Caught Best Friend Jerking Off

We ended up there on a Friday afternoon and jumped in the pool immediately. We swam and fished for hours until it got dark. My grandma came out and told us they were going to bed and so we needed to keep it down. A month or so before that, me and my best friend found my grandparents' liquor cabinet and started doing shots of liquor for fun. Once they said they were going to bed, we decided to dry off and head in and once they fell asleep, start having drinks. I knew being in the pool all day. I had sunscreen all over me. So I told my best friend. I was gonna hop in the shower and for him to make us our first shot.

I didn't think I was in the shower that long. I walked out and didn't see him in the kitchen where the liquor was. With my grandparents being asleep, I quietly walk the house looking for where he is. I know there have been a bunch of times that he and I grabbed my grandfather's Playboys and enjoyed looking at them and jerking off, I thought maybe he was doing that. I turned the corner and to my surprise, I saw my best friend standing in front of my grandparents' bedroom door butt naked jerking his hard cock. It's not like over the past 3 years. I haven't seen it so that didn't shock me.I just didn't understand what he was doing. I stood there quietly intrigued at what he was doing. If I had to guess, it only took about ten minutes and he was shooting loads of cum onto the floor where his swim trunks were laying. Once he finished and bent over to grab his swim trunks. I went around into the living room as if I wasn't there.

A couple of minutes later, he walks past you with his towel on and says he's going to take a shower. He felt like he had sunscreen on also. I didn't mention anything to him at that point I just said okay. Once I heard the bathroom door shut, I slowly walked over to my grandparents' bedroom. That's when I realized what he was doing. My grandma at this point in life was a full-blown alcoholic, and she was definitely drunk when she went to bed. She fell asleep naked in bed, and her legs were spread wide. From the doorway of her bedroom, you could see her larger breasts and her hairy pussy. Being a fifteen-year-old boy, I guess it didn't really matter who was naked. Standing there knowing that my best friend had just jerked off to this and seeing her naked I could feel my own cock starting to get aroused. I hurried back into the living room to see if I could hear the shower on and it wasn't on yet.

I ran back to the bedroom door where my grandma was laying and grabbed one of the towels from the kitchen. I dropped my shorts and put the towel underneath me and started stroking my cock. For an older lady, she had really nice perky breasts and her nipples looked to be hard. Her pussy had a hairy gray patch and with her legs spread.You could see the lips of her vagina. It didn't take me long and I could feel it myself ready to cum.  I exploded multiple loads of cum onto the towel and floor. Once I finished my orgasm, I used a towel to wipe up the come that missed the towel. Just as I did that I turned and my best friend is in the kitchen, making a shot.

I walk into the kitchen and he says to me oh I see you noticed grandma is naked as well. I laugh and said yeah. I saw you already shot a load. He just laughed and said. Yeah, I couldn't believe she was laying there naked. It's not even like I find her attractive, but a nude women is worth the load. I agreed and we both laughed.  Somehow weekends at my grandma's house with my best friend seemed to always have alcohol, porn, nude girls and a bunch of jerking.
