Got Caught And Later Taught

My aunt and cousins lived fairly close to us as a kid. It was a 20-25 minute bike ride. My cousins, one boy - year older, two girls (one the same age as me and a year younger). The girls were, and still are super sexy. Oh and my aunt was amazing. She was dark haired, Irish-German with a touch of Japanese.... They had a pool. My cousin, Jim and I did all of the normal summer things, fish and camp and shoot by guns.....and always finished the hot day in the pool. As we aged we discovered some dirty magazines (was the 70's) and together we had Jack Off times up stairs in his room or out at our lodge in the woods. Once, at 15, I rode my bike over there for normal activities but Jim was gone for the day...had to go help his grandma with some chores, got called as I was on my way.....era before smart phones..... So I arrived and he was gone. I went to our lodge, got fishing gear and fished....then went back to house and my aunts car was not there but I heard music and giggling from the pool so I walked to the fence quietly, I peeked over (luckily I am tall, then I was 6' now 6'8). And saw cousins in changing room. So I snuck around to side with vent and small circular window....they were naked and dancing to song on radio....I promptly pulled my dick out and started stroking.....and being a teen. I was close quickly, .... I suddenly hear a gasp and then my name......... My aunt was home, her. Car was at the shop for tires or??? There I was with cutoff jeans at my ankles, my cock hard and dripping precum........ She listened at window (not tall enough to see) and then she dragged me to the gate and into pool area and the change room. She told the girls to cover up and dragged me straight in....still semi hard...pants still tripping me. She then berated me as the girls looked at me and my shame (later my joy-as I love CFNM situations) ...."He was playing with himself, peeking in at you girls. Now he will play with himself in front of you girls." So after a little hesitation and a slap on the ass and on the head of my now hard again dick, my Aunt left the room and I started jacking off for them...not knowing any better I finished quickly and shot a huge teenage load all over the red "AstroTurf" carpet. She came back in when I had finished and said this will be just ours, no need to tell anyone girls.... Little did I know what fun this would portend at that house in years to come, with that aunt (have done it with her for at least 34 years until she passed from cancer....Even gave her a gift in hospital, when she requested a show when she was sick.....
