I was sitting on the couch doing some homework when my younger brother, Mark, came home. He slammed the door and stormed through the living room, “hey! dad would not like you slamming the door like that!” I yell at him. “Shut up and mind your own damn business!” he yells back from down the hall just before his door slams. “That boy needs to get laid…” I think to myself.
After a few minutes i think to myself “What the hell.” I set the computer to the side and get up to see what is wrong with him. I knock quietly on his door and he replies with a sharp “What!”
“I was just seeing what is wrong.”
“Nothing! go away and leave me alone.” he yells impatiently at me.
I walk back to the living room thinking, “he’s in there jerking off…” I go back to finish my work and give him some time alone.
It took me a couple more hours to finish up and I decide to go get ready for bed. “He still has not come out of his room, he must really be upset… or he is rally working it.” I muse as I walk by his closed door on my way to the bathroom.
I finish my shower, wrap a towel around my slim body and walk to my room. Before I step through my door I take a look at my brother’s door. “He has been so moody lately… and struggling socially.” I think to myself. Admittedly, he is not a bad looking guy, he is just a bit abrasive.
“What the hell…” I walk towards his door and slowly open it. I peek in the dark room and he is lying in bed. “mark” I whisper quietly. He doesn’t even stir, so I step into his room and shut his door. I walk over and stand next to his bed. I feel butterflies in my stomach, I cannot believe I am considering this, but if it helps keep him from being a moody asshole I will take one for the team, so to speak, and it has been a few weeks since I have gotten laid myself.
I slowly pull his cover down, hoping to not wake him just yet. I put my hand on his stomach just above the waistband of his boxers and slip my hand into them. My fingers run through his course pubic hairs and I quickly find his cock. I wrap my hand around the shaft and it is a decent sized one. I slowly start to stroke it and feeling it grow larger. “damn, he’s packing a large one.” I think aloud. I open the buttons on his boxers and pull his cock through the opening stroking him some more. I bend over and slowly take him into my mouth. I gently suck on his head, feeling precum in my mouth. He starts moaning a little bit and moving his hips to my rhythmic head bobbing.
I let my towel fall down and I reach between my legs and start rubbing my already wet pussy. I slip two fingers inside me and start fingering myself hard and start matching speed with my mouth. It’s not to much longer and I feel Mark cum in my mouth. I quickly swallow his load and pull the blanket back over him.
I walk back to my room, and leave my towel behind. I lie back down in my bed and continue my own self abuse until I cum. I Hope when he wakes up in the morning that he will be in a better mood, otherwise I will have to do more for him tomorrow night, a prospect I am not completely against.
