Within a month of my induced lactation, I had settled into my new role as Jack's milk cow. My milking schedule was now at 15 minutes per breast every four hours, and I was producing a lavish amount of milk. We used a dual pump, so the time involved to empty both my breasts with the milking machine was more like 40 minutes, but if Jack milked me orally (which we both preferred) it took 45-50 minutes. This pleased Jack enormously, especially since my breasts had grown even more with the milking regimen. Six months into our program, my bra size was 42DDD, and my long, dark, thick nipples seemed to remain hard, awaiting Jack's mouth. Every milking session ended in a delicious orgasm; even if Jack wasn't around, the toys I'd accumulated did the trick.
One night, Jack came home, smiling slyly. I met him at the door; he was a bit late, and my breasts were more than ready for milking. The long blue silk gown I wore showed off my very heavy tits and my plump belly and ass, just the way Jack had molded my body through regular feeding and milking. My nipples were prominent through the thin fabric, and I knew if my milking was delayed much longer, I'd begin to leak, especially as Jack's mere presence turned me on. It was practically a Pavlovian response: Jack walks in the door, my nipples harden and my pussy gets wet.
"What took you so long?" I pouted, beginning to stroke Jack's ass through his jeans as I followed him into the living room.
"I was talking to my sister. She and Steve are still trying to conceive, and the IVF hasn't worked. They've spent a fortune on medical procedures, and they're thinking of looking for a surrogate." Jack turned around, putting his arms around me and fondling my ass, pulling me against him and kissed me. "I know we've talked about having kids, but what do you think about a trial run?"
Jack and I had discussed having children; we were both eager for me to be pregnant and continue to grow my body, but we were concerned about the crimp that children would put in our sex life. We figured that three or four years from now would be plenty of time to reproduce. I looked up at him. I liked Jack's sister Diane, though I knew she was perplexed about my relationship with Jack; she couldn't imagine why I had gained 35 pounds since I'd known her brother, and furthermore why Jack seemed to enjoy it. She certainly didn't know about our milk cow games. "Wow," I said. "What do you think she'd say if we offered?"
"She hinted that she'd love to have someone close to her carry the baby," Jack murmured, kissing my neck. "I didn't want to say anything until I talked to you, but I think she and Steve would be thrilled."
"Let's talk about it tonight over dinner," I smiled, kissing him. "Right your little heifer needs some attention before she starts to leak." I pressed my full, aching tits against Jack's chest, loving the feeling of my long, hard nipples rubbing against the rough fabric of his shirt. Jack cupped my breasts in his hands, feeling how heavy they were, and stroking my nipples through the silk of my gown. At his touch, I arched my back a bit, pressing my belly against him and giving him better access to my milk-swollen tits. Sliding one thin silken strap down my shoulder, Jack lowered his mouth to my nipple, licking and nuzzling it.
"This may be a wonderful opportunity," he murmured.
"Oh, yes, please" I answered.
