Ok...I know this is beyond kinky for many, but I totally did not plan this.
In fact, I have never even considered anything like this in my 26 years, it was totally spontaneous.

I am happily married and almost 7 months pregnant.
I am 5'10, and normally weigh around 130-135 for perspective sake.
My Husband is a great man and an excellent provider.
However I am often lonely as he works on an offshore oil platform and is gone for long periods.
Just over 3 months ago my 19 year old Brother moved in with us after he transferred to a college close to where we recently bought a home.

Matt (not his real name) is a very cool guy. He is handsome, smart and very athletic. Much like my husband.
My Brother started advertising in craigslist as an unlicensed masseuse, and gives massages to men and woman for $35.00 for a half hour, and $45.00 for an hour.
He does fairly well, and is a self starter. He's never any trouble and I love having him around for company, security, and conversation.

My Brother has been attending Lamaze classes with me and helping me around the house a lot. We have two dogs, and I am a clean freak, so they get bathed every 10 days or so in our large master shower.
Now that my baby bump is now more then just a bump, My Bro has been washing the dogs. The other day he washed the dogs, and I just assumed he would be wearing trunks, boxers, or something. Matt finished washing Travis, our ridgeback, and called for Pooka, our 1 year old Lab. When I brought him in, Matt was standing there ready to hand off Travis for me to dry.
As I turned the corner, I could see Matt was naked, and he made no attempt to cover up. He has a beautiful body...around 6 feet tall, dark hair like me, his eyes are blue, mine are green.
I'm a terrible judge of weight, but he is an athlete, and is fairy muscular so he looked great. What got my attention though was his simi erect penis. I have seen a fair amount of penises in my life, but Matt's was so thick. I mean.....I know he is my Brother, but a penis is a penis, and Matt's was impressive!

My Husband has a great dick...it's pretty big, but I always wished it was just a little thicker.
So....I made like I did not really notice, or care that Matt was naked. I handed off Pooka, and took Travis and dried him.

While Matt began washing Pooka, I felt a bit flushed, so I went to the kitchen and opened a bottle of wine, and had my allowable single glass of Merlot.
I changed into a leotard that accentuated my full breast, and what I considered to be a still pretty good body for a preggo girl.
I really had no intentions other then I was horny as hell and there was a man in my shower with a great body and hell of a thick penis. I was not attempting to seduce Matt as much as I was attempting to look as attractive as he did. We were both good athlete's, and both very competitive.
Soon Matt called my name again. I walked in with a fresh towel in my hand and grabbed pooka. Instead of leaving though, I sat down and began to dry Pooka.
As I did so, I looked up and Matt stood in the shower looking at me. This time though his dick was fully erect....it stood up with a pronounced upward curve, and t was so damn thick with a very large reddish purple head. OMG....It was so hot.

I kinda starred at it...I mean...I could not help it. Matt looked at me and could not judge what I was thinking and started to apologize, and began to cover it.
I told him it was ok....I mean...I told him I thought it was the nicest penis I had ever seen.
Matt turned so red...so did I. We both started laughing.

Pooka was dry, and I let her run off. So..matt began to wash his hair as we made small talk. His hard dick stayed hard...it might have even gotten a little harder even.

As we talked I was nervously rubbing my neck, that was constantly bothering me due to my weighty preggo tits. Matt asked if my neck was hurting and I said yes...as usual.
He said that hot steam and a good rub would make me feel like new. I said I was not too sure if that was such a great idea, and Matt told me I was being foolish and to just get naked and get in the shower with him. He said..."Its not like were gonna do anything"

I was taking the last few sips out of my rather large glass of wine, and said...ok...what the heck.
I stood up and pulled my leotard to the ground and stepped out of it in one full motion.
My boobs that are normally a perfect 34C were now more like a 36 D.

My only embarrassing aspect was that I usually trim my bush pretty tightly but have let it go a bit so although my black pubes were not out of control, I had a fairly thick pelt of pubic hair.
I walked in clutching my favorite bath towel, and Matt slowly took the towel from me and hung it over the shower glass. We stood there for a sec, just facing each other. His stiff dick pointing straight out at me. I began to laugh, as he had shampoo on the tip of his nose and his hair was sort of pointing up with shampoo in it. He laughed and this broke the ice. He had a bottle of bath gel in his hand. He squeezed some into his hand and told me to turn around.

I did and he began to massage my neck. And OMG...it felt so good. My pain began to subside almost immediately.
As he worked my neck, I commented how good it felt, and that what if our Mother, or my husband walked in....what would they think??
He said it did not matter...he was just making me feel good. He said...I mean, I'm making you feel better"
Just as he said that...that big cock of his poked me in the right but cheek. Neither of us said a word. His cock remained in contact with my ass, and I told him that everything feels so good.
Matt began to sort of gyrate or thrust ever so slightly as he worked my neck. I began to push back (not so slightly) in an obvious sign of approval and continued my moans.
Matt then did something that would alter our relationship forever.
He slid his hands down my sides, reached forward with soapy hands and began to massage my boobs.
It felt so good. Both from a massage point of view...(My boobs were pent up inside a bra that was too small, and from a sexual point of view.
His big fat penis was now firmly pressed against my bubble butt, now sorta on the bibber side, and I all I could think about now was getting my hands on it and sucking it.

