I thought nothing of it - small parcels would often arrive unexpectedly - until I checked my email, finding a message notification: Mistress had sent ...e something! With my heart racing, I clicked the link - half-expecting to find Mistress finally dispensing with me entirely, or at least reminding me that I had promised to have a webcam for her by now. Instead, a simple note: 'slave. the parcel is from me. collect and open now.' Unlike a regular e-mail, now I had opened the message, Mistress. In between her moans Kelly kept telling me stop and that it was wrong. I stopped kissing her and told it was fine. I moved Carlas hand out the way and positioned my cock next to my sisters virginal pussy, placing the tip just on her pussy lips, Carla llied down next to Kelly kissing her gently on the mouth, I could feel a lot of resistance as I tried to push my cock into my sisters pussy, Kelly winced and turned from kissing Carla. reaching up she put both hands on my shoulders and moved her. I begin wondering if I’ve forgotten some anniversary or something she is trying to celebrate, but no, I know better than that; this is just how she gets her kicks. I go off chasing the guy who ran me over, and nab a nearby bike to follow him as she slips my dick through the hole in my boxers with nothing but her tongue. She drops her lips around my dick and slips her tongue down along the side. Her head rises and so too does her mouth, but she keeps her tongue pressed against my dick, then. "So about last night." Carly started. "It was great." She whispered. "It was the best night of my entire life."It was the words that Melanie had been wanting to hear but she could sense that "but" coming next."But I'm so confused." Carly admitted with her head down."I don't want you to feel like that, Carls." Melanie said to her. "What can I do to help?"Carly looked up at her. "I don't have a clue. I was coming here to tell you that I think I may be bisexual but on the way I was thinking about.
