This is a true story.
Back in 1974 my brother Bob and I got into the habit of masturbating several times a day in our room. Not unusual I know.
Yes, as you expect, we were eventually caught by our mother. We were lying on our parents' bed going at it like mad monkeys looking at some of what we thought was our father's porn. Our mother walked in, saw what we were doing and reached for our magazines. She quickly flicked through them, shrugged her shoulders, told us to finish what were doing and get in the shower and dressed before our father got home.
I thought we were in for some trouble, but my brother seemed to think of it as a turn on. Mother had caught us and told us to continue, that's all he could think of.
Later that night after dad came home, our parents took us to the Pizza Hut where they launched, in albeit subdued voices, the subject of my brother's and my masturbation. The first thing my parents made clear was that masturbation is normal. They said everyone does it and those that say they do not do it are lying.
Our parents masturbated too? As Bob and I got over this new shock, we listened as our parents told how they had maturbated since their early teens and when we are not around, continued to masturbate around the home whenever and wherever they liked.
Nudity being not only accepted within our home, but being the common theme, I couldn't help but imagine my father and mother having a quick reach for it whenever we left the room.
Needless to say that our shock soon gave over to wanton horny info seeking. The more we talked, the more relaxed we became. Eventually Bob and I realised that within the family, solo touching was as accepted as general nudity. It was a fact of life and we soon adjusted.
Some weeks after this, Bob and I walked in on our parents. Our father was lying back on the recliner while our mother was riding a black rubber dildo while maturbating our father.
Although by that stage we'd seen both our parents masturbate with and without objects on numerous occasions, this was the first time we had seen them doing anything other than kissing.
To cut a long story short; no incest occured. Our parents expanded their sexual practices from totally private to wherever and whenever. If Bob and/or I were around when our parents got in the mood, we were welcome to have a solo touch while we watched.
And some of the kinky things we watched, I wouldn't dare mention here.
