It was a split second decision. I hadn’t meant to flash my brother… it just popped out… but I saw him look as I stuffed it back in. I noticed the look on his face and the bulge in his shorts as he got up.
He was going to the bathhouse to jerk off. To me. I felt a rush of excitement as I realized what I’d done to him.
Instantly I was on my feet following him. I wanted to watch. Or maybe help. I see couples going in there all the time, and nobody here knew I was his sister.
“Don’t lie to me, little brother. I know you look” She was whispering, our bodies millimeters apart. Her breath was warm, and I couldn’t keep my eyes off her lips. She noticed me looking, slowly licked her upper lip, and then hissed a sharp giggle from between her teeth. “I bet you’re horny now.” She now held herself in my shadow, looking up, biting her lower lip. Her blue eyes trembled. I felt her voice rising now, warming my neck, snaking around my throat. “I bet you want me, your big sister,” She hooked her index finger just inside the elastic band of swim trunks, “To get on my knees, right her on this dock, and push that thick throbbing cock into my mouth. And let you, my little brother, use my throat like your personal Fleshlight.” She giggled. “I bet you’d cum, just hearing me moan “little brother” while I slobber on your fat dick.“
I clenched a fistful of her hair, pulled her head back, lowered my lips to her neck, and lips grazing her throat, “And I bet my sluttly sister would love swallowing ever ounce of her little brothers baby batter.”
It was early and there were few people in the mall. I wanted to look at games, but my sister couldn’t help dragging me into a clothing store to try on some new tops.
She confronted me outside the store. “You were checking me out, weren’t you?”
“Can you blame me?” I asked.
She looked at my pants, then back up at me. “You know, girls get horny too.”
“Yeah, I suppose,” I replied, not sure where this was going.
“We’re both thinking about the same thing, aren’t we?” she asked. She looked at my pants again, then back up at me.
“There’s a family bathroom here,” my sister suggested. “I’m sure horny teenagers like us use it all the time. Nobody here knows that we’re related. You want to? I can keep a secret if you can….”
I couldn’t believe she would want to do it again, the way she coughed and spat the last time. I was even more surprised when my sister showed me her tongue. Had she really swallowed it?
“See,” she grinned, “I really can do it. But now I expect you to do it to me. No excuses now.”
- “Again? You just fucked me in my bed for an hour and now you want to do me in the shower too. You are the horniest brother a Gil can have. But ok then. You can take me in the shower. But only for 10 minutes. I need to get to school and you have to drive me.”
I used the spare key to sneak into my brother place while he was at work. He’ll get home to find the best surprise of his life, his sexy and horny sister wet and ready, on the pill and good to go.
