After a family dinner I stayed over at my cousins. We were maybe 16 or 17 at the time. Most the family had been drinking so a bunch of people ended up staying the night. It was getting late and I was looking for a place to crash. My cousin let me sleep with her. In the middle of the night i get up to pee and grab a drink. The dog must have heard me and came upstairs to see what I was doing when I noticed he had a big boner. I laughed and watched for a second. I’ve never seen one in person at that point and curiosity took over as i gave it a good inspection. I went to grab it and he took off downstairs. When i followed him down he was standing at a closed door to the laundry room. I was just about to open the door when i heard some moaning on the other side. I could tell it was my aunt. I figured she was masturbating or something. The dog was making a fuss to get in and i didn’t want to get caught listening so I pretended to be asleep on the couch near by. When she let the dog in, the other dog came out of the room. He came up to me all excited as i was pretending to sleep and starts licking me in the face. I do a fake half asleep roll over to try and play it off, only to have him jump up and start humping me. My aunt calls him over and goes back into the room. I waited a bit and went to investigate only to find my aunt in plain view with the dog mounted on top of her. I couldn’t believe my eyes, the dog was just pounding her. She had to have wanted me to see. I watched for a min as the dog slowed and finished. I was extremely turned on. She caught me peeking shortly after and I ran back to the couch. I was pretending to be asleep again and my aunt came over and sat next to me. She leaned over and whispered in my ear asking if i was curious. I was too embarrassed and shy to answer. She whispered again ”it feels amazing.” as she lifts the blanket and starts to rub my back. I worked up the courage to say ”ok” and she starts rubbing my butt. Slowly making her way between my thighs I let out a little moan and she pulls down my booty shorts. I hear one of the dogs make his way over. I’m laying on my side and my aunt pulls me to the edge of the couch. Right away i feel the dog start licking me. His warm tongue reached every nook of my ass. After a few mins he tries to mount me and she stops him. She leans back down and asks me if I’m ready. I nod and she pats my bum. The dog jumps up and my heart starts racing. He starts humping and i feel his thing rubbing against me. I spread my lips and hes suddenly fully inside me going to town. I scream into the pillow and my aunt hugs me and tells me it’ll be over quick. I feel warm squirts fill my belly as the dog slips out. My aunt kisses my head and says goodnight.
