Turned into a BB sub btm

My names Jake, 5'8 150 blond hair blue eyes gotee, trim but not cut and this story is about how my sisters boyfriend Tim (23) 6'1 185 sandy blond hair hazel eyes a light beard and enough muscle you knew we could fuck shit up but not to the point of busting out his clothes turned me into the BB btm slut I am today. 

My sister and her boyfriend were watching our uncles house while he was on vacation. They threw a massive party that I showed up a bit late for only to find her passed out on the couch and him with a few buddies still drinking and blasting music. 

I walk in and start packing a bong before my jackets even off. Tim's buddies come up start introducing themselves and pouring shots. A few shots and a bong later we're all just chatting,  playing pool while my sisters boyfriend keeps giving me these weird looks. 2am rolls around, the buddies head out. Tim shouts across the basement he's heading to the hot tub and wants to keep the now party of 2 going. 

So I pack a bowl while he does a line of coke, grab some drinks and head out. We decided boxer briefs were the swimwear of choice as nether of us wanted to look for shorts. We're in there about 15 min drinking smoking feeling all sorts of good. Out of the blue he blurts out "ever think about being with a guy"? My heart dropped, I hadn't come out to anyone at this point, I wasn't even accepting the fact I was gay to myself yet; and now 4 feet away is this sexy stud asking me this. 

Thanks pot and alcohol cuz as my heart was sinking I hear myself blurt out "yeah, I've thought about" I don't know who was more shocked him that I had or me for openly admitting it. Things went silent, I quickly light a cigarette just to be doing something and not be awkward. About 2 minutes of silence ensued when out of nowhere he stands up with his boxer briefs gone; he went from being 4 feet away to being a foot an half away with a flacid 6 inch dick at face level. 

I'm all sorts out of sorts on what the hell is happening right now. "Since you thought about it, here's your chance to act on it" the silence had been broken but all I could do was look up at him and back at his dick. I was stammering for words but couldn't speak. He grabs his dick with his left hand and starts to slowly stroke it just staring down at me. "Ok, so I wasn't asking, I'm telling you start working on this dick" I open my mouth to speak when he stops forward points his dick at my mouth and with his right hand starts to pull me by my head to meet his. 

There I was with my sisters boyfriends dick sitting in my mouth not sure what to do. Tim starts to twist his fingers in my hair getting a good grip and slowly moving my head back and forth on his dick. I can feel it growing in my mouth, each time it goes back in its harder and poking deeper in my throat. He steps back to sit on the ledge and is pulling me with him not releasing his grip. By now my mind is racing a mile a minute do I keep doing this, what am I even doing he's doing everything I should pull off and stop his. 

He let's go of his grip of my head and each hand takes a nipple and starts pinching it slightly, this starts a surg of energy through my body and my mouth starts bobbing on his dick taking over since his hands had something new to play with. His dick finally stopped growing with it being in my mouth and not seeing it I would have to guess that 6 inches turned into at least 8.5. This continues for about 30 min his hands going back and forth from my nipples to head. "That's it your doing great" he mumbles "I've got lessons for you to learn". 

All of a sudden his hands look together behind my head and he is pulling me down, his rock hard cock is getting stuffed down my throat. I start gagging and choking trying to pull off for air but he won't let me; I'm starting to feel faint when he releases my head end I pull off trying to get in as much air as I can,  "you're gonna have to learn to breath with a cock down your throat cuz that's were it's gonna be the rest of the night". I just look at him stoned and dumbfounded but I want more so I dive back on his dick sucking it harder trying to learn to breath and deep throat at the same time. After a few minutes he stands up pulls me off his dick tells me to lick his balls, he's jerking while I'm working his balls 1 then the other. 

He tells me to look up at him while I service his nuts as I do a glob of spit comes splashing down on my face. "Once this nut busts, your all mine you will call me Sir and be my bitch". His whole demeanor changed it was no longer 2 guys fucking around I could hear in his new tone he ment what he said and I wasn't going to have a choice. 

Another glob of spit hits my face, his hands once again lock behind my head and his cock is rammed down my throat. He's holding me there then starts fucking my face making me gag choke cover his dick in my throat slime. He's getting rougher and I'm getting weaker but to my surprise my own dick is rock hard I'm hornier than I've ever been and I'm enjoying him have his way with me. 

I'm snapped back into reality by his slamming thrusts to hear "YOU ARE NOW MY BITCH" I feel his dick erupt in my throat 2 big blasts he rips it from my throat and shoots off another 3 rounds on my face and in my mouth. When he finally stops cumming he wipes his dick across my face spreading his seed. Opens up my mouth and says "ok bitch clean my dick" and really for the first time I get a taste of cum and want more. 

This is just the beginning.........
