I am 13. Just my grandpa and I are staying down at his shack at the moment. I've been sleeping with no clothes on for the passed few nights because it feels better and my grandpa doesn't come into my room much, so he wouldn't know. But this morning I accidentally slept in so grandpa came in to wake me up. I had morning wood (an erection in the morning that is caused in your sleep) and I had kicked the covers off during the night so I was laying there naked, with a hard-on (how embarrassing!!). Grandpa quickly went out of the room and we weren't talking because it was awkward. Then later on today I was wanking off in the bathroom (which doesn't have a lock) when I thought my grandpa was outside. He walked in just as I was ejaculating and groaning with orgasm. One day doesn't get much more embarrassing than that!! How unlucky. My grandpa and I haven't talked for seven hours now. What should I say to him?
