Let’s get to the story. Alka is a year elder to me. She had completed her first year and was visiting us with her parents for a competitive exam.She...used to study until late at night and I was also a late night guy. So, we shared the same room to sleep while our parents slept in the adjacent room. Since we were really close as siblings, the thought of us having erotic desires for each other never crossed our parent’s mind. However, fate had other plans. That night I was feeling horny. We slept. Harold Tunny was 73 years old and lived with his 78 year old wife Angela in a cosy little retirement home, over the course of their lives they had made some good money and could have stayed in their house which was rather spacious, but as they got older they had made the decision to sell it and move into a good home where Angela could get lots of care that she needed for her arthritis.Harold, or Harry as friends knew him, was still in pretty good shape for his age, well by that I mean he still. And she kept her gaze leveled at me.I looked away, ashamed. Missed the tip-off. And lost the game, fifteen minutes later.I knew what that gaze had been saying. You can’t make yourself better by making other people worse.We met after school that day. Mercifully, she didn’t mention the game.The afternoon’s experiment was about distance. By having Angelina step a little further away after each command, we worked out that my voice was effective to about ten meters, at least on a playfield covered. So when Tiffany bounded into the kitchen dressed for school, I gave her a big grin.“I hope you’re not burning breakfast,” she said, stopping before me, a huge grin on her face.“Trying.”She threw her arms around my neck and gave me a quick kiss on my cheek. She pressed her body against me doing it, teasing me with her developing curves. My dick ached in my slacks. Then, after a few more burning heartbeats, she broke away and flounced to her seat at the kitchen nook.“It doesn’t matter if you do.
