I have no doubt that slick wetness coats the knot and I stop rocking and begin to grind.There is a fine line between pain and pleasure and masturbatin... on a log it’s easy to cross over unexpectedly. A little pain can be a good thing.I imagine the picture from someone else’s eyes; a naked woman, her chestnut hair falling about her face as she holds this giant cock log in her hands and humps like a feral being. The thought of being watched sends me over the edge and I have the fleeting thought. It felt so strange but something burning within told me to continue; lust. I slid my tongue into her warm mouth and explored it, occasionally rubbing her tongue with my own. I then pulled back to breath and looked at my niece, sprawled out before me, waiting for me to make my next move.I then slowly slid my fingers down into her shorts and panties and slowly rubbed my fingers up and down her slit, I could feel her wetness and it excited me even more. I rubbed her clit momentarily before sliding. " I took the leash and walked our sub over to the bed. There I picked her up and put her on the bed. Kathy slowly rose up on wobbly legs and came over to see what I had in mind. I went to the gym bag and took out a vibrator and a huge dildo. Kathy looked at me with an expression of interest. I smiled and got on the bed with our little sub. "Now, pet, you're going to get ass fucked. You'll like that, won't you? Have you done it before?" She shook her head but she was smiling. So was her. "What do you know about how I feel?" Dawn asked as she pulled her head away from her sister and looked deep into her eyes."I feel the same way as you do about Lee" April admitted to her shocked sister "But me and him have taken things a bit farer if you know what I mean?" You mean you two have oh my god April!!" Dawn was stunned by what she had just been told, who wouldn't be."Twice" April said with a little smile."TWICE!!" Dawn shouted "Oh my god who else knows?" Stace and I think Kim" April.
