How she got him to come to our bed

Like nay guys I've always got turned-on at the thought of watching my wife with another man.
My wife was 26 at the time - sexy little dirty blonde with teacup teats and THE cutest tight little up-turned ass. I loved walking a distance behind her in public - her butt in those short-shorts were a real eye magnet for males of all ages!
She loved being looked at. Nothing rude like going without panties - but a lot of males got a peek at her bikini-panty crotch, and nip slips in pools or summer blouses!
So - she'd flirted with my best bud so many times - danced with him when they were drunk in our living room....and each got a little handsy! He put his hand on her butt and squeezed - so, she did the same!
Loved getting ready for bed and then spending a couple hours with us just wearing a T-shirt and bikini panties....which were frequently on display as she moved around, bent over, and sat or lay on the carpet in front of us.
So this night we three got really drunk on hard stuff, a gift from his dad - which we never drank - so it really snuck up on us!
My wife sat sat in my lap and frenched me while I put my hand up her shirt and played with her teats. The my buddy said , "hey, not fair!...can't I have a little kiss, too?"
So she spread her legs, rolled backward soff my lap - I stroked her cunt area, and her T went up to her neck, exposing her teats. She crawled over and climbed seductively up on his lap....and took his head and put the deepest kiss on him!...his hands went right up her shirt...and he did something which made her squeal a little in his mouth. Pinched her nipples, I imagined.
So - everybody is super turned on.....and she agreed to strip poker! She demanded we get down to two items, like she was wearing. We quickly followed her instructions before she changed her mind!
Bingo!~ she lost the first hand, stood in front of us, hooked her thumbs in her panty sides and slowly pulled them down!....while smiling at us.
She KNEW that was a surprise! No T shirt - panties first!
She's standing there with her curly dark triangle on full display. Now she's straightening her curls and patting them into place while looking down and avoiding our stares.
Sooooo. in 1/2 an hour she took me upstairs to our bedroom. Up there she asked me if Mark could join us. I said, if she's OK with it, I guess I am too - our threesome is finally going to happen! but I said he's pretty shy. He might not be ready to do this... She had tucked in drunk Mark on our big couch downstairs.
She went down and about 15 mins she came leading him by the hand into our bedroom.
We 3 slowly fucked, sucked, and necked until just at dawn! She was on the pill - so no worries. Nothing weird...no anal - but she got her butt licked and so did Mark. A first for him!
He learned that she liked her nipples bitten, and that when she was ready to cum the man must pound her hard and FAST! She got pounded a few times! :-)
After Mark left in the morning, she was a little swollen and had pink around her mouth from all the times her mouth was sucked,....
I asked her how she had convinced shy Mark to join us upstairs.
She said, "I pulled his underwear down, cupped his balls and took him all the way to his pubes in my mouth.....and held him in me there while I worked my tongue under his Shraft and slowly milked his balls with my hand. Right when I could tell he was ready to shoot in my mouth, I pulled my face off his crotch....and told him "there's more of me for you if you'll come upstairs"
He did.
Watching his balls tucked between my young wife's ass cheeks as he buried himself in her ...while she locked her ankles behind his back - pulling him deeper!....was a weird sensation. Made my dick hard, my balls ache, and a little sick feeling in my stomach.....
Funny thing - after watching her suck him, him eat her, etc....seeing them go at each others mouths....was what made me the most jealous!
