Finding Out My Friend Has A Huge Dick

One night after we hit some bars me and some friends were hanging out back at my house.  As the night went on, eventually everyone had left except for my friend Mark who, didn't have a car and was crashing on my sofa for the night, lucky for him.  Me and my gf (hot latina, nice body, great tits, about 5'6") retired to my bedroom (she gets really really slutty when she's been drinking.)   We had barely gotteb into it and I as I was fucking her she tells me she wants a dick in her mouth.  (Now we both already knew that Mark is really hung because he dated a mutual friend who told us ALL about "it".) So I send my friend a text to see if he is still awake.

We go back to fucking and fooling around and I see he replied with, "Yeah whats up?".  I put on a pair of boxers and went out the living room and told him that Stephanie (my gf) wanted a threesome.  We agreed on no gay stuff and he came back and sat on the bed next to my naked gf.  She starts kissing him and removing his clothes starting with his shirt.  She pulls his jeans and underwear down and this massively hard cock springs out.  It was so hot watching her stare at it with hungry eyes and then wrapping her hands around it and putting in her mouth.   

I watched her take care of him for a while, moving her hair to the other side so I can see her lips try to get as much of his cock as she can, before I get behind her and start fucking her doggy style.  I'm fucking her and picking up the pace.  Between her muffled moans I can hear my gf telling me not to stop because she was about to cum but I couldn't hold it.  Watching my friend fuck her face, watching her lips slurp up every inch of him she can take was just too much.  I grabbed her cheeks and with hard deep thrust I unloaded in her pussy.  

After I pulled out she is ready to switch positions and says her jaw is getting tired and now she wants him to make her cum.  My friend asked for a condom, I had one magnum sized left and she helped him put it on and then got on all fours facing me.  I'm making out with her and he's behind her rubbing her clit with his huge cock pressed against her lips trying to push it in.  She reaches back with one hand and helps him get the head in and she immediately lets out a gasp.  "go slow" she told him.  I don't know if he was all the way in or not, but her eyes were starting to roll to the back of her head as I watched his hips thrust behind her.   She's moaning and gasping so much we can't make out and her heads is resting on my shoulder as he starts to pound away.   After a bit of this she tell him she wants to fuck missionary.  She turns around and lays on her back with her head resting in my lap and spread her legs for him.  As he climbed on top of her I watched her guide his cock to her pussy, and then I watched it disappear inside her.  He picked up the rhythm and she was screaming as she started cumming.  He said he was getting close and she wrapped her legs around his waist and her arms around his neck.  They started making out again as pounded the hell out her hard and fast until he is moaning and grunting and starts to cum.  He pulled out and she makes a comment about how much he came and too bad it had to be in condom.  I saw it and it was a pretty impressive load.  

Mark and I fucked a few more girls after this but this time was the most memorable and hottest.
