I ended up staying at the house of my childhood friends, twin sisters, whom I hadn't seen in a long time. They seemed to have learned naughty things since they were little... They fought over my dick and kept begging me for sex!! When I got one of them to give me a blowjob, I had to get the other one to give me a blowjob too, and when I tried to insert it, they said "That's not fair! Me too!" and inserted it raw... From start to finish, the twin sisters kept me in control, and I had no time to rest as they sucked out my sperm over and over again for a whole day!!
