I'm thirteen and I know almost nothing about it. Maybe I'll ask Donnie.So, the next afternoon, after school, I walk down to his room, the door is open... I peek in and there he is at his computer."Hey, Donnie, what's up?"He jumps a bit and changes screens, a sure sign he was looking at porn."Oh, hi, not much. What's up with you, Sis, anything earthshaking?" Nah, not much, just a sex-ed question for you." You got the expert." Do you masturbate?" Is this a joke?" No. They talked about boys doing it. I started to scan through her current and saved emails then her sent emails where I found most of the information that I needed, there were a lot of emails between her Jerry, Jenny and a few recent ones to Jerrys brother Tim, What Amanda had told me about the start of the affair with Jerry was correct but as I expected it had not been a spur of the moment thing as suggestive flirting had been going on for a few weeks before, then after it began some very graphic stuff had been exchanged but. "Looks like you're going to need a spanking, you didn't finish putting onyour uniform" He said as he sat down on the oversized princess bed andmotioned for me to lie across his lap."But I'm wearing everything that was with the uniform" I said like achild getting caught stealing cookies."Those shoes and that dress have locks on them, you did not fasten thelocks. Therefore, you are out of uniform. You are also not wearing theproper undergarments, but we?ll get to that after your final step. ..' Helplessly I whispered as silently as I could '...please, don't fuck me...' HE said '...make me believe that you mean what you say, draw it out...' I shook my head as his massive tool probed deeper into my outer anal sphincter muscle ring '...pleeeaaassseee, don't fuck meeeee....' I pleaded. Just about this time his enormously huge penile glans plopped into my anal cavity.Secrete Sex... I buried my face into the pillows and muffled my agonizing cry 'noooo,take it out, please take it.
