I don’t know why I was so blowjob horny that night but it could have been because we had gone swimming that afternoon. The whole family, including my brother-in-law, Robert. Robert is a decent guy with a bit of a gut. His office work limited his activities. Over the month he traveled some and worked a lot so I only saw him at dinner and over the weekends when he wasn’t playing golf. He tried to teach me the first Saturday but after losing 7 balls he thought I should try other sports. I had to agree. It just was not going to get better. So, I was horny and I knew I better lock the door before taking up my usual practice. With the door locked I turned on my computer and started pursuing my favorite sites. I like one that has a anal sex variety of movie clips. Some group sex are as long as an hour. I opened one that looked interesting. Supposedly the brother and sister were staying home with the parents gone for the day. The brother sees his sister in a skimpy bikini and starts getting Big Tits a hard-on. As his sister is laying out getting some rays the brother keeps spying on her hoping to get a nice view. As she is laying there she starts to massage her breasts through her top until she absently moves it down releasing her two beautiful and perfectly shaped breasts. He is now drooling and stroking his cock. Of course, it doesn’t take long before she is rubbing her pussy. She moves her bottoms aside showing a clean shaven perfectly shaped pussy. One any guy would appreciate. She rubs her finger up and down her slit until she finally pushes a finger into her vagina. He hears her moaning. He moans as his dick is hard and reacting to his sister’s moans. I am stroking my cock, all six and a half inches. Not too big and not too small. I am really enjoying the pornstars sight. Then her brother walks over and watches his sister with her eyes closed. She hears a sound and quickly opens her eyes to see her brother watching her and his hard dick in his hand. Her surprise turns into a smirk and she reached up and wrapped her hand around his dick. “If you’re okay.” I sat on the couch and we traded places. anal sex ”Don’t worry. Dag nodded, sympathetic. “Good. The tweaks I could make to my wife. “And what does group sex that have to do with us?” I asked. Shit, could he be right and that blowjob I am an exhibitionist? She had cute, sassy outfits when I saw her pornstars and always had a sweet smile. “Put Big Tits me to the trial”.
