Della had been going through that transformation which changes young girls from innocent children to young women. Don wished her mother had been aroun... to guide her through those changes, but Ellie had been dead four years from cancer. Fortunately, his sister, Celia, had stepped into the breach when only an older woman's counsel would do.So, Della had coped with the physical changes she'd gone through, when her breasts had begun to fill into tennis-ball sized handfuls, topped with perky. I told her how exciting I found her unusually long nipples. ‘Breast feedin’ babes, just breast feedin’,’ she said. After a while she manoeuvered on top of me and dangled her massive tits in my face. I sucked them, then moved her up so I could taste her pussy. I started off gently licking her, then sucking her clit. She was very juicy and my face was wet. I loved it! Soon I was hard again as I sucked her cunt. She started jerking and cumming so I kept going a while longer, before gently. Still, they didn’t travel easily. Emily had taken a bus home for Christmas and again rode the Greyhound back for the new year. She had repeated the ride when school ended for the summer.When she arrived back home her family was, of course, glad to see her. Her friends from high school still acted as they previously had as did others in the area. Yet somehow things seemed a little different. It wasn’t exactly that Emily didn’t feel that she belonged here any more. Not exactly that, but something. I strapped her hands to head board of the bed and her feet to bottom. Now with her legs spread tied up she was helpless. Abuse me she said use me as your slut. I quickly took my hard cock from my trousers and rammed it into her mouth as deep as I could while pull her head towards me. She gagged and I could feel het struggling for breath I pulled out and she manage to catch her breath. Over and over i pounded her throat it felt so good. I strip naked and climb on the bed I spread my legs over.
