Please bear with me - this was my first story attempt.
***************
It all started when we were drunk one night and started talking about our past romances. My wife started telling me about her fuck buddy that she used to see before we were dating. I could see her cheeks actually flushing when she talked about him. My first mistake was asking if he was bigger than me - I officially started down the road to becoming a cuckold. I'm not small by any means, but the way she described his cock as though it was magical. As she started telling me about him, I couldn't help but getting hard. She looked down and laughed as she stroked my cock, asking if I liked the idea of her getting fucked by a bigger cock. I didn't answer, so she kept teasing me and asking if thinking about her fucking her ex's huge cock turned me on. She teased me until I couldn't contain myself and blurted out that I wanted to watch her get stretched out by his thick cock. She had this sexy laugh as she made me cum.
Her story woke something up in me - I couldn't stop thinking about her and ex. It was driving me crazy, but I was too nervous to bring up it up again and pretended like nothing happened. Nothing happened that is, until my birthday. She kept hinting that she had a sexy surprise for me, but wouldn't tell me anything. She just told me to meet her at this fancy restaurant downtown. I showed up for our reservation and there she was - wearing this sexy black, tight dress that showed of her cleavage. I lost my breath when I walked in looking at her and couldn't help but appreciate her beauty. As I sat down she told me not to drink too much because she wasn't wearing any panties didn't want me to have whiskey dick - then she spread her legs and showed the sexy view of her freshly waxed pussy - so sexy!
After dinner we caught a cab and headed home. She told me to undress and go into the bedroom while she got my surprise ready. I was lying on the bed when she walked in wearing this sexy red lingerie that showcased her rock hard body. She walked in with a giggle holding some rope and said she needed to tie me up so that I didn't ruined the surprise. She started teasing my cock while she tied me up - no firm strokes, only slow teasing caresses. It was driving me crazy, but she knew her knots and I couldn't move. Finally, she sat on top of me and reach into the drawer and pulled out a super realistic dildo. It was amazing, super thick and a solid two inches longer than me. She just grinned and said I get to watch, and then she started sucking on the huge dildo right in front of me. I could feel how wet she was on top of me and she just grinned when she saw how hard it was making me.
I started to strain at my ropes to get free and she said that I should sit back and enjoy the show as she moved into doggy on top of my face. I'll never forget how sexy it looked when she held the thick dildo against her lips - gasping as it spread her pussy lips - and then slid it in all the way to the base of the dildo. She asked if I liked watching her get stretched out and I almost came instantly my cock was twitching so hard. She started to fuck herself faster with the dildo and I leaned up and started to lick her clit while the dildo kept sliding in and out, stretching her lips apart. Her pussy was dripping into my mouth as she leaned down and started to suck my cock while getting fucked. She started to fuck herself harder with the dildo now - I could feel her clenching down as she neared an orgasm just sucking my cock sloppily. The view was amazing! As soon as she started to shudder with in an intense orgasm I started to cum hard. Afterwards she asked if I enjoyed watching her get fucked and - with no hesitation this time - I said YES.
From then on I couldn't stop fantasizing about making her my hotwife. We kept roleplaying with the dildo, but I still couldn't stop thinking about her ex. We had amazing sex for the next few months - occasionally roleplaying - but it started getting to the point that she started fucking the dildo more and more (it was two inches longer than me). I knew at this point I wouldn't be satisfied until she made me her cuckold, but I was still too nervous to instigate. That was up until her best friends birthday.
We all got together for her friends birthday and went to a fancy restaurant downtown. All the girls were dressed up for going out, but she was a whole other level. High heels and a mesh dress, she looked incredible - everyone in the restaurant was staring at her cleavage. She had this mischievous grin about her all evening that should have told me she had plans for how the night would end. After dinner, she suggested that we all go to a bar and as soon as we walked in it was evident what she was planning - because there at the bar was her ex just smirking at me.
