Ty felt June sit up and pull out of her, seeing his phallus was now covered in their combined juices and feeling his semen start to leak from her pussy lips. She felt acutely aware of, and weirdly aroused by, the fact that she would be bearing this man's child.
Correctly guessing this, June grinned at her and teasingly said, "I wonder how many times you milked cum from your cock imagining getting to do this to a girl?" He leaned in and purred, "Now you never will. Instead, my seed will make you carry my offspring."
Ty felt kinda surprised at how right that felt to her. June was more of a man than he had been, let alone than she was now, and having his manhood give way to womanhood for June's sake had felt so fucking good.
His hand stroked the supple flesh of Ty's stomach, and she shivered in anticipation. "In fact, I think you should use your powers to birth my child now." June's tone told Ty this was a demand and not a suggestion, and she felt intrigued by the idea too, so she wished for it.
An indescribable sensation ran through Ty's body as the development of the embryo gestating inside her dramatically hastened. Her stomach began to expand little by little, and in her mind's eye she saw the child developing inside her. "Good girl," June smirked. "You'll be a mother soon."
Ty nodded, and her belly continued to grow softer and rounder, her breasts also swelling as they prepared to produce milk for her child. Eileen cupped Ty's swelling bump and teasingly asked, "I bet you feel claimed by my seed, don't you?"
Ty hadn't considered this, but now he'd said it she realized it felt just like that- and it turned her on a lot. She'd been fucked by this man and her body and life would have a permanent signifier of it- the result of his seed conquering her body's depths. When she felt it move and kick inside her, it reminded her of having to share her body with June's progeny.
After a few minutes, her water broke and she realized she'd be birthing his child. To her relief, June moved down to her crotch, cleaning his seed up so he could comfortably deliver their baby, and it emerged with surprisingly little pain on Ty's part.
Ty nursed the baby as it suckled at her breast, and wondered whether it was a boy or a girl...
