It was impossible to not notice Duke's massive dick, it was a huge black phallus which was as thick as it was impressive in length. When he positioned...it's head against my loosened hole. I tried to squirm away but he slapped my ass and held me down."Hold still bitch," he said and pressed it firmly against my butt. I felt intense pressure as it broke through the sphincter and beyond into my rectum. It was intense, not so much because of the pain but because I had been entered by another man's. Not really washing himself, just kinda shuffling awkwardly, giving me nervous glances. Ok, I get it now, I understand why he's been following me. So I walk to the towel rack, take off my towel and face him dead on:I swear his mouth dropped. I smile, walk by him really close and say "hi" before turning on my shower and letting the water run over me. My back's to him but when I turn around he's facing me - tanned skin, pretty much hairless apart from a small tuft of hair above his little. Wow! It hurts but the hurt was not actually a hurt but a nice feeling. I used to start getting wet and he used to send his finger deeper into my pussy.Now he used to shake it in and out of my pussy and I used to get wet and wet and wetter. Then I asked him about sex and he took out his dick from inside his shorts and it was big thing. I liked it and used to hold it so started to hold it and saw it too now. Then he said take and suck it like a lollypop and so I did that and liked the taste after. I jumped at the chance. Lilly felt abandoned by her husband and the rest of her family was gone. Izzy told us we'd be our own family. Sisters forever. We talked it out and agreed that if it was okay for one sister to be in love with her brother it would be okay for all three. What was good for one was good for all. We promised that we'd do everything together. Lilly wanted babies, so we agreed to have at least one each. We'd share the man we loved and no one would be jealous of the others..
