My gf’s sister was a stripper and she had a collection of satin thongs. She knew I would borrow some occasionally to j******* with. Something she didn’t know was that when she was snoozing near by, I would get myself off without getting caught. Until one day, she finally figured it out and almost caught me in the act. I decided that I needed to be bold and I pulled my prick out just within her reach and stroked it for show. She was surprised, but still reached for me and licked her lips. Pulling me closer, she kisses just the tip and strokes my b****, then s**** me gently into her mouth. I was about to bust a nut before she got an idea of my mischief. Her exceptional mouth skill made short work of my nut and she swallowed everything I gave her. Now, I can masterbate in front of her whenever I want and she sometimes fingers herself while she watches me.
