Your older brother is standing at the door

"Damn" you hear a voice coming from your door

"Christ Mark! When the hell did you get in?!?" You clumsily reach for the covers as if covering your body would prevent your older brother from watching the show you just put on. You have to admit, though, that having your older brother watching you does turn you on, even if you are afraid that he will be grossed out. You've always had this thing for Mark. He's 23, five years older than you, and he's inherited the manly traits in the family. He is your height but is definitely much more muscular. His abs are rock hard and his pecs look like they were taken from a greek statue. He inherited dad's square jaw and jet black hair, while you got mom's soft features, baby blue eyes and dirty blond hair. Mark left home and went to an out of state college five years ago. He occasionally came home to visit, but you had no idea he was coming this time.

"I got in late last night and slept in the guest room so I wouldn't wake you up. I just came in to borrow some toothpaste." He answers as he sticks his toothbrush in his mouth and lifts up a tube of toothpaste. He is still wet from his shower and is wearing nothing but a towel around his waist. He must have seen you jerking and coming because a tent is showing up clearly under his towel.

"That was quite a show you put on little brother, even turned me on." Mark says as he approaches you, dropping the toothbrush and paste on the floor. You are still laying in bed and are extremely turned on as he stops right at your side, his crotch standing at face level. He grabs your hand and puts it on his crotch, inside the towel. You can feel the warmth of his erection, and instinctively wrap your fingers around his beercan-wide cock. "See?" He grins staring down at you.

Holding your hand on his cock, Mark leans over and whispers in your ear. "I always new you were a cocksucker, and I could tell you had a thing for me, you've always dreamed with my cock...well, today's your lucky day."

As you sit down on the bed, opening your legs so that your mouth is at your brother's cock, he lets go of the towel and it falls to the floor. His cock is now staring directly at you, its stench inebriating.

"Get me off little brother. Suck me off or I'll fuck your face until I cum" Mark warns you. You lick your lips in anticipation as you start stroking your brother's cock with long full strokes. You decide to get as much pleasure as possible from this once-in-a-lifetime opportunity and start by licking his nuts. You push his cock up against his stomach as you take each testicle into your mouth, rolling it around and covering it in saliva.

At this point your cock is hard again, you can feel it rise and wrap your hand around it, stroking it slowly as you continue savoring Mark's nuts. You let them out of your mouth and continue your way up his dick. You trace the largest vein from the base of the cock to the head with the tip of your tongue, shifting your hand from his shaft to his balls, and play with them. When you get to the cockhead you taste the drop of precum that has formed at the piss-slit and let it stretch as you pull away from the cock.

Mark has tilted his head and is silently moaning, his mouth agape as he runs his hands through your hair. He is no longer a brutal top but a little kid moaning for his cock to be sucked, he needs you to give him pleasure. "Please, bro, suck it..."

You want to tease Mark until he can't handle it anymore and decide to pay attention to other parts of his body before returning to his cock. You move up from his cock, licking and biting on his happy trail up to his abs and all the way to his nipples. You play with each of them and bite each one making Mark gasp in surprise and pleasure. Your hands travel up and down his back as you get to his neck, biting and sucking all the way to his lips.

You feel more aggressive and kiss Mark passionately, standing up from the bed and letting your cocks grind against each other as your hands can't seem to get enough of his body, gripping his ass and then moving all the way up to his hair. You both hit the floor, you lying on top as you continue kissing. While you grip him to the floor, you lean into his ear and whisper "Say it, tell me you're dying for me to blow you". You grind your cock into his and he promptly responds "Yessss...fuck, I need it bro, make me cum"

Losing no time whatsoever you open his legs and get between them, taking his cockhead into your anxious mouth as your hands travel up and down his torso. You both moan, Mark's eyes rolling back as his cock enters your mouth. You wrap your lips tight around his head as you put it in your mouth. Your tongue comes into play and swirls around the hot head, which now oozes precum at a regular rate into your mouth. You locate that sweet strip of flesh which joins foreskin and head and lick it hard.

Mark can't take it anymore and he starts arching his back in pleasure. His hands are now gripping the back of your head and thrusting his cock down your throat he forces your head down on his meat. You've had a lot of practice and are a natural cocksucker, and have no trouble whatsoever getting used to his rhythm, letting him fuck your face hard while enjoying every inch of his meat. Every once in a while Mark takes out his cock and rubs it against your face, playing with you as you desperately try to get your mouth around it.

Your hand now furiously pumps away at your own cock as Mark speeds up fucking your mouth. You are both covered in sweat and will definitely need another shower. You can feel his muscles tensing up as he wraps his legs around your back. Mark's balls start to contract as you feel his orgasm nearing. You are right on the verge of cumming yourself and with one last thrust your ow n juices start to spurt uncontrollably as Mark buries his cock entirely down your throat and you feel his cum shooting down your throat. Both of you have to keep your volume down since the door is still open and your parents are downstairs waiting for you.

After what feels like forever you feel Mark's cock becoming flacid again and take it out of your mouth, lapping at the head once to taste your brother's cum before you go.

"I always knew you were a natural cocksucker but I never figured you were this good. We should get downstairs before mom and dad start wondering where we are"

You lick your lips to make sure no cum is left and decide to go downstairs...
