His first time ANAL - When the stepbrother is on the stepsib

I thought I couldn't believe my eyes when I saw this silicone ass lying on the bed. On closer inspection, I realised that a hole had been cut in it. Suddenly he was standing in the room and was super shocked that I had discovered his homemade sex toys. I asked him what it was all about... he was totally embarrassed, but then he came out with the truth. He wanted to practice anal sex for his first time, because his girlfriend wanted him to fuck her in the ass - and he'd never done it before. I felt a bit sorry for him, so I made him a suggestion: why not fuck my ass and I'll show him how to have proper anal sex? He thought I was taking the piss at first, but when I spread my ass, he knew I was serious. Of course he didn't say no and I was able to show him exactly what to do. He was good - really good - and his cock was mega fat. He fucked my arse thoroughly and was also allowed to squirt into my open arsehole... as a reward I sucked his cock nice and clean. :)
