Hot air shot out of the AC from our 2016 Honda CRV as we drove down the highway to my in-law's house for an unseasonably warm memorial day cookout. My in-laws had a country house about an our out of the city with a big property which had a beautiful large field for games and a secluded, wooded pool area. I can't say that I am ever "enthused" to go over to their place, but one thing that did make it palatable was that my wife's sister and her daughter were going to be there. I always got along with those two in ways that I never fully connected with her other siblings and their kids.
My wife, Kathy, was the love of my life and we recently got news that would change our world forever. Kathy and I were expecting a child, a secret that we planned on telling the family at the cookout. Kathy had this plan to get everyone inside where she would then give her parent's a picture of the ultrasound to break the news. We were in the second trimester and Kathy was starting to show. Her string bean body was beginning to take an even more womanly form, her breasts have started to enlarge and her once pink areolas have started to darken and grow. I have to admit, although I had always been extremely attracted to Kathy before, I found her pregnant body increasingly seductive. Something very primal had awakened in me and I found myself becoming addicted to massaging lotion onto her tender engorged breasts even when I knew it wasn't leading to any further sexual relief. That morning, while I was watching her try to squeeze into her old bathing suit before heading out, I found myself walking up behind her, reaching around and playing with her now thick dark nipples. Alas I digress as this isn't a story about my attraction to my wife, although she plays a large role later.
When we got to her parents, we were greeted by Sarah, her elder sister, just about 39 years old and still an absolute knockout. She wasn't your stereotypical "milf", she didn't have platinum blonde hair, nor did she have enormous tits that busted out of her top. She was short and thin with a smile that melts your heart and was petite enough to make her reasonable bust contrast in a way where it would take a wrench to tear you eyes away at times. She had an incredible sense of humor and was an incredible flirt.
When she came over she was in a one piece bathing suit with short khaki shorts on below her waist and greeted us each with a hug before helping us unload the car and bring the cooler over to the grill area.
"Hey Matt," Sarah said, grabbing my attention. " I wanted to let you know that Dan's not able to make it this year, but he did send along a little care package with him." Then she led me to the pool house fridge and pulled out few four packs of mixed beers. Dan, her husband, and I had a customary tradition of bringing each other some nice beers we have tried since the last time we met up.
"Well let him know that Although I was a bit bummed out, I still gladly accepted his peace offering and I am assuming that you are part of this gift as well?" I said with a wry smile.
"Oh easy their Daddy, you don't want to get two of my parent's kids pregnant do you?"
I was taken aback, "Wait, Kathy told you?" I said incredulously.
"Of course, we tell each other everything," Sarah gave me an up and down then bit her bottom lip. "I was so surprised to hear this, I thought your little thing wouldn't even be big enough to make it in!" With that she giggled and skipped away back to the pool, looking back just quick enough to give me a wink before heading out of site.
I knew I had nothing to worry about, I had watched enough porn and been in enough locker rooms to know that I was of average length and above average thickness. An with Kathy's petite frame, I knew my wife was very satisfied with my "little thing".
Once we got settled in, I cracked a beer and fired up the grill, as was my typical duty at family events. About mid-way through cooking, Sarah's daughter, Katie, came out of the pool and started chatting with me. Katie was short like her mother, but unlike her had a bit of thickness in her midsection, nothing bad more like some baby fat that never left. She also had a pair of massive, heaving breasts which her bikini top struggled to contain despite its attempt at being a modest top. Katie and I chatted a bit about college and her hopes to study abroad next semester. We hit a stand still in the conversation, so I looked out at the family by the pool. I saw my wife bending down to grab a piece of food that fell on the ground as her newly engorged breasts nearly spilled out of her top.
"Uncle Matt, you must really be liking Aunt Kathy being pregnant, huh?" She said, looking at me, "who knows, soon her tits might be the size of mine."
Katie gently squeezed her breast together to slightly frame them while gently twisting from side to side.
"Jesus, you know too? Does everyone here know?" I said, getting slightly annoyed.
"No, no, just me and my mom. We are close is all, we tell each other everything," she said, brining my mind at ease.
"In any case, I am not sure if Kathy's double in size that they will come close to yours. I bet they each way more than the baby will." I said, while flipping the burgers onto a tray.
"Well, too bad for you, you will never know although..." she paused, looking down at the outline of my stiffening member, "I bet you've thought of it a couple times," then she scampered off, just like her mother.
"Well today is far more interesting than I thought it would be," I thought to myself before shutting the grill off and announcing that food was ready.
After eating and chatting with the family, Sarah and Katie announced they were going to go in the hot tub. Kathy went to join them but stayed on the outside. I was in mid-conversation with my father-in-law when Sarah shouted over to me, "Matt, get your boney ass in here, you cooked all day now its time to relax!"
