Me and my brother are some very curious beings. We frequently look through our parents things while they're not home, out of that mad curiosity that drives us to pick the madder choices. This time we found their sexual toys: multiple dildos, very big ones, sexy lingerie, cock rings, vibrators aaand... a box full of Viagra pills. I challenged my brother to take one, knowing this will result in a massive boner, and at first it seemed we're doing it just for fun. He took it and in about 10 minutes his cock started to react at the pill. Without being horny beforehand, he suddenly was, and the fact that I didn't want to stop touching his cock didn't help much! :)) I started to rub it, insisting that we're just having fun, casually, without weird things being implied... like him being attracted by me or anything like that! It became quite sexual from the moment he wanted to see my Big Boobs, "just to see if he becomes harder". I'm up to experiment and I do not have any moral boundaries, so sucking my brother's cock appeared like a great idea at the time! He was a little bit reluctant, we're related and so on, but wanted it for sure. In the very moment I put my mouth down there he started moaning and his cock was throbbing with pleasure. After sucking it for a while he confessed that this never happened to him before, he had sex with girls but never received a blowjob. I did not believe him first, but then I realized I'm giving him the first blowjob of his life and I put all my efforts into making it an unforgettable experience. My DeepThroat skills helped, he was amazed and asked me to do it again, and again! Well, I thought if we're already doing forbidden things we might as well have sex, sex isn't more serious than a blowjob, plus, I wanted to have my part of fun! He has a huge cock and it felt amazing, it was pure intensity, from the beginning to the end! We fucked doggy-style for a while, I had two orgasms, then he fucked me laying on my back and I came two more times! I had four orgasms in a single sex session, unbelievable! He was near many times, but I just wanted more fucking, although after giving me 4 orgasms he couldn't hold it anymore and came all over my big boobs and neck! It was a big, warm load
