Fucking my girlfriend's brother

This is based on a true story - Please leave your comments its only my third time writing a story so feedback is appreciated.

Some stats, I am 24 muscular, average length but thick cock, uncut, completely hairless, brown eyes, dark brown hair. Cody (not his real name) is 18, swimmers built, smooth, big long cock, piercing green eyes and dark brown hair.

So I have been seeing this girl who is still in high school, final year. She is cute and we have been having a thing but she has no idea that I am Bi. We haven't gotten around to discussing this yet. From the first time I met her brother I was drawn to him this guy barely legal, turned 18 two weeks after I met him, was cute as hell hair slightly in his face, a smile that would just melt you on the spot. But Cody was very shy, he didn't really talk much but I already then decided that I would make him my first virgin victim. So I kept coming over to my girlfriend's house and would see him and we would start saying hi and bye to each other and so on until we realised we both shared an interest in gaming and were geeks at heart. He came to my house with his sister once or twice and we had the usual banter one night about how sex was with his sister and what we like girls to do and so on, he said he also had a girl a few months older than him and that they were experimenting but haven't gone all the way yet since she worries his big dick might hurt her. 

I laughed it off, "Yeah right, no such thing as too big", "ummm hmmm" he said. Then as time went along we became good friends and I saw him once or twice without his sister there. Then one day I came into their house, and as I stepped into the hallway to his sisters room he came out of the bathroom just a hand covering his dick walking to his room, since he forgot his towl. The sight of his washboard abs, cute pecs, and a cock that was hanging below his hand gave me a semi, not to mention his cute bubble butt going up and down as he said "hi" and went past me. I knew I had to get that on top of me.

His mother then started mentioning a few days later that he is starting to give them some issues with his behaviour and that he is not focused on school college and taking life as a joke, but also that he is upset to not have a place of his own and some privacy. His sister affirmed that its because he told her that he is not sure if he is all for girls only and his mom would be devastated if he is gay or bi. I suggested to her that maybe he should come stay with me at my place a few days and I can talk to him and just give him some space, she said she will ask but doubts her mom will agree, being that I am older and more open to modern culture than them. They were a weird family and especially her and the brother seemed to share everything with each other, which was odd compared to how I am with my siblings.

I was lying in bed one night  when my girlfriend called me hysterically, saying that I need to come fetch him and talk some sense into him cause her mother just threw him out on the street after she caught him watching gay porn on his PC. I obliged and rushed to their house. There I found him sitting crying on the sidewalk in a tight shirt and his trunks only. I went to sit next to him and console him and told him to come with me, stay at my place and once she calmed down we will come talk to his parents in a few days. He got up and into my car I couldn't help but notice a sizeable buldge in his underwear and the streetlight just lighting up enough to watch his cute butt move to the other side of the car. I told my GF to tell her mom he is safe with me for a few days dont worry I will get him some clothes and whatever he needs, in more ways than one it later appeared, and bring him back once they are calm and we can talk.

We got to my house and he went in and fell onto the couch crying, being a cold winter night, I went to make us some coffee and got him a blanket to regrettably cover himself up. We started talking and he confessed that he thinks he is Bi and has become more attractive to guys despite him and his GF still fooling around. He started crying and placed his head on my chest and held me and I held him telling him it's ok I understand, I am the same but his sister doesn't know. He looked at me and just kept crying. After a while, he calmed down and I suggested that he goes and takes a shower and I will make us something to eat and get him some of my clothes to wear. He got up and went to the bathroom. "Oh, I hope you won't mind sharing the bed, I converted my spare bedroom to an office so its that or the couch," I said. Hiding the fact that I had a spare bed concealed in the closet of the spare bedroom. "Sure, you have done so much I really don't mind, it's so cold a cuddle might just be what I need" he replied, was he suggesting what I was thinking?

I got up and put some steaks on and made some salad and fries, while I was busy he called from the bathroom. I knocked, "Come in," he said. "Do you mind if I use your shower gel, obviously didn't bring anything." "Of course not," I said, looking at his now fully naked body standing in my walk-in shower, wet and hot, I got a hard-on and was so tempted to just rush in and take him. "Like what you see?" He said, looking down I see my tent in my pants "Ummm sorry man just been a while your sister has been so busy" I replied, "Its cool man I know". "But yeah use whatever you like in my cupboards should be some clothes and underwear for you once your done" "Thanks man," he said.

I went back to coocking, he got out dressed in a tracksuit of mine, that was a bit big for his smaller frame, but the thought of him in my clothes made me want to cum. We had dinner chatted some more about what he liked and if he every tried anything with a guy "I mean I like big muscular guys but never tried anything until now its less than a month ago I discovered that the guys is making me harder than the girls watching porn" he said. "So when we were swimming and stuff last week the sudden games in the pool?" I asked, "He it was an excuse to touch and look at you with less clothes on" he replied. "Well ok, lets finish up and head to bed, I still have work in  morning".

We finished up and went to the bedroom where he looked at me saying "Thanks for everything tonight I just feel so comfortable sharing with you and not being judged and dont worry I wont tell my sister your bi." " I would appreciate that man, and no worries my door is open for you anytime" (my back door I meant). He started stripping down completely "hope you dont mind I kind of like sleeping naked" he said. "No worries I sleep in my underwear though" I said pulling down my clothes leaving nothing but my tight black trunks on.

