Our parents had been out of town that week. I was watching a romance drama on tv with my sister when I said something really dumb. My sister is a beautiful woman. Petite, with small breasts. Wavy brown hair, and in good shape, with what I now admit is a shapely ass.
"Oh I wish I had something like that!" She said. "It's been so long!"
"Has it really been awhile? Didn't you have a guy, Jim or something?" I said.
"Chris, that was ages ago. I haven't been with a man in months and months!"
"Damn you're so hard up I bet you'd even fuck me!" I realized as I said it what a terrible joke it was.
"Are you... suggesting I'd have sex with you? My big brother? Is that a joke? Or are you really hoping you have a shot with your own sister?" She said, with a smirk.
I stammered at this, but thought it would be funny to press harder. "Yeah, you must be desperate for any dick, even mine. In fact, I think you especially want mine."
"Is that so? I think you just want me to touch you like this." She said, catching me off guard as she started rubbing my cock through my pants. "You like that, don't you? You like your little sister's hand on your cock."
"J-Jess, what are you doing! You really were desperate!"
"No, I'm just teasing you. I could never enjoy this, you're my brother, don't be gross. You're the one getting hard at your little sister's touch."
"You're just imagining things, sis! I, uh, think it's time we turned in for the night." And with that, I pulled myself away and took off to bed.
"You can lie to yourself all you want. We both know you're the one that enjoyed that!" She said. I tried to pay her no mind.
I wasn't hard. I definitely wasn't hard. She was just saying that to tease me right? There's no way my own sister could get me off like that, of course. I turned in for the night. Such a weird night.
I wake up after a night of half-remembered strange dreams and head to the kitchen for coffee. Before I can make my cup I am greeted by my sister's panty-clad ass as she fishes for something to eat in the fridge. "Put some clothes on sis!"
