When a pipe burst, it caused a family emergency, and the whole house was in disarray. At least the family isn’t going to have to stay in a hotel, but you were given an ultimatum: You have to stay in your brother's bed, or find somewhere else to stay.

Our age difference isn't that large, me being 21 and you being 19, but our relationship has always been rocky. Me being the "wild one" and you being much more reserved and nerdy. I can't say it's your fault, if anything it's mine. I've always treated you as if you were a child and I was too good to spend much time with you, always seeming annoyed with you. I've heard your arguments with mom for not defending you. She claims it's all in your head, but you're not wrong. More than once you've asked me why, and it just encourages me to become even more annoyed.

It’s after midnight, and you reluctantly enter the room with a pillow in hand, turning the light on. I sigh, "Shut the light please" as I turn my back to you.. Once you get into the bed and get comfortable, we find that the large comforter is more than big enough for the both of us.

Little did we know, the parents are pumping the heat in the house to make up for the lost insulation. It's absolutely stifling in the room. You look over at me. Since I'm still asleep, you decide to shimmy out of your clothes, wrapping yourself in a sheet. Finally, more comfortable. You’ve made a habit of sleeping naked. Wrapped up in your blanket like this, nobody will ever find out, right?

Early in the morning, I’m rudely awakened by the sunlight. With a frustrated sigh, I turn over. Never did I expect to be greeted by my sister's perfect little ass and the dimpled curves of your toned lower back. You had tossed off part of the blanket in your sleep, exposing your body to me. "Fuck!" I think, I had never known you had a body like that hiding beneath your clothes!

How am I supposed to resist that? I think as my hand slides into my boxers. Hormones pumping and not of my right mind, I begin carefully trying to relieve myself as quietly as possible.

It hadn’t crossed my mind that with the bouncy springs of my bed, you could feel my every move, able to tell exactly what I’m doing….

I hope you enjoyed the introduction! I've intentionally left it open so you could include your own ideas. Will you be disgusted? Or was this your plan all along? Will you try to secretly relieve yourself? Or will you join in? Will you tell me to stop? Or will you say it's fine and keep going? Is this the opportunity you've been waiting for to gain favor in my eyes?

If you're interested PM me any ideas you might want to include, or if you're satisfied with the current direction, you could continue where the prompt left off.
