I turned over on my hands and knees and rubbed my clit..When suddenly Grace (my sister) walked in with no warning. “DAMN sis, what got you so hot?�...� I covered up quickly, but I was not quick enough. She laughed and sat on my bed. “I am guessing you saw me and Mike fucking huh?” I said, “How could you do that to mom?” “I know D. But honestly, he is the best fuck I have ever had. You gotta try him out, if it would make you feel better, we could share him. “ I was shocked. I couldn’t imagine,. She said no way and I said okay I’m telling Mom and Dad. Okay okay but promise me you will never tell them. She was almost crying so I said okay but you have to promise to allow me to watch you. I closed the door and sat on the bed and said okay I’m ready. She looked so upset and ashamed of being caught and now completely naked in front of me. She opened her legs again and fingered herself calling the dog to her. He immediately went to her and smelled her vagina and started to lick. Puberty's going to be affecting her in god knows what ways that we can'teven begin to imagine. The surgery's the only kind way to go. Thehormones she's taken for the past 3 years have completely destroyed thesexual organs so there's nothing from a male perspective to even considerI heard Mummy say and in a more reasonable tone of voice then askedAnnette couldn't she understand and see that too?There was a complete and sudden silence when I walked back into thelounge room and I could see that. She changed the channel.. From that minute she looks me with lust.. Her tits are erected easily visible from her nighty.. Finally night came.. I’m in full excitement.. She came at 10.. I closed my eyes.. But didn’t sleep.. She laid besides me.. And placed her hand on my thigh.. Came close to me and placed her head on my shoulder.. My dick erected and easily visible from my boxers.. Her boobs are pressed against my chest.. I’m seeing all these with my left eye little open.. Slowly she removed.
