I let my free hand massage her chunky-ass, roughly. She began thrusting harder and turned her head to me. “You…(ungh!!)want some more…(Ooof)?”... she panted. Her eyes were so sleepy and glazed. She almost looked as if she were about to pass-out! Letting go of her as, reluctantly, I took the joint and had a deep pull off it. I held the smoke for a few seconds then pulling my fingers out her pussy. I flipped her onto her back, fell heavily on top of her, and smothered her mouth with mine. Blowing. Crissy's hips were jerking. Her small tits jiggled, her nipples feeling as if they were going to burst. "I'm creaming ... Christ, Tammy. I'm creaming your fuckin' knee." I feel it!" Tammy gasped. She jerked up her knee, smashing it against Crissy's cunt, and watched her younger sister's face twist into a mask of lust."Aghhh!" Crissy wailed, almost toppling off her sister's knee. "Jesus, Tammy. I'm so fuckin' hot!" My pussy, Crissy. Eat my pussy." Tammy was shaking, the inside of her virgin cunt. The other cot was perpendicular to the big cot. We watched tv till noon. Then she made some lunch and served me. She said she will have later. It was around 2 in the afternoon. I switched off the tv and started using a laptop. I had a lot of sex desires Since I was in 9th class. I read a lot of stories on iss by then and used to have all sorts of fantasies. I was lying on the bed and I made sure laptop screen wasn’t visible to her. I started browsing some porn and read some stories. She was. Lily still the inquisitive one asked if she was going to be punished, with that statement I heard an intake of breath from Natalie and Barbara, but no questions. But Lily wouldn’t let it go and asked, “Master I need to understand, you did not say one word to her about being bad. How does she know?”I just smiled, “Lily, your Mistress is very intuitive and I don’t need to talk to her, somehow she just knows. Now you have also been a little bit bad yourself. A quick moment of disbelief crossed her.
