My wife has huge, firm 34DD breasts that have grown even bigger since she's gained a few pounds so her bra's can barely contain them. She is a short MILFy type, not fat, not skinny, but her boobs looks even larger because of her height. They look amazing, but she dresses mostly conservative.

Her sister is also well built, but much taller. I found out later she is a 34DD with large jiggly tits because she does not work out as much as my wife. I have only seen her a time or two without a bra because she is so jiggly it's very clear she is not wearing one. Which looked amazing.

My niece is about 5-7, cute blond in her early 20's. She is a spitfire and always has to be in the middle of everything. I rarely gave her a second thought because at family gatherings she'd bug the hell out of my kids so she was always causing me problems. As she got older and more mature, she's turned into a nice young lady. She dresses like a normal 20 something, tight fitted clothes, but I never gave it a second thought.

They were coming up to stay with us for a family vacation and we plaaned to go to the lake a rent a houseboat. I wasn't real thrilled about it, but it was better than working, and would be nice to be out on the lake.

The day before my wife said the girls were going shopping. She said she was going to look for some new bras because hers had gotten too small. Then out of nowhere she said, did you know my sister wears the same bra size as me? Obviously I am human and always love to hear boob information but didnt want to let on like it was a big deal, so I just said huh, who would have known. Obviously her sister's height made her large boob size less noticeable.

Then she said, out of nowhere, "and Megan (the niece) is the same bra size as me!!!" Well that caught my attention and I never would have guessed that either. They went shopping and of course all their clothes were stored at my house, so naturally I had to check it out for myself, and sure enough my SIL and niece both wore 34DD's like my wife.

The next day we all went out on the boat. My wife and SIL were in pretty conservative swimsuits because their mom was with us (who also has huge tits). My niece had on a suit with a t shirt over it. Once we got parked, she stripped it off to reveal a huge set of DD tits that stood straight out firm in a very low cut bikini. I'm sure my MIL about passed out when she took off her t shirt. Her huge tits had just a bit of jiggle to them, just enough to let you know they were huge, and they were real.

So here we are boat anchored in the water and she was walking around back and forth right next to me and had these perfect huge tits. Fortunately I had on sunglasses because I couldn't take my eyes off of them. So yes I am going blame my wife for sparking my interest by giving me TMI about my niece's tits, lol.

Later that night when they showered they do not have any idea that our spare bathroom that was remodeled has a small slit where someone can look in and you can bet I happened to be walking by when my SIL and niece were showering.

As I thought my SIL had nice big, a bit saggy, boobs that jiggled with every step. I'd do her in a heartbeat, but from what my BIL has told me she has little interest in sex like her sister. But my niece, omg, a perfect tight 20 something smooth body. Shaved pussy, and her tits were just as I imagined them to be while staring at her bikini. Perfectly shaped, point out straight ahead, large firm boobs, with perfect quarter sized areola and erasure sized nipples.

I'm hoping we go back to the lake soon... lol
