Lisa was a very attractive woman, a redhead with the classic freckles, a smile as wide as the sun, and pale skin. She had to be careful not to get bur...t in the sun, but she looked startling out at the pool, more so topless, when you could see a few thousand extra freckles. I had to admit to having taken a good look at her nipples a couple of times. Don't get me wrong. I'm not remotely lesbian. It was a professional interest of sorts. I have a set of small insignificant nipples on appropriately. "Mmmm how is my lover today?" She asked softly.I moved away from her. "OK, sis? I'm not your lover. I'm your brother."Her eyes darkened. "No. You are my lover. Aidan have you forgotten how I can destroy you're reputation? Come on bro I thought you were smarter than that."I knew she was right but having her call me her lover just sent chills all over me. "Fine whatever."She put her arms around my waist. "Can I have a kiss?"I leaned down and gave her a quick peck on her lips. She groaned. "Oh! I. He took out his fingers and placed the head of his cock right at my hole. He applied a little pressure and slid in a little bit. His fat head was stretching me good. It kinda hurt a little bit but it was an "oh my god gimme more" kind of pain. He started rocking back and forth into me. And then the head popped into me completely. I groaned and grunted in ecstasy. It was amazing but I needed more."Come on baby. Fuck that ass!" I moaned. He rocked back and forth some more. Going a little deeper. The game, or our game as she just called it, was challenge that I was playing shown to me in the past by one Dominatrix. The rules were simple. I had to wear some kind of underwear or my shorts, something like this, and I had to orally please my lady until she reaches an orgasm or two. During this time I was not allowed direct stimulation to my cock. If I managed to create a smaller wet spot from my precum then I had the privilege to cum. If the spot was large then I was denied from orgasm.