We got into bed and I switched off the lights and went to sleep, I got awoken later feeling his body right up against my back his dick pressing against my butt. I could feel him breathing in my neck and his hand coming over my body. He started feeling me up and down over my abs and pecs, slowly, gently placing his hand on my cock. He started rubbing it slighly, until he got the courage to put his hands inside my trunks and grab hold of my cock. I nearly moaned in enjoyment, but manage to let out only a slight sound, he stopped. Thinking he  awoke me then i just kept laying there until he started again his hands now reaching and playing with my balls. Without notice he pulls out and then starts rubbing his now, semi hard dick against my butt his hand trying to pull down my underwear he pulled it down slightly and pressed his cock against my naked butt but not far enough so he can reach my hole. Again he put his hand on my cock started stroking it and I let out another slight moan, wondering if its wrong to have this barely legal teen doing this to me, but it felt so good, my head instead of my brain my decisions further. 

I grabbed his hand and held it tight. He jerked "sorry I didn't mean to, just when I am sad I go horny, and I thought earlier you were sending me signals" he said in histeria. "Calm down how about I turn over and you pull down my underwear and put your lips around my cock?" "are you sure?" he replied. "If you are sure you want to do this" I said, "yes its my dream come true".

With that he went down and started licking the head and then my balls taking them and putting them in his mouth completely while using his hand to work my cock, its was so good. Then he started sucking me bit by bit going deeper, I started to grab his head and force him down, choking him a bit. "Breath, relax you can do it" he tried again but his throat just wasnt used to it and I let him go as fast and as deep as he could about two thirds was all he could manage. "Slowly I am gonna cum" and with that I pulled him off. "Did I do something wrong?" "No cutie but I dont want to drown you its my turn now" I said. With that I pushed him onto his back and went down quicky realising his GFs complaint his dick is easy 11 inches and thick I started with his head then playing with him edging him, not taking it all deep "I am close please dont stop can I cum in your mouth?" with that I took a deep suck taking it all the way in until my lips touched his balls. I was working it hard then suddenly I felt him spasm and jerk and grabing hold of my head forcing his cock to stay in my mouth as rope after rope of cum shot down my throat, I had to swallow some or my mouth wouldn't be big enough.

"OMG that feels so good" he said, I came up to him placing my body onto his letting his wet cock touch my, thats now leaking precum as our chests meet and I start to kiss him. "Do you like this" I said as we share his cum. "Yes, yes I do" he replied. "I pulled away slightly, parting our lips, want to fuck me in the ass?" "O yes, do you have..." he was saying when I interrupted "Condoms are for girls man, you cant get pregnant so and I'm clean so why worry?" "Ok, I trust you". Good now take that mouth and lick my hole get it nice and wet so you can get in there with that big cock" I got off and onto all fours on the bed, he got behind me and started using some of the cum in his mouth to wet my hole. "Stick your finger in and loosten me up baby" I said. He started one then another then another, for a first timer the kid was amazing. He then said "are you ready" "hell yes I am stick it in there and fuck me like its your last time" 

He pushed his head against my hole, slowly entering making me moan and groan of pain and pleasure at the same time "OMG your big, jesus" "Am I hurting you?" he asked, "just keep going I can take it" I replied. He pushed until he was all the way in letting out moans of pleasure, then he started going in and out fast and faster. "Your girl is missing out on a lot of pleasure baby" I said. "O wow you take it so easy, I understand now what you said about not ever being too big" he replied. He went from making love to fucking me hard and then suddenly "I'm cumming, I'm cumming!" "Dump it in me I wanna feel that cum" I replied.

He orgasmed leaving some more cum in me, as he started pulling out he kissed my back, then my butt and then he turned me onto my back and fell on me and we made out. "That was amazing, OMG, please keep this between us." "What? You think we are done? Nah brah, I wanna put my cock up that sweet ass" I said, "I am not sure I will be able to take it your so big" he said frightened. " Just relax I will go as slow as we need to, you can lower yourself onto me, ok" I said. "just take it easy its my first time having anything inside me" With that i told him to sit up and put his ass on my face, I started licking him hard, pressing my tough to enter his tight ass. He started moaning in pleasure, nearly falling down as I rimmed him. I started inserting one finger, at first he moaned in pain "Relax, you have to relax or its gonna hurt" I said "Ok try again" he said his voice shaking as his cute butt was on my face and his now sweaty body ontop of me.

I went again then another one, until I could fit three in there next to each other making him nice and loose. "You ready?" "Yeah just be gentle ok?" he said. I then turned him over until he was sitting on me, his hole just milimeters from my cock, I started grinding him until he reached back and took my dick and pointed it straight as his pink virgin hole. He got up slightly and started lowering himself down. My cocked pressed hard just parting his hole he gave a shout, I quickly pushed my hand over his mouth "Shhh the neighbours will hear you" I said "Sorry its so big, OMG" he moaned as he kept pressing down about half way down he started going up and down slowly until i put my hands on his hips and forced him all the way down in one quick move, he moaned and then he started riding me like a professional bull rider. 

OMG his ass was so tight I had to hold back not to just burst all over him, he went up and down until he got tired and I pulled him next to me, spooning him as I took my dick and put it back in and started fucking his cute ass hard. "I am cumming" I shouted "Dont pull out leave it in" he said, and barely finishing his sentence I came inside of him and I kept my dick inside of him until we fell asleep, cum dripping out as it started getting softer releasing the seal on his hole.

We lay there spooning asleep until I woke up the next morning with him gently pushing back into me until my dick was hard and I reach around felt up and down his body placing my hand around his month cock, my ass still aching from the night before as he turned around and we kissed "Shall we go take a shower" he said. We got up and hand hot shower sex and continued having sex all over the house for a few days until his sister called saying its safe to come back, allowing him much needed experiment time, and allowing me a new fuck buddy for life.

let me know if I should have a followup story.
