It isn't Cheating if it's with Her Mom, Right?

I have been dating Twilight Sparkle for quite some time. Now I'm going to admit, when we first started dating, Princess Celestia wasn't pleased that I was dating her protege and her parents were iffy about me at first. Given that I have been a close friend of Shining Armor, I had his approval and one thing I have learned is that if you have the approval of the big brother, especially when that big brother is the captain of the royal guard then all is good.

One day I was at the supermarket doing some shopping and it was just another trip until I got to the checkout line. Right behind me was Twilight Velvet, Twilight's mom. I'm going to admit, I was always more nervous around her than I was Night Light, Twilight's dad. Yes he wasn't fully sure about me but you know how a young mare's mother is, they are generally very protective.

I turned back and said, "Oh hi Velvet, how's it going?"

Now I made the mistake of taking a very quick glance of her tits, tits that were twice the size of Twilight's. She gave me a glare and sighed, "You know Night Sky, it's not nice to check out your marefriend's mom."

At that moment I was nervous that she might wind up telling Twilight that I was checking her out and I knew that if she did, that would not bode well for me. Not only would I most likely lose Twilight but I could forget about being friends with Shining Armor and definitely be on his bad side. I replied, "I'm sorry, it was just a quick look. It won't happen again."

She continued with the glare, "Well if you don't want me telling Twilight, you'll come with me."

I wasn't sure why she would want me going with her. I was thinking that it was likely going to be her giving me some sort of lecture, something similar to what Twilight gives to those who make her mad or at least annoys her in one way or another. I just hoped that it wasn't anything too bad.

After both of us got done shopping she decided to tell me what her plan was. She began, "Now if you don't want me telling Twilight, you'll do as I say." She pointed towards her vehicle and ordered, "I'll take you home to put your groceries away but then you're coming with me" her glare deepened as she continued "and we're going to have a talk, a very long talk about proper manners."

I had a look of nervousness in my eyes as I replied, "Ok."

After she took me to put my groceries away, I went home with her. During the whole trip to her house I was nervous, very nervous. It was the middle of the day so I was hoping that Night Light was at work but with her wanting to have a very long talk with me, what if it was to keep me there so long I'd have to face his wrath. I know that if he discovered that I stared at his wife's tits, even for a second or two, that hings would not turn out so well.
