[MF] Marine watches his wife fuck her stepbrother

I’m a US Marine, currently deployed for the reserves. I recently got back with my ex wife in a trial capacity and we’ve been having a pretty good time. Probably too good, not really focused on fixing our relationship and more on the physical.

I have always encouraged her taboo inclinations and made her call me daddy or tell me how she wants her stepdad to fuck her brains out etc. Her family has always been kind of open sexually and make “jokes” about each other all the time.
Her younger brother would constantly talk about her physical features in a super non brotherly way whenever he thought I wasnt listening for years and she always kind of brushed it off.
She eve once or twice joked about how he couldn’t get a girlfriend because he was too big for them. This boy is a skinny little hipster type….

Two weeks before I left for deployment we went to visit her 19 year old brother for the weekend in TN. We decided we were going to all go out to the local 18 and over club and he would be the DD. We had s good time. A fun night with lots of dancing and my wife dressed in an incredibly slutty outfit and boots. I was drinking s lot, but still started to notice her and her brother were getting really touchy feely. This escalated all night to where she was actively grinding on her younger brothers crotch in her tiny hiked up skirt and I could clearly see his fingers in the waistband of her panties more than once.
I ended up blacking out and coming to in the car. I was in the back seat and we were still in the park g lot of the club. I barely woke up and cracked my eyes and I saw them in the front seat. She was over the center console breathing really heavily. Her top was pulled down so her perfect c cups were out and he had his hand wrapped in her hair, just kind of pulling it.

I could see her shoulder working and I heard her whisper “it is so. Fucking. Huge.”

I watched for about 30 minutes as my wife took out one of the biggest white cocks I have ever seen in real life or online, and proceed to try to deep throat it like her life depended on it. Her brother reminded her I was ‘passed out’in the back numerous times and she never stopped. She came twice from him playing with her while she had about a third of his cock in her mouth.

I still haven’t told her I saw anything and she told me yesterday she’s supposed to go stay at his place again this weekend. I’m about 2000 miles away.
