Then another emotion filled her as she opened the door to step out, it was one of excitement. 'So Alex wants to watch his little sister with her lover... I bet he'll be as hard as a rock,' she concluded.Gwen padded down the hall to her brother's room again and knocked on the door, she was told to enter."How do I know you'll remain silent if I let you watch us?" Gwen asked.Alex swivelled in his computer chair and faced her."Have I ever lied to you?" he asked.Gwen had to admit that he had never. My speedo was fucking rock hard and straining against the lycra of my Arena speedos. "Holy shit Dave, that was amazing!!!!"I sat back down on the couch and Alex was still slightly out of breath."Do you mind if I put some speedo porn on and I can rub one out myself mate?"Alex had no objections but I told him to go clean up and I was sure there was a clean pair of speedos in my bathroom. As if I wasn't hard enough as it was after sucking off a str8 guy in an AussieBum speedo but Alex returned to. So after almost licking and playing it for around 15 minutes I started going down. My tongue was licking his anus. He was almost half dead by the excitement and I loved to tease him, it was clear that he was never given this kind of a pleasure. He started sweating profusely and moaning. Almost after 5-6 minutes later, he took be by my hair and started kissing me and kept on saying me thank you. He then wanted to touch my boobs for which I said that.I would give him pleasure now and his turn. I went straight for her bag and rummaged through it and found her panties she had worn over! Unfortunatly, she had taken a shower before comming back, and had also changed her panties, so they were clean and had no smell! I put them back and went upstairs to watch her out the window and jerk off. After relieving myself I went back out and kept Teadora company before she finally left. I was surprised sunday, when she showed up on her bike wanting to take a quick swim! I had of course told her.
