I'm writing this to sort of help me process what has happened in the last 24 hours. If someone had told me what happened would happen, I would have never believed it, but it did and I'm rock hard replaying the scenario in my head.

So my birthday recently passed and for my birthday I had bought tickets to a baseball game for me and my gf with 1 extra ticket. The tickets were bought probably 2 months in advance since both our birthdays are within a few days of each other's. Initially the plan was that her stepfather would come with us which wasn't my favorite idea but he's manageable so I didn't mind. Suddenly the day of the game my gf tells me that her mom is going to go to the game with us, this made me pretty excited since that with all the walking and the heat that day her mom would almost definite wear something open toed. My gfs mom(Glenda well call her) has some amazing sexy feet. Probably a size 8 or 9 with a decent size tattoo on her right shin going to her foot, always perfectly pedicured toes with a nice design and color sometimes bedazzled, she was a bit heavyset so I assumed she probably had deep wrinkles. I'd be sneaking peeks at her toes all day and I couldn't think of a better way to spend my birthday than that short of having them in my mouth.
So we go to the game and it was a scorching hot day with not a cloud in the sky. As the 3 of us walked back to the car exhausted from a day of cheering, drinking and sitting like nuggets under a heat lamp my gf told me to open up the back of the car and grab something for her. I was almost positive what she asked for was at home but I looked anyway and continued to look until I felt something wet touch my cheek. It jumped to see my gf's foot right next to my face and in pure shock turned my head in the other direction just to see another bare foot in front of me, it was Glenda's foot. At this point my brain was practically dead and I just stood there staring at her purple and silver toes, I turned and faced my gf and she smiled at me and said "go on it's your birthday, I've caught you staring at her toes more times that I can count, don't be shy now." I turned and faced her mother and she looked me with a sultry look that I had never seen before. She picked her leg and slowly placed her foot right on my chest.
"Now kiss her toes" my gf barked at me.
"And after you kissed every toe you will come over here and lick my feet clean because they are sweaty and filthy."
I kissed all 10 of Glenda's toes as slowly as I could make myself and then got to work licking my gfs feet clean. First, I got all the sweat and dirt off of her sole with long licks from her heel to toes. Then, I sucked each of her toes and tongued them down good making sure to get all the dirt between them. At this point my cock was rock hard and was pretty sure I had precum in my underwear. Once I finished she quickly recoiled her feet away from me.
"Okay now get in the back seat here" she said. I couldn't believe what I was hearing, I hopped into the back seat so quick I almost dinged the car next to us opening the door. She told me to take my pants off and my underwear, I was on autopilot now I was so turned on.
I never saw it coming. Her hand reached and grabbed both of my balls, pulling them down with almost catlike reflexes. I groaned slightly as this was absolutely nowhere near as hard as she would normally squeeze me.
"Now listen to me, next you're gonna clean her feet. But while you clean her feet your balls are gonna be right here with me." She gave my balls a quick squeeze for emphasis. "Then after that we're gonna show her just how much you love it when I squeeze on your balls." So I got to work, it was a dream come true to finally have Glenda's toes in my mouth and to lick her soles. I took my time with her feet even though I was in constant pain the whole time.
Once I was finally done my gf told me to lay down. She said I could finish myself off worshipping her mom's feet but she would keep squeezing my balls as hard as she could until I came. Obviously I agreed without a second thought. So I layed there with Glenda's bare soles on top of my face and my balls in a death grip all while stroking my cock at a furious pace. It must have been about 2 or 3 minutes of silence before I could feel myself getting close to the edge. I repositioned myself to put Glenda's big toes in my mouth and this made my gf start slapping my balls with one hand while holding the squeeze albeit with a looser grip.
When I say it was one of the strongest orgasms I have ever had I feel like I'm making an understatement. I layed there nearly comatose with my Lower half fully exposed and a smile like a fat kid who just finished my 3rd slice of his favorite pie. My gf hopped in the driver seat and drove to her mother's house to drop her off before going to our house. When she parked the car she looked back at me still laying there although I was alert and just kinda basking in all the glory of what had just transpired. "This doesn't get spoken about to anyone ever, and maybe if you don't fuck up until Christmas maybe I can give you another pair of feet for Christmas." She said as she winked her eye at me and got out the car, quickly pressing the button on her keys setting the alarm and running in the house.
