He Goes Back And Continues

Hearing his Aunt's plea for help John turns and walks back in. The sight of his Aunt with beachball like breasts each leaking warm milk was too much to leave behind.

"Don't worry Aunt Jessica I'll help you out." He smiles as he walks behind her and starts to feel up her swelling bosom.

"H...how is this helping?!" She shouts as she's manhandled by her nephew.

"I'm helping you become what you should be. A big cow! Perfect for breeding!" He says with a devilish grin before pulling down her panties and shoving his hard cock deep inside of her.

"N..no! Stop it! I'm your Aunt!" She screams as John picks up the pace. Her breasts are so big and full with milk that she's struggling to stand. Soon enough she's on her knees, too busty to get up.

"Just a little more..." He groans before releasing his warm load deep inside his precious cow of an Aunt. "There we go! You can name the kids after me" He smirks before walking upstairs.

"Wh..what do you mean?!" Her voice is trembling. Suddenly her body begins to bloat around the middle. "John! John! Don't leave me! What's happening to me!" She screams as her womb balloons with his children, more and more embryos taking root inside her as they begin to grow and develop getting bigger with each second. Within ten minutes she was looking close to full term with twins but she was only getting bigger.
