When I was around 10-14 I owned a mid sized black lab, well he owned me. He may have been mid sized but his cock was about 10 inches. He would sleep in my room and I would make his cock hard 1st only because it hurt not to get his humping out the way. Once he was done humping I couldn’t get his giant cock in me fast enough. I would fuck him hard for as long as I could then I would love leaving him inside me while he finished cumming, he came a lot. So much and I could feel his squirts everytime. At times I would feel like his bitch as I was underneath him letting him completely drain inside me. I would rub his balls to make sure I was getn it all. When he would try to pull away I would pull him closer and keep him inside me even longer. The times I would suck his cock I would swallow for him and that made me feel even more like his bitch.
