As the mass of semen inside Ty's stomach slowly subsided a little, Eileen asked her, "Can you birth another brood for me?" Ty could barely speak, and just nodded in reply. Eileen kissed her forehead, held her hand and smiled, "Good girl." Hearing those words made Ty's mind feel submissive to him: I'm his good girl, she thought, and I'll bear as many of his offspring as he wants.
With that, Ty's body swelled with pregnancy. Her stomach swelled to absurd proportions, soon getting too large and round for her even to stand with all the gestating offspring inside her. Her breasts also expanded, swelling to an absurd cup size with the nipples widening and thickening, giving her teats that would be perfect for her many young to suckle on.
Her children would not be the first to feed from her, though- Eileen noticed her swelling breasts and put his mouth to one, licking along the nipple and then sucking at it, making Ty moan in surprise and lactate. Eileen swallowed every drop of milk Ty gave him, and then looked up at her with an aroused smirk. "You've got bigger boobs than I ever had now," he told her. Ty blushed and felt her heart race faster as Eileen kissed her, his manhood rubbing along her huge pregnant belly as if teasing her.
Ty whimpered as she felt her water break, and to her relief Eileen returned to between her legs, spreading them and setting about to help deliver their next offspring. Her lips were surprisingly comfortable with distending to allow her to birth the litter, and again she couldn't even try to count how many fruits her body bore, just lying practically losing her mind while her lover dutifully severed each child from her and passed it to her breasts to suckle.
Once the last child emerged from her and had been nursed to sleep, Eileen hugged Ty close and the two wondered what to do next...
