My husband asked me to go to the store to pick up something for dinner so I got in my car with my 19 year old son while he stayed at home with our 22 year old daughter.
In an alleyway near the shops, I was in the back seat of my car with my son's rock hard cock deep in my pussy. As I faced him kissing passionately, the car filled up with moaning and grunting and slapping noises.
???: "fuck mom, this is so hot, I needed to give your present early"
Melissa: "fuck James, you so bad for fucking your mother before mother's day (the 11th of May one), but I love the early present."
James: "well mom, you started it remember, just stop talking and let me fuck you."
He was right though it was my fault how we ended up like this, it was a year ago on mother' day and I have a good relationship with my husband, he was my highschool sweetheart Jessy, now 48 same age as me, he is the father of Milly my 22 year old daughter who is a business owner and my son James 19.
James: Happy Mother's day mom.
I was confused as Mother's day is on the 11th of May as we were America's living in the UK. He gave me a card and a hug and kiss on the cheek.
Melissa: Honey that's sweet of but it's not Mother's day, that is the 11th of May.
James: Correct if we still lived in the USA but we live in the UK now and their Mother's day is on the 15th of March which is today.
My husband and daughter faced each other and I was shocked as we looked online and he was right, my husband panicked and so did my daughter, my son smiled as I thanked him probably.
Milly: No fair, how did you know but we didn't.
Jessy: Yes son, how did you know?
They looked at him and so did I as we waited to hear how he knew.
James: well there were the signs in the shop, we thought it was weird and didn't ask anyone, we only moved here a couple of weeks ago and a guy from college told me the difference.
Again he was right, we did notice the Mother's day stuff in stores and we did ask why, that was our fault and now my son is the only person to get me something and I loved him for it, not like how I love him now.
Jessy: Damn I wish I didn't make plans already, I would have treated you to dinner hon.
Melissa: I understand hon, don't worry you have to make it up to me.
Jessy: I will, I'll make sure of that but tonight I need to see the boss of my work sorry again.
Melissa: I know hon, don't fear I don't mind having a quiet night.
Jessy kissed me and went back to watching tv, James went to his room to play video games and Missy was talking to her friends on the phone, just back to a normal Sunday.
Around 4:30pm My husband left for his meeting with his boss, he kissed me before he left, at 5pm my daughter came down saying she was going to see some friends, she hugged me before she left, at 5:30pm my son came down.
James: hi mom, everyone left all ready, then would you like to go out for dinner I don't want you to cook for us two only.
That was a tempting offer that I took.
Melissa: You know what, I would love to go out tonight and with my baby boy, I'll get ready and we will go.
James: ok mom, I'll get ready as well, I'll meet you back down here.
I got to my room and looked through my wardrobe and ended up picking out a nice dress, nothing to fancy as it was warm outside, I decided to wear stockings with the dress as I didn't fancy my legs getting cold at night, I stripped out of my casual clothes and I pulled out my black stocking and garter belt and noticed that the bra and panties I was wearing would not go well with them.
Melissa: Well I get to chance underwear too, hmm maybe my lace ones, no but then again he won't see it, fuck it I'm wearing the lace ones.
Oh how wrong I was about that but that's later, I put on the garter belt first then my stockings, followed by my lace panties and the lace bra, stepped into the dress pulled it up and zipped it up the side, I look amazing, did some light make up and did my hair up, put on wedge shoes, I didn't feel like wearing heels as I went downstairs to so my son looking so handsome.
James: Wow mom, you look amazing, ready to go out.
I was flattered by his amazement, I gave him a little twirl.
Melissa: Why thank you, you look handsome James
He smiled and looked away blushing, which I thought was cute.
Melissa: well shall we go my handsome boy, I'm not getting any younger.
I giggled as I opened the front door and grabbed my bag and keys.
James: Well thanks mom, and you look good for your age, I think you look younger then most mothers here.
I blushed from his complement as he grabbed his wallet and walked out the door and I closed it and locked it as we went to my car.
We drove to a restaurant that was open, not too far away, we entered the restaurant.
Server: welcome to Tony's Italian restaurant, table for two
Melissa: Yes please that would be fine.
Server: Well you are lucky, we have an open table, I'm sure you and your boyfriend are happy about that.
Boyfriend! She thought my son was my boyfriend. I wanted to correct her but James shocked me.
James: yes my girlfriend and I are celebrating mother's day as she found out she is going to be a mother.
He played along, the cheeky boy but I was flattered that someone thought I could be my own son's girlfriend.
