I'm Jessica, a teen with mousey shoulder long hair, and blue eyes, returning from school that day.My Grandpa, Mike, is around 60, semi-retired from wo...k, and a close friend of mine, as well as a relative.'Hi honey' he says with a smile.We walk through to the livingroom, were he sits on his usual corner of the sofa, and asks 'So, how did your day at school go?' I reply 'ah, you know, just a normal school day, really.'I'm stood at the entrance to the livingroom, trying to decide if I should go. As she sat on him he and her groaned at the same time, as she bounced up and down on his cock he licked her nipples, then she grabbed the other lad and fed him into her mouth. After watching all this from the bathroom I was already naked and feeling my rock hard 6” I needed to get in on the action, I lubed up my cock and walked over to the bed. Kneeling on I teased Donna’s ass with my tool, she groaned, then inched my way in, she groaned real loud as I fucked her ass as the other guy fucked her. When I finally finished, I realized I had to clean up and get out of there. But I was so spent; I actually fell asleep for a while. When I woke up, it was about 3 am, so I had to use my underwear to clean up my jizz from the closet. I had to go slow so as not to be heard. When I finished, I tried to open the closet door quietly, but then I saw her move in her bed again. This time she was awake and moving with purpose.She reached for her drawer and I saw her pull out a vibrator. WOW. I went. God... She swallowed nervously. Glancing covertly around the bus, she wondered if there were any other subs or Doms nearby. A guy of about thirty got on and winked at her as he swaggered past. He was unshaven and looked a little dirty. Hmmm... she thought. I doubt he’s a Dom. I guess he COULD be though. Probably more likely to be in advertising or something. Maybe a music teacher... She smiled at her thoughts. Of course a teacher or artist could be a Dom, she reminded herself. In fact,.
