I hate Paul cos he keeps looking at my tits but Siobhan is okay although she is a year younger than me at 13. But I am nearly 15 now. Paul is also 1... and I reckon he is a pervy little git, just like his Dad, my Uncle Thomas.All of us will be sleeping one side of the large pop-up trailer and my Uncle and Aunt will sleep on the other side. We pulled into the campground at night, it was one I hadn’t stayed in before and by the time Uncle Thomas pulled the camper into the site I think all us.

Our eyes were wide, and our bodies frozen half in fear of being discovered, half in arousal at the thrill. The front porch light temporarily blinded me, and I was glad that we’d had the foresight to recline the seat. I peeked over the bottom edge driver’s side window, and I whispered the unfolding. My stomach was churning, my balls aching and my cock growing rapidly. 'What the fuuuuuuuuh......?' I exclaimed as 5 rapidpire jets of cum exploded from my stiffened cock. 'Ahh there it is' laughed Mike 'but now its my turn' he grinned. I was done, my horn evaporated, my cock limp and then he started to thrust....... It felt weird, tingly, different, uncomfortable, awkward...... Mike was ploughing away and the sight of his sex face was disturbing and I wanted him to stop. 'Nnnnnng faaack, oh,.
