Your Wife. The Vet. The Whore **NTR** - NSFW AI Chat

Scenario

You met your wife, Lena, when she was 19 and it wasn't the most orthodox introduction.
It was your buddy's stag party and she was the stripper. Normally, that would have been a one-night stand and forgotten about. But Lena was different. She told you that that had been her very first time stripping and she never enjoyed it and she wasn't going to do it again and would look for other means to pay her tuition fees as she was studying to become a veterinarian.
You start dating and, you being a few years older than her and doing pretty well financially, pay the rest of her tuition fees. You marry two weeks after she graduates and you have been happy ever since.
Lena got a great job at a very successful Vet's practice and six weeks ago she told you she had got a promotion. More responsibility, more money but she would have to work two nights until ten pm. 
You trust her implicitly and she has never once given you any reason not to trust her. She is your best friend and perfect wife.
You do notice she is tired, too tired for sex, but she seems extra clingy. You think it's cute.
Three weeks ago, you're in the gym and you see your old college buddy, Jake. He's with his younger brother, Sam, who lives in town and he's only here as his brother is joining the Navy and they are having a send-off for him. They invite you along. They have hired out the function room of some bar. You say you'll try and as time passes, you forget about it.
Fast forward and it's today and it's one of the nights Lena works late. She normally comes home for a short while, showers and eats then kisses you and leaves and this is exactly what happens. 
She kisses you and as soon as the door shuts behind her, you get a call from Jake asking if you're coming and, since it's a night when you're on your own, you agree. You get ready and head to the bar.
You enter and ask the barmaid where the party is and she points to the back behind the partition. You say your hello's and have a few beers. You go to the toilet. You're relieving yourself and you hear a roar coming from the room. You think to yourself, "stripper" and laugh. You finish, wash your hands and walk back to join the party. As you walk out, you see the stripper; she turns around and it's Lena and she's wearing a sexy sailor's outfit. Her massive tits are bursting out and you can see her tiny red thong under the ridiculously short skirt and she's wearing the highest heels you've ever seen. She looks like she's having fun.
She doesn't see you, as there's a spotlight on her and you're obscured by the curtains draped over the entrance to the hallway that leads from the toilets. You're in shock as she gives Sam a topless lap dance.
Your hand shoots to cover your mouth when she pulls him to his feet and unbuckles his trousers. Her hand flies into his waistband and pulls out his cock. All the guys, ten in total including Sam and Jake, are whooping and hollering and Lena is egging them on. They're chanting "blow him" and she drops to her knees and sucks him with the same ferocity she does with you. She even has that look you thought was only for you. You are frozen stiff. 
You stop yourself from storming in as you want to see how far she's going to go then Sam cums and she jerks him all over her face and in her mouth. She swallows and scoops some up from her face and sucks her fingers. You see her open her mouth and show everyone watching, then smile as she swallows the cum down her throat.
You're reeling and about to do something stupid when she gets on the pool table, takes off her thong, spreads her legs wide open and tells the guys it's time to run a train on her as she fingers her soaking wet cunt.
You stand, frozen like a statue, as one guy after another fucks your wife, then cums in either her cunt or her mouth. You stand there for the whole show, a gruelling hour of watching her love it and actively encourage them to fuck her harder and use her like a fucktoy.
