We were enjoying our coffee when Lisa started speaking. “We need to talk about this” she said. “Before we get too deep into anything”. I nodded, and listened. She said she had really loved having sex with me. And I told her I loved it too, “I noticed” she said with a smile. “But” she began, “I need to make sure we don’t do anything that will harm our relationship, we have always been close” she continued. I was a bit nervous now, half expecting her to say we couldn’t do it anymore. “I love you” she said, “but I will never fall in love with you, you are my little brother and you will always be. I hope you understand what I mean”. “I know what you mean” I responded, “I love you like my sister, and I feel our bond have grown even stronger now. But i feel the same way about this as you”. “Great” she said, smiling broadly, “I hoped you would say that”. “Does this mean we can have sex again?” I asked her. “Yes” she answered, “but we need to be careful, it has to be our secret” “Of course, I know that”.
A bit later that day, I went out to visit a friend. It was a beautiful day, with an even more beautiful start. I felt better than i had in a long time as I took my bike down to my friend. We met up with some other friends, and ended up biking to a small Forrest pond to cool off in the water. When the clock neared 2pm we split up, heading home for lunch.
When I home, i found Lisa on the balcony sunbathing. She hadn’t bothered to change out of her red bra and panties. She opened her eyes and smiled as I stepped out on to the balcony. I asked her if she felt like having lunch, but she said she was too comfortable to move. So I decided lunch could wait, stripped down to my underwear and laid down to enjoy the sun for a bit. I laid there beside her, watching her. And I felt the now familiar desire build inside me. I enjoyed the sight of her incredible body. Her ample breasts, flat belly, her curvy hips, long toned legs. I felt myself growing hard from the sight, and the memory of our morning together. I couldn’t keep my hands off her, I let my hands stroke over her breasts and belly. Feeling her warm smooth skin. She opened her eyes and squinted against the sun at me. “sorry, hope you don’t mind, you looked so sexy I couldn’t help it” I said sheepishly. She smiled again “I don’t mind, it feels nice”, she closed her eyes again but her smile remained. I kept caressing her. I was horny, but I also liked the idea of making her feel good. Her eyes still closed, she reached behind her back with one arm and undid her bra. I took it off her, savored the sight of her now free tits. Neither of us said a word. She silently enjoyed my caressing, and I enjoyed the feel of her skin. I paid special attention to her tits. I took one nipple between two fingers, squeezing slightly. And she let out a soft moan, clearly enjoying it. As I continued caressing her, I reached into my boxers. Took out my cock and started jerking. She must have noticed the change of my movements, because she opened her eyes again. She watched me jerk off while my other hand played with her tits. “can I fuck you again” I asked after a while. “mm sure” she said, she lifted her hips, took off her panties, and spread her legs.
