One Saturday morning I was going into the side door of our garage to grab my bike, the door was slightly ajar so I guessed that Mom left it that way when she left for her girls day outing. I pushed the door open and walked in. Most of the garage was in darkness except what my Dad called his mancave over on the far side. He had it secluded with shelves full of tools and books and stuff but I could see a light. I wondered if he was tinkering on a project while Mom was gone. For some reason I was quiet, and I heard an odd noise like a moan. I stopped and listened and then I heard Dad’s voice calling my Mom, Lois by name. I knew she was gone so I thought he was on the phone, but I heard another moan, then what sounded like my name, Beverly, but I knew he always called me Bev, so I wondered what was going on. 

I moved closer to the shelves and through a partially empty spot I saw my Dad, totally naked. He had two pairs of panties, one he was sniffing that I thought were mine and a thong of Mom’s and it was wrapped around his thing, his penis. I was mesmerized and stood quietly watching. I realized he was masturbating with our panties. That was surprising for sure. What was wild was him moaning out our names like he wanted us to be there. Then all of a sudden he arched his back and called my name again as his penis shot white stuff from it. I let a gasp escape my mouth I was amazed. He heard me and was so startled. He for sure called my name then. I was trembling thinking I was in deep trouble. 

I moved so he could see me around the end of the shelves. He blushed slightly and so did I. My Dad was there with panties in both hands, his bare penis pointing upward, leaking drops of the white stuff still. He told me he was sorry that I saw him like this. I asked if he was ok. He realized quickly I had no idea what I had just seen was all about. He took a towel and wiped his cock and told me to not be frightened. I asked if I was in trouble while I stared at his body. He smiled and said no of course not. He was just having a moment to relax and relieve some stress. He moved to me and asked if I had watched long. I just shook my head. He asked if I saw what happened and I nodded. He explained it was called an orgasm. That he was masturbating. 

 My eyes were wide open looking at his penis so close now. I had talked with girlfriends about masturbation but had not tried it. We knew about boys having a penis and that it should go in a girl’s vagina or pussy. But that was the extent of my knowledge. Dad let me know I was in no trouble for walking in on him. My lower lip was trembling as I kept staring at his penis and then our panties. He said he uses our panties because they are soft and smell so erotic. I noticed he had gotten soft but now was starting to get hard again. He took his penis in hand and told me I could watch this time. He moved back to his stool and put some stuff on his shaft. He told me it was lubricant for his cock. 

I blushed at hearing my Dad’s language change. He started stoking again but not using our panties. This time he was telling how much it turned him on to be watched. That Mom loved watching him masturbate and he sometimes watched her too. His fist was wrapped around his shaft and the head turned a deep purplish color he was gripping it so tightly. I licked my lips as I watched. He must have realized I was enjoying getting to watch. He told me he wanted to cum for me, to cum this time with me right there to see his cum. I was so amazed. Suddenly I felt so grown up. I got wide-eyed as he soon let loose more cum, spewing like a volcano. He promised me if I kept quiet about our secret he would let me watch again. I wasn’t even to mention to Mom, at least not yet he said, and I promised. I hope this is a good start for you.
