I just found this confession site. I admit, I've already masturbated quite a few times while reading some of these! Thanks!
Anyway, my confession could fit into a few different categories, but I picked this one because it's always been a fetish of mine.
I'll jump right in: Last summer I was helping my parents remodel the upstairs of their house. It was hotter than hell up there every day I worked. With the upstairs demolished, that left only one bathroom downstairs. I would usually take a quick shower before heading out to my own place. Not a big deal.
So, my mom has always been the flirty type. She's a real cougar.
One day it was just mom and I working upstairs. Dad was at work. I had finished hanging drywall and we started painting. I had been there all day and after we decided to stop, we both suddenly said "I need a shower." We laughed, but the out of nowhere my mom said "let's go then."
I didn't think she was serious but I thought I'd calm her bluff just to see how far she's take it. We went downstairs and I had my shirt off by the time we went into the bathroom. Mom was trying to act cool and calm. She laid out some towels and started the water. I had my shoes and sock off and was unbuckling my belt when she stopped fiddling around. She froze when she saw I was actually going to strip. I thought for sure she would walk out then, probably call me a choice name or two, but she didn't. She smiled and in one quick, well practiced movement, she pulled her dirty T-shirt over her head.
I'd seen my mom in her bra before, no big deal. She did have a nice set of boobs, though. I undid my fly and started to unzip. Again, I thought this would end before too much longer, but as I slowly slid off my jeans, my mom undid her bra and threw it at me. I looked up to see those big tits. I just stared as she shedded the rest, pants, panties and stepped under the water. My mom was naked. I snapped out of my daze when she blurted "are you just going to watch me?"
I shook my head and said no. At that point I was just in my underwear and it was impossible to hide my excitement. I thought what the hell, and chucked off my undies. My swollen cock bobbed up and down and I stepped into the shower.
At first we didn't touch, though the space was limited. The we decided to help each other. Washed each other's back and she turned and allowed me to wash her breasts. My cock rubbed against her belly the whole time.
We barely talked, just enjoyed the water and each other's bodies, as I washed her tits her hand slid down my side and quickly touched me cock. I said it was ok and without further hesitation she wrapped her fingers around my swollen shaft for a few tugs.
Laughing, I held up the soap and said "it's not going to get clean without this." She took the soap and lathered my cock and balls up. While she washed me, I slowly slid my hand down her stomach gently to her slit. She gasped a bit as a finger probed her and she tugged my cock harder.
We played with each other for quite a while. I finally whispered that I was going to cum and my knees nearly buckled with each pulse.
We both nervously laughed as things tamed down a bit. We washed each other again, really actually washed.
After getting dressed we both were apologizing a lot. My mom even cried and I assured her it was ok. We both just got carried away and we swore to each other it wouldn't happen again.
The remodel was finished a few weeks later. Life has continued as normal for the most part. I masturbate quite a lot thinking or her. I'm thinking of asking if she wants to try out the new master bathroom when I visit the next time. As long as dad isn't home, that is.
