My buddy let me cum in his wife

We were friends for years - the three of us. She was a bit of a flirt - took advantage of her good looks (28, dirty blonde, small breast but a great butt!) got away with a lot of stuff!
I'd flirted with her as much as I thought I could get away with, with her husband, my best friend watching! Nothing serious - some hip bumping, semi-sexy compliments on her bathing suit - her short-shorts, low-cut tops, etc. But spread over like 3 years I never thought it would come to anything.
Turns out this couple had been doing sexy talk and fantasizing about her having another guy between her legs - for quite some time. She admitted to me that, me being over at their apt so often, I was often the star of her fantasy. I'm no Brad Pitt - but I don't do so bad with the ladies.
I'm not a story teller of any consequence - but, well, so here goes.
A Friday night a few weeks ago. We're drinking - husband and I - she's working her way through a bottle of white wine sitting with us on the floor in those little yellow short-shorts again! The damn things are short - but the real problem with them is they are not tight around her thighs. They're 'walking shorts' or some damn thing. Anyway - at least when she's around me - it is never a well kept secret to see what color panties she's wearing. She sits all wrong!, or all right!, on the carpet when we're playing cards, or a board game. That night it was Monopoly. I was losing ...but winning ....the way she was sitting across form me. Knees up, feet spread. pale flowered crotch of her bikini panties on full display over there!
The girl has great legs and a tight perky butt!
She knows I'm looking into her shorts. Her husband sees me, too.
He gives her another glass of wine and the talk gets very sexy! We are telling her how sexy she is - and how we see guys checking her out all the time. She's eating this up....then she does this thing.
She spread her legs in front of herself, and says, "but, don't you guys think my thighs are too fat?!"....as she strokes her inner legs...giving me a great cunt shot into her shorts. She's got a little camel toe going...!
That got everything started towards their bed!
We argue with her, she says, "well, my bottom is too skinny for men to enjoy!"
"Honey he's never seen your bare bottom. Show him what you mean."
"You guys are just trying to get into my pants!"
"Yes we are - we chime in!"
Off comes her shorts, dragging her bikini panties half way down her butt. She tugs them haphazardly up, one handed, giving herself one mostly bare cheek!
Then she's concerned about the appeal of her small boobs.
A show is requested for research purposes!
The girl is standing, swaying a bit - wearing just her bikini panties. She drops into my lap and asks me if I think she's attractive.
I say oh hell yes! - She rewards me with a nice kiss. Then another. Very wet.
She is laying full on top of me, and my hand is in her panties as we make out. Her husband is filming with his cell phone!!!~! So - I get the idea it's OK for my hand to be in her panties and my tongue in her mouth....etc.!
She's a terrific kisser, as I knew she'd be! She's finding my hard-on in my Levis...and someone is pushing her panties down. Might have been me! Pretty sure it was not me who pulled my jeans off!
We are still making out like teenagers - except her knees are spreading and she's reached down and is placing the mushroom of my dick into her very wet pussy!
She drops on me like 110lbs of girl...and I am in her to my balls!
Hubby is still filming - moving around us like a horny Italian movie director! Getting the best shots of butts and slits and anuses and balls, etc.!
This girl is a little athlete! The wine, horniness and pent-up fantasies are....well, there is a little sheen of sweat on her temples and she is working her little butt off!
I'm laying there like a happy clown - as this little blonde is merrily fucking me like a .....no words.
Finally I'm building to a big climax, and I'm not good at putting them off! - I let her know it's near - she doesn't seem to hear me. I look over and tell her husband, my buddy - "I'm going to cum in your wife! ???!"
He just says, "she's on the Pill, go for it you idiot!"
I don't know if girls really can feel a guy squirting inside them - but she knew something was up as I started spirting in her body. Probably my growling and grunting ...or the way I was trying to rip her ass cheeks off...as I came!
She started bucking against me, and bit my shoulder, squealed a little and her legs began to shake......most satisfactorily for the man who was buried up in her sweet sweet pussy! Her sweet abandoned orgasm atop me....was sexy and so cute!
She finally rolled off of me. Used the rest room....and came out wearing nothing but one of her husband's T-shirts. Baring her bottom and her blonde crotch.....now that we'd been intimate she apparently felt no need to cover up.
I loved it!
I don't know if this will happen again. Hard to tell from this story - but she really is not a tramp. I've known her for years. Just a curiosity scratched, like an itch...I suspect.
She asked - while we were still drunk.
I answered, shaking my head...., "Honey, you are one sexy sweet piece of tail!"
She smiled.
