That night, I slept soundly thinking about the two teens waiting for my explorations with their older sister watching carefully to save them from havi...g a baby from unprotected sex. It reminded me of my earlier years with all my sister’s sexy friends all looking for a similar arrangement using my willing cock to give them the experience they needed to enter girlfriend and boyfriend relationships with the confidence my tutoring sessions provided with my sister’s blessings.My sister called me. I explained to Mark about my arrangement with his sister and that from now on she was mine and that she could expect to be doing some very interesting things, mostly things that would generally be described as perverted or disgusting, just as his parents would also be mine and performing similar acts. If he wanted, he could join her and his parents in obeying me completely or he could go home and we would carry on without him.In a quiet, subdued voice he then asked some vague questions and I. But we still did not break the kiss. After almost 10-12 minutes the kiss broke and we hugged each other. What an amazing feeling it was. She was in my arms after 3 months, her heartbeats were fast and mine too.I made her settle on the sofa and I went inside the kitchen and brought her water. She was just looking stunning and on top of that her little messed up hair gave a stunning look. I was just mesmerized watching her. She was smiling at me and kissed me and said, “I am here for you stop. Alexa looked at herself in the mirror, still in her small blue crop top and tight black shorts. She was flat and athletic but my best friend had a really cute face. "At least that's the worst thing you have to complain about! Someone broke into my locker...and stole my panties. Gross!"I widened my eyes and looked at her, "Seriously?" She nodded. "That's seriously weird. Maybe it's all connected haha the book goes missing at school last night then panties. What's next? A stapler?"Alexa frowned.
