Date with my sister

Since the time my sister was 15 and started fooling around with guys, she has told me everything. From her very first blow job, to all the times with her girlfriends. One day I jokingly tried to talk her into “practicing” her blow jobs on me but she obviously said no and laughed it off. I have often had fantasies of her and I going down on each other, mutual masterbation, and sex.
The day she came upstairs naked, these fantasies multiplied and became uncontrolable. I was hoping that she was home alone (which she wasn’t) and I would have taken her down stairs to her bedroom and start softly kissing her and carressing her voluptuous tits. I kiss down her neck slowly and work my way to her pierced left nipple. I take the nipple ring in my mouth and slowly and gently start sucking and licking it. I lay her on her bed and move to her right tit and start working her nipple with my tongue. I start working my way down, kissing her chubby belly and teasing her. I kiss down and around her pussy, but I never touch it. I kiss down her right thigh, behind her knee and to her feet. I then pick up her left leg and start at the tip of her big toe and lick her all the way up until I can smell the sweet smell of her now dripping wet pussy.
