last year we bought a large pool for the garden mainly for the kids to play in during the hot weather. My mate came round who is 47 lived with his mum all his life, weighs about 6 stone is really skinny and has a bad stutter, we were having a BBQ party and as the night wore on and the kids had gone home or to bed the adults decided to play in the pool. most of us stripped to our underwear and splashed about men in boxer shorts the ladies in bra and pants, my mate took his jeans off and he had a pair of high leg tight Y fronts and his bulge was plain to see for everyone, i noticed one or two ladies kept glancing over to it. and when he slipped over and landed on his backside in the water they were almost transparent,he became a bit embaressed and sat on a chair by the patio trying to cover up with his hands, I offered to loan him a pair of my shorts so he could continue with the fun. He agreed and I was about to take him up to our room when my wife said she would show him the way as she had to use the bathroom anyway. after about 5 maybe 10 min I hadent seen the bathroom light go on. so I slipped away into the house and upstairs. they were our bed room Bob was sat on our bed and my wife was knelt infront of him sucking his cock that was about 9 inches long and very thick. I watched from the landing for a short while until she stood up pulled her wet panties to one side ans sat on his cock and started to bounce up and down ( something she rarely dos with me saying she has a bad back) I walked in
