Nervous as hell I nonetheless did as he said and tried to relax my reluctant butt. I took a huge breath and exhaled slowly as by body dropped its last...futile defense. The big, bulbous tip slipped past my sphincter and his entire cock sank to the hilt in the hot, soft confines of my RECTUM! The sensations of pleasure were like nothing I had ever imagined! We both let out a loud gasp. “YOU OK BOY?! “ he asked starting to hump me. “Yeah” I just managed to say. “You love this too don’t you? YOU. He looked back and winked at me and then walked into the bathroom, greeting them and then saying they could talk and watch something while the two other girls talked. I sighed, damn not good. Once we made it to the guest room, she pushed me on the bed and then jumped next to me."How fucking long!?" I looked down and blushed, "Since I was 13..." "You never fucking told me!" Of course not! I didn't think you'd understand! Why would you? I mean you are straight and at times I thought of telling. I nervously said I don’t know, he continued to tell me just to go on and touch it. Eventually I grabbed hold of it...the thickness of it filled my hand...I felt the strong pulsations coming from it and felt the sticky pre cum that had dripped down the tip. I began stroking his thick black cock...eventually moving my hand faster and faster. This led Toni to move his hand higher and higher until eventually he was groping my little white cock in my panties. After a minute or so of us touching each. What was surprising was when she turned out to be pregnant and nine months later gave birth to a litter of six adorable puppies that could speak english in four months and was as intelligent as any human. I had found my human female and now my six offspring had to go out into the world and find their mates. They were half males and half females and being adorable were quickly adopted by humans. The three male puppies went to three young attractive women. Two of the female dogs went to two young.
