We have grown closer and closer through the years and it all cumulated the weekend after Lilly turned 18 when she fucked my brains out. (See the story... “I Love My Niece.”)Lilly has essentially moved in with me. She has her own room, but that is mostly for appearances. She usually stays in my room. As she puts it, “I want to return to my origins.” Laughing, she explained, “To the place of my 1st orgasm.”We have tried to keep things light because Lilly is going off to college. I want Lilly to be. The guard separated my naked bottom. With one hand, he fully inserted the 8 inch probe into my anus and deep up my rectum to its full length. I arched my back when he finally shoved it all the way in, and placed the wired end of the probe into a stand set on the floor to the proper height of my bottom so the probe would slide out of my ass. My penis now involuntarily pulsed. He noticed this and looked at it, and raised an eyebrow and then looked at my face. "You're masochistic." He whispered. Mom noticed the movement of my dick and said, “I’d like to hear you talk dirty to me some more Rasheed.”I blushed again, still not so comfortable with being so openly crude.“Go on,” added dad, “It’s all part of the fun.” He looked over at mom and said “Sheeza, you’ll have to direct him a bit.”Mom looked at me, and still with her fingers pumping her twat, she said “Rasheed, tell me how much you like my ass and pussy? Tell me how long you’ve wanted to play with it, and now that you are allowed. He placed his finger on the back of her neck and moved it all over her spine till he reached her ass crack, this made her shiver. He placed his dick on her ass crack and started rubbing it hard against her ass. She was dripping from her cunt now as he kept on teasing her with his dick inside her ass crack. He grabbed her ass and pushed it up, bringing her into doggy position.Her head was resting on the floor and ass raised up and she was ready to receive his dick. He brought a burning candle.