I know it was so wrong, but I wanted to fuck my Brother. Or rather, I wanted to see what it would feel like to have that double wide dick inside my vagina!
I moaned, then reached back and gripped my Brothers dick. Oh...Oh...It was so nice. I mean, it was like a perfect penis. I reached back with my other hand and grabbed my Brothers muscular ass. Wow.....I thought to myself......Gee, my Brother is going to make some lucky girl very happy with his perfectly muscular butt and beautifully large thick dick.
He throbbed in my hand. At first I just gripped it as I marveled at how my hand was so small wrapped partially around it.
Matt began to moan as he slid his hand down and began to rub my unusually hairy vagina.
I blushed with embarrassment and told him I usually shave it almost smooth.
Matt told me he thought it was extra sexy...and that he likes a pussy with a little extra hair. That made me feel better...he began to rub my clit and finger me slightly as he thrusted his big dick in and out of my hand.

My husband had been offshore for almost three weeks, and even before he left, this last time, we did not have sex cuz his back is messed up.
I gave him 3 blowjobs while he was home which he loves, but I have not had a real penis inside of me for nearly 2 months.
I was not sure exactly how this was going to go, But I knew something was going to happen. I wont lie, I wanted my Brother to fuck me, and to fuck me good.
I turned to him and faced Matt. He said he thought I was beautiful and the fact that I was pregnant turned him on like crazy.
I kissed my Brother lightly on the lips while stroking his penis. He started to suck on my large nipples as if I was nursing him.
I then sat down on the shower bench and took the head of my Brothers penis into my mouth.
It was so thick. I took my time and slowly tried to get as much into my mouth as possible...my pussy was flowing and aching to be filled.
I began to suck my Brother using mostly my hand and mouth.. Only maybe 3-4 inches fit in.
Soon he asked me if I wanted to "do it" ......I looked at him sort of confused for a sec, and he said, "You know...do you want to fuck"??
I did not say anything, but stood up and turned away from him. I bent slightly and told him to go ahead and stick it in, but to go slow cuz he was bigger then what I am use to.
I felt him guide the tip of his engorged cock to the entrance of my vag. He then stopped, dropped to his knees, and began to lick me and tongue me.
He then slowly began to enter me. It's strange....but I really did not feel as though I was cheating on Michael (my Husband), rather I felt so excited that I was going to screw a man I have known all my life, I loved, and that I trusted.
Matt slowly pushed his dick into me until I felt his rather large sack resting against my vag/bush. He did not move at first. I felt so incredibly full...I MEAN I WAS COMPLETLY STUFFED FULL!
It felt so good. I asked him if something was wrong because he was not moving, and he said he almost ejaculated as he entered me and he wanted to control it.
He then began to withdraw and re-enter as we began to screw.
Matt reached around with soapy hands and massaged my pregnant utters as he thrusted very powerfully in and out. Pumping me as my entire body shook with each thrust.
I reached behind us and was so turned on as I grabbed at his powerful ass as he pumped me. I then reached down between our legs and rubbed his large sack as he moved in and out of me.
I could feel my Brothers balls slapping my swollen vag and inner thighs as he pumped me harder.
Within 30 thrusts or so I began to feel something I have never felt....a vaginal orgasm was building. Don't get me wrong...I have had orgasms for years. Starting when I was 13 or 14 years old. however THIS WAS DIFFERENT!
All of my orgasms to this point have been due to clitoral stimulation. My Brothers thick penis was hitting all the right places, and the amazing upward bend in Matts penis was rubbing me in a place I never new I had.....I began to weaken and shake. Then...OMG...I started to cum like never in my life.
Thank goodness we live on a flag lot and no neighbors to close cuz I screamed like I have never done before. I always thought screamers were full of it.
Well....I was completely full of my Brothers big dick and I was almost paralyzed with pleasure.
As my 30 or 45 second blast of pleasure began to subside, I felt Matt grow even bigger inside of me, and as his balls slapped up against me in a frantic pace. Matt began to grown and he started to slow and spasm as he released inside of me.
When this started I was going to tell Matt not to cum inside me just because.
But now, I wanted to feel my Brother squirt inside me. Normally I cant actually feel a man cum in me.
But this was different. I could not only feel Matts powerful contractions, but I could also feel his semen flood my vag. There was just so much...and as he continued to grown, he continued to flood my swollen Vag with semen.....As his moans subsided, and we slowed, I knew we just completed one of the major taboos.
Strangely, Matt did not really shrink much, but as he pulled out of me, I could see the seminal fluid drain onto the shower floor...it was like watching horses breed(I have seen that at a friends stable) there was so much semen draining from me. He came like a pony.
Matt then turned me to face him and said he was so sorry for cumming inside me. I kissed him lightly on the lips and told him it was okay.
He promised me that he was sure he had no diseases or illnesses, and that if we ever do it again he would pull out.
To be continued...we ended up doing it a lot in the coming days and months.
