Just remebered this happening, still get embarrassed just remembering.
Grew up in a small three bedroom house, two baths. One bath shared by two older sisters and myself. Sisters shared back bedroom, my bedroom directly across hall from parents.
After older sisters married, back bedroom became mine, telephone and all. whee hee.
At this time computers were just experimental, no dvds, not much adult material to look at except adult magazines.
The bottom drawer in closet had my collection of all sorts of completely nude and semi nude ladies. Many times I held a magazine in one hand and jacked off while looking at a sexy looking naked lady.
One morning I was looking through probably around ten or twelve magazines, teasing, jacking off and dreaming all these naked women were watching me.
Placing pillows and other stuff under magazines, I was surrounded by nude ladies. Stroking, slowly looking at each open page with open legs, sexy rear views, great looking breast, Stroking, looking, stroking. Oh yea, getting close.
Knowing door was locked, didn't have a care in the world. Was looking at all them nude ladies and jacking off like the world order depended on my getting off!
One lady had one breast smaller than the other, one had wonderful dark trimmed hair etc. Oh yea, building up enough pressure to launch the space shuttle.
Don't know how long door had been open but, there stood Mom and both older sisters! All three were bunched up together looking into room!
Could not stop hand in mid stroke, up and down, up and down, closed eyes!
Oh spit, what the? Still holding shrinking startled manhood, a few more little strokes, opened eyes. All three were still bunched up watching.
Seeing no one was talking, women just looking, no I'm thinking staring, had to say something.
(What do ya'll want)? After more staring one of them said, (lunch is ready).
Walking to kitchen table noticed, both bro in laws grinning, ate meal with family and split!
