One summer break during high school, I had access to cable porn and spent most of my late night/early mornings jerking off until I couldn't cum any more. One day, I had locked my door as usual in case my parents decided to barge in, stripped naked and turned off the light and found a good bit of porn. As I was getting myself going, my female dog woke up from the corner of my room. I hadn't noticed she was there. Instead of letting her out, I thought what the fuck and proceeded to stroke my cock. She was watching me intently and started inching closer. I was so focused on the porn I didn't realize she's was up on me until I felt her tongue brush against my thigh. I got up and pushed her away, but in the process, she nudged under my balls and gave me a good lick underneath. It felt so good, I spread my legs for her to get a better angle. She slowly licked my balls and my asshole as I stroked my cock. The people in the porn were going at it doggy style, so I decided that's what I wanted. I got behind my girl, spit on my finger and started sliding into her. She was so hot inside, I almost came right there. I pushed my finger on deeper and she pushed back against me. I was so turned on, I pulled my finger out, spit on my cock and slid it in her. It was amazing. The velvety tight feeling, the heat, her body pressing against mine. It only took a few minutes before I was emptying my load into her puppy pussy. I pulled out and my cum gushed from her. She turned around and started cleaning herself then came over and licked me clean. It was the best feeling ever, and we fucked often.
