my bestie told me she never gave blowjobs to her husband, so now I suck him off every week

so she told me that she never gives her husband, call him Chris, blowjobs. She said it's been 4 o 5 years since the last one. She said he told her it's his bar none his favorite thing about sex, but she doesn't really enjoy it and added that she likes the control aspect of not giving him what he wants.

Three things came into my mind almost immediately. 1. I thought that was pretty fucked up that she would deny him what he craves most just to be controlling. 2. Chris was pretty handsome. 3. I'm a total blowjob slut.

About a month after Sarah made her confession, we were all hanging out late one night and drinking at a mutual friends house in the backyard. Sarah left early to relieve their babysitter and Chris stayed for awhile. When Chris went into the house for more beer, I made an excuse to go inside too. I cornered Chris in the kitchen and without a word started rubbing his crotch. He got hard instantly. I pulled him to a guest room just down the hall and made quick work of my task. I dropped to my knees, pulled out his cock, and gave this guy the most mind bending blowjob I could muster. He came in less than 2 minutes. I swallowed his cum and just smiled at him and walked out.

He texted me the following day and after a short back and forth we set up another meetup. This time he was going to the grocery store for a few things around 9pm. I met him in the parking lot, blew him in his car and then left. This is essentially what our relationship has turned into. We never fuck, we never kiss, he never touches me in anyway. I just suck his dick a couple times each week. I always meet him either somewhere that's on his way home from work or when he's out on an errand to eliminate the possibility of us getting caught.

I don't need anything reciprocity from him. I get enough dick from other guys that I don't need his, and honestly just doing this with him turns me on enough that I explode almost instantly when I masturbate once I'm home.
