Teasing her with my mouth and tongue, with every kiss she let out another moan. I got to the top of her thigh and the scent of her arousal drew me int... her pussy. I started licking her outer lips trying to clean up all her juices, she was soaked. I moved my tongue up to her waiting clit. Flicking it with my tongue and sliding two fingers inside her, finding her g-spot. She started to thrust her hips up and down on my fingers, she pulled my head into her so she could grind her clit on my mouth.. That will be up to you. I said it wouldn’t get as big as yours would it. He said no. But added he was a lot older and a lot bigger than me. But with time as long as we keep playing with it, it could get bigger than his. Oooo! I said. I’d really like that. He then told me it would be my job to find another young boy and turn him into a man. I was thoughtful for a minute. Uncle then said I would be like a teacher. And I said. But I don’t like teachers. He then said. You like me don’t you. And I. I had never felt so horny ever!! my cock was rock hard, even though my sister was no longer the sexy shape she was back in the 80's. The very thought of licking my own sisters cunt was the biggest turn on ever.Sarah stood up and removed her jeans and t-shirt and quickly removed her bra, her large boobs bounced on her chest, her nipples erect, she was obviously as turned on as I was. I started to undress too and got down to my boxers, my hard-on obvious to Sarah, she stroked my cock through my. She was squeezing my balls and sucking me deeply and the vibrator was going up her arse a good 5 inches, whilst she was taking all 8 inches of the dildo.When I could hold back no longer I gave her a very brief warning,"I'm cumming," and then shot my load into her mouth.Kathryn continued to buck up and down on the fake cocks as my spunk started to ooze from the corners of her mouth.I finally pulled both out as she moved her head away and there release was hers, as a long stream of cum squirted.
