The pool day I never planned for [F]/m, BBC

My husband travels for work all the time and I used to hate it, but now I can’t wait for him to walk out the door.. we’ve been married for three years and I never imagined myself cheating on him. I’d only been with him up to marriage. That changed last summer(story is all below) and a few months ago I told him we either get to sleep with other people or I was leaving him..

How it all started:
My husband and I decided to go to our apartment complex’s pool. He stopped to use the pool bathroom, so I went to find us two chairs. As I bent over to set our stuff down, I felt a hand run from the center of my lower back up my side onto my shoulder blade. Expecting it to be my husband, I playfully pushed my hips back and gave my ass a shake side to side, as I did this though, I quickly realized by the height and massive bulge pressing up against my ass that it was not my husband. I jumped forward and spun around to see a fit, tall, and handsome black man. I went into a full blown panic and explained that I thought he was someone else and that I was so sorry. I still remember exactly what he said because it was so smooth “my names not someone else, it’s Alex. No need to be sorry gorgeous. I’m about to leave and my stuff is under the chair, so I was just going to grab it before you sat down, but maybe we take your stuff too and you can finish showing me what that ass does”. Quickly I blurted out “I’m waiting on my husband”.. He nodded, grabbed his stuff and was on his way.
