We got along well, as well as most brother and sisters do, butwe usually end up arguing whenever I'm forced to watch her while mypartners aren't aroun....That happened this Halloween. It was on a Saturday, and my parents weregoing to the Bahamas, because they had won a contest and the tickets weregood only for that weekend. That meant I had to take Brittany Trick-or-Treating, and what was even worse was that she was going to a costumeparty at her school on Friday night. I wasn't happy about. I was having trouble making sense of what someone had entered, so I asked Donna if she could take a look at it. She came out and saw me sitting in the chair at the terminal.She asked, "Where am I supposed to sit? On your lap?"Now here's where a snappy comeback would have worked. But..."Oh um, sorry, sit here." And I got up. She sat and concentrated on the screen. My concentration was split between looking over her shoulder at the screen, down her blouse and trying to read the tag on her bra. ? If nothing else she could findsomeone to talk to.? She wasn?tinterested on screwing around but the loneliness had become more than she couldbear and her friends just didn?t get it.?She logged on and filled out the profile making sure that she checkedthe boxes that she was looking for friendship and talk only.? She got a couple of emails from some guys, but they wereobviously players looking for one thing only.?She just ignored these idiots; it just wasn?t what she was lookingfor.? A few. “Fuuuuuhhhk!!! God damn it!” she yelled as she had an orgasm that easily. Her pussy stopped contracting right when I got in a good position to see it.“Awwww, how cute. My lil sis came that easily?” I teased her“Shut up and do it again brother!” She said with a mad look on her face, waiting for another.“Excuse me sis, but I think I’m in charge here!” I rubbed the slit of her pussy when I started talking, and pinched her clit lightly when I finished. She moaned loudly and started gasping for.
