My sixty-ninth (nice) caption. this time with a Christmas-themed version of the TransforLife App.

You and your girlfriend Mary decided to be kinky for Christmas, swapping bodies using TransforLife. Unfortunately, what she didn't tell you that she'd be offloading some of your… excess weight in the process, leaving you with a heavy burden to deal with in her own body.

TransforLife was easily the biggest phone app that had ever existed. Using advanced technology that seemed like something out of science fiction, the app was capable of changing aspects of the user or a third party in incredible ways. While originally built as a machine intended to provide transgender patients with the body of their dreams, the app version had spread like wildfire, allowing people to modify their bodies and lifestyles to their liking. Still, even with the limits, safeguards, and usage tracking built into the app, there were those out there who had learned to jailbreak the app’s functions, allowing them to transform themselves and others into just about anything imaginable. Whether through accidents or malicious use, many people disappeared, never to be seen again…

“OK, well I know I agreed to the more… kinky stuff, this is really starting to get a bit out of hand, Mary.” I complained, hefting the two enlarged boulders she called breasts. “Was this really needed? I can already feel the pain in my… your back forming as we speak.”

“I certainly wasn’t going to lug around all that pudge under your shirt the whole time. Besides, you still owe me for leaving me transformed as a onahole for that weekend, remember?” She shot back in my body, looking quite snug. “You look good anyways.”

My girlfriend Mary and I had used the TransforLife app to swap bodies for the Christmas weekend, trying to find new ways to spice things up for the holidays. We weren’t going to any parties or restaurants for the occasion, so we decided to bunker down and try out some holiday-themed lingerie we had bought for each other instead. The problem was that Mary had secretly changed some of the parameters we had agreed on, mainly transferring some of my body fat over to her body during the swap, leaving me heavily encumbered while she got a thinner, more agile version of my body. I had to admit, I was somewhat upset by this little change.

Later that night after dinner, we made our way to the bedroom to slip into our respective outfits. The lacy, thin Mrs. Clause outfit I had bought looked comedically tiny with my new proportions, and Mary had quite a laugh at this, seeing the straps to the bra dig into my undefinable boobs while she got to wear the most modest, but still sexy, male equivalent. This was unlike anything else I had felt.

“I’m surprised that little thin thing has lasted this long.” She joked, pulling up on it slightly and letting go, getting my heaving bosom to jiggle like the two globs of flesh they were. “And to think you wanted me to do this instead… serves you right, you big damn pervert.”

“Look, I admit my mistake and was wrong, but this seriously is too much.” I argued, holding my breasts up with my hands so I’d have some semblance of support. “Isn’t there any way we can… even things out? Some way for me to make things up to you, babe?”

“Nope, I like you the way you are.” She denied with a smile, getting me to pout. “Come to bed, honey. It’s getting cold with the snow.”

I grumbled to myself, rolling into bed as best I could as I let my breasts fall to the side. Just as I was about to pull the covers over us, Mary suddenly pulled out two suction cups attached to a pump out from under the bed. Before I could question what was happening, she switched the machine on and pushed the cups into my two enlarged nipples, sending a sudden wave of pleasure through me as milk shot out of them. My mind went foggy as she smirked, putting one of her arms around me and giving my neck a nice long lick.

“This is my present to you, honey. I’ve read online that if you convert body fat to milk with the app, you can suck it out with a pump and it won’t be reverted once you change back.” She explained, massaging my breasts as I began to moan out in pleasure. “I decided to increase your sensitivity as well, so for the next few days, you get to be my good little Christmas cow, and you lose weight too.”

“T-Than-k y-y-you…” I stuttered as best I could as she leaned in for a kiss, going so far as to stick her tongue in my mouth too. For the next few hours that night, we had sex much like we often did, but the pumps stayed on the whole time, producing a surprising quantity of breast milk. I got so into this new roleplay that I actually began to moo like a cow too, thoughts too cloudy to form words.

By the end of the 25th, Christmas Day, my breasts had shrunk significantly, finally allowing me to fit into her clothes properly. The three-day timer was just about up at this point, but as I looked at the collected milk, even more perverse thoughts entered my head.

“Hey Mary, what would happen if I… drank this milk?” I asked with an incredulous look, biting my lip as I imagined how I felt before.

“It would go right back to my breasts, wh-” She began to say before noticing the red, perverse expression on my face. “Oh… so you liked it that much, did you? Well, I suppose we could keep this going to New Years if you wanna be my little cow a bit longer…”
