My wife Liz and I have been married over 20 years and she is a sexy blonde who is 5'3, d cup boobs, and a trimmed sexy bush. At the time this happened she was 40 and her brothers were 43 and 46. We were going to a nascar race in Michigan with the three of us and another friend Scott. Her oldest brother Jack is married to a pudgy girl who is not hot at all. Her brother Danny is the middle kid and she is the baby. I love showing Liz off to my friends and anyone else who i can let see on the downlow. She is freckled on her chest and shoulders and I think she is super hot. Anyway, we are in an RV going to the race on a Saturday morning having a few beers (except Scott who was driving). Once we got there we parked in the grass lot where we rented space and set up camp. I hatched a plan the week before we left to show both her brothers nudes of her and super exposed/spread etc. We were sitting around drinking just after dinner when i sent myself a text with ten of her nudes and made my phone ding. I looked long and hard at the phone saying "damn he's a lucky bastard" and So hot. They all asked what i was looking at so I told them my buddy from work sent me pictures of his new girlfriend who was in her early 40s. I made sure in advance to keep all head and face cropped in the photos and the backgrounds generic like hotels we stayed etc. I handed the phone to Danny and he was entranced. He scrolled through the pictures of his sister and was saying he'd fuck the shit out of her. I was so turned on knowing that she would be mortified and he would probably be too if they knew. I know it was kind of wrong of me but i was so horny and they were just pictures..lol..thats how i justify my kinks. He handed the phone to Scott whol enjoyed them and then on to Jack who oohed and aahed over them making comments about how her nipples were so hard and how wet she was. I wanted to go jerk off asap in the RV i was soo horny. Danny asked me if i could send them to him so he could "use" them later. The thought of him unknowingly jerking off to his little sister was too good to say no so i said sure and sent him all 10. Later when we went to bed i could hear him grunting and see she arm pumping. his cock on the pull out bed near the front of the RV. I only lasted about 2 minutes as i pumped my own cock to a very full load that had been brewing all day.
Let me know if you want to hear about the next day......
