Wife’s encounter

THIS IS ONE OF MY FANTASIES: My wife told me that after a work function last week she was bullied into giving a guy from work a ride home. She had mentioned how he complimented here and suggested that they kiss and so on, throughout all the journey. She told me that she could not wait to get him out of the car. But I could not shake the feeling about how much I fantasized that she did in fact do something with this guy.
My wife is 5’4 , 140 pounds. Big boobs and a nice ass. In the fantasy I can see her offering this guy, 6’ athletic, scruffy facial hair, a ride home. They had been flirting all day at the work function, and even though my wife had a glass or two of wine, she was fine to drive but felt relaxed. She offered him a ride home because his ride left, but what happened was that he wanted my wife to take him home so
He could try and make a play for her. That day my wife was wearing her black pants and a thin black lacy shirt where if you look close enough you can see her bra, which was her favorite black bra. They drove home and talked about the day, and he started to tell her that she is gorgeous and that he would like to kiss her. My wife laughs it off but enjoys the flirtatious talking. He’s getting turned on because my wife is not shutting Him down. He adjusts himself in the seat to show or present is hard buldge in his jeans. My wife takes a peak and he catches her eye. She is embarrassed but he tells her that there’s nothing wrong with looking. He confess to staring at her ass all day. My wife laughs but the energy in the car has completely changed. He suggests they pull off and get a drink from the gas station. My wife agrees and they pull off. He spots a quiet dark area to park. He tells her to pull over and she says why? But he doesn’t answer her. They pull over and it’s a small parking lot covered by trees and out of sight. My wife plays a little dumb and asks him why are they parked off to the side. He turns to her and puts his hand on her knee. She doesn’t move it but plays hard to get. He asks to kiss her. Again she plays dumb and asks why. He just leans in and kisses her. It’s cold and limp at first but within a few seconds my wife embraces the kiss. They make out for a minute or two l. My wife inches closer and closer to him. Her hand on his leg to balance herself. He manages to unbutton her short with one hand which stops her from kissing him for a second. He stares at her tits and she smiles. My wife takes her shirt off as he takes a hold of her tits. She leans back as he kisses them and sucks on her nipples. This really turns her on. They kiss again and he makes my wife undo his pants and pull his cock out. It’s bigger than mine by a few inches. My wife was never a big cock sucker but this cock made her want to go down and for a liking time. She sucked his cock hard, taking it all in her mouth. They eventually moved to the back seat where he pulled my wife’s pants and panties off. She got on all fours waiting for him to shove his cock into her. They started to fuck, slow and gentle at first, with the guy soon speeding up and drilling her deep and hard. My wife could not get enough. She encouraged him to go harder. She told him to grab her tits. He held onto them and squeezed them which drove her wild. He came first with my wife coming shortly after. They both got dressed and my wife drove him home just smiling at each other and themselves.
