, and once Eileen could see her face, she nodded. Her heart raced as she saw the man position himself above her, the firm penis that would fill her standing imposingly before her eyes, and then she whimpered as the tip of his cock slid over her clit and moist vaginal lips.
Eileen groaned and Ty yelped as he pushed inside her, his manhood spreading her slit open, and she gripped his wrists tightly. Inch by inch his shaft filled her, and she clung to him tightly with both her hands and her legs, loudly panting. To put her at ease, Eileen kissed at her forehead and moved his hands to her chest, rubbing and stroking at her nipples. To Ty's relief, discomfort soon gave way to pleasure.
After he had stayed almost stationary inside her for several seconds, Eileen whispered, "Is it OK if I move?"
"Y-yeah," Ty breathed, and as soon as she spoke she felt Eileen's hips slowly draw back and then thrust into her, his balls slapping at her crotch and the force and firmness making her moan. The DILF rhythmically pounded in and out of her, and her body shook with pleasure at his pounding motion.
At one point Eileen buried his head in Ty's shoulder, and Ty got an intoxicating view of his large dark body atop her, his thighs thrusting as he filled and withdrew from her over and over. What stood out to her was how right all this felt- even though she had used her wishes to transform this woman into a man and himself from a boy to a girl, their changed sexes gave them so much pleasure. Eileen's words about breeding her were echoing through her head- it aroused her so much to imagine his warm cum inside her, filling her up, getting her pregnant with his child.
She heard Eileen grunt with pleasure and then breathe, "Ty, I'm gonna- I'm gonna-!" She felt his balls twitch against her and thick cum shoot from his pulsing head, and the sensations made her hit her own peak. She moaned uncontrollably and her pussy clenched around Eileen, milking as much seed from him as she could muster, and her nipples and clitoris pulsed in sync with his ejaculations, both of them getting almost mind-numbing pleasure.
The two of them kissed sloppily but eagerly, amazed by the sensations of their inversed sexes.
