SIL #1

So my SIL is a fairly plain looking 40 something but has always had a killer body. I never paid much attention to her until we were at a family function one time and she had on one of those half shirts like we would wear in football that exposes your stomach, so for her it ended right below her nice sized tits. Seeing as how the women in the family are very conservative it was quite the scene. She was younger and slimmer then, her boobs were large but not like now.

Fast forward 20 years up to a couple of years ago. I hadn't seen her in quite some time and when I did I was shocked. She had put on some weight but didn't look like a typical BBW, more like an amazon. She was never fat but solid, just a big solid girl, but her boobs had become enormous, like most of her weight gain had gone directly there. To look at her you could not ignore that she was all boob now.

The first time that was odd was family pictures, she would always end up beside me and I noticed more and more she would slide up next to me and press her tits against my arm. Or if we were in line getting food. The first time I blew it off thinking it was just an accident but it happened the next 2 or 3 family occasions, which I thought was strange.

She can be something of a pain in the ass, there were times I wondered why my BIL stayed with her, but I'm sure that tremendous body had a lot to do with it. For some reason she's always treated me different because she knows I won't take any shit off of her so I think she respects that, you can tell when someone acts different towards you than everyone else close by.

She gives off mixed messages about her boobs, saying "I'm going to get a reduction, then in the next breath bragging about how some random guy was gawking at her and even told her how great her boobs were to her face. I'm sure they are a pain, literally, to carry around but they get her a lot of attention and she gives off messages that she enjoys it.

She usually tries to cover her big melons up for the most part, wearing oversized sweat shirts and such, but this was summertime and near 100 degrees and we were working outside, so she had no place to hide them and had on a thin white t shirt. There were several of us working on a family project and she and I eventually ended up alone taking something apart. I was totally focused on the project and she was handing me tools, not looking I reached over for some pliers she was holding and got a handful of enormous boob. I quickly let go and looked at her and muttered something about "oh sorry" and she just looked at me and smiled.

After that I got a little bolder, when we would do the family hugs, the first time was unintentional, but its like you have to go around her boobs to get your hands behind her to hug her, lol, so I grazed her boob and got no bad reaction. From then on, anytime I get the chance to hug her I try to brush or press up against them as long as I can. She's not an idiot, I'm sure she realizes it.

We live in Florida a couple of blocks from the beach, so we get the family visiting on a regular basis. One time when she was here they were out shopping and I looked at her bra and it did say 38FF which I understand is a G. I tried to find a boob model with similar features and the closest I could come up with was Tessa Fowler only bigger, which is suprising because Tessa is a GG and SIL is bigger than her. SIL could easily be a boob model if she wanted.

Since they visit a lot, and we have other people stay in our house through places like VRBO, we have security cameras pretty much everywhere, but we tell renters that. We've told family several times, but apparently one of the times SIL was staying there she forgot and she apparently likes to walk around nude, so yep I got a nice set of videos showing her massive tits and full black hairy pussy, I felt like I had won the powerball, lol.

The most surprising part of seeing her nude was her boobs are so huge and hang down to just above her belly button, but her nipples are way up high in the middle of her tits, I've never seen any others like it, they are just perfect. Of course they would move and jiggle with every step and flop around, she is a site to behold.

Do I think she would take things farther? Maybe. But she is the type that I would never trust to fool around with, she would probably blab it to my BIL or someone and wreck the family, so I'll have to be happy with my occasional grabs and brushes for the time being.

It's not a story as hot as some of the fiction people put on her, but the above is 100% true.

My other SIL's boobs aren't as big, she's just a 34E, but she's a trophy wife, a hot 5'10 blond. I've seen her on the security cameras too.

Family is fun sometimes...lol.
