Single mom I throat fucked after I fixed her car

Years ago a woman I went to school with posted on Facebook that her car broke down and she needed someone to fix it but she couldn't afford it that close to Christmas. I messaged her and told her I'd be happy to help so she could have a nice Christmas for her kids and to bring it by my shop. She dropped it off, and I fixed it. Now, I've always been kind of turned on by this girl in high school even though she was kind of trashy. Her mom was a stripper, who I actually saw naked at the club when I was 18 and I received a lap dance from. Anyway, she picked her car up and asked what she owed me. I told her nothing, and to have a nice Christmas with her kids. She said she felt guilty and had to give me something. I laughed and said we'll, you could always blow me like I wanted you to in high school. I laughed and she said "really? I never knew that. Why didn't you say something" and I said I just didn't think she was like that back then. To which she replied "I would have taken every last drop. Lucky for you, I have a few more years of experience now" as she walked over to me and undid my belt, I could feel my cock start to swell. By the time she got it out of my pants, all 8 inches was out and ready to be swallowed. She opened her mouth wide, as I looked down and she put the entire 8" down her throat all the way to the base. She sucked me right there on the floor of the garage, down on her dirty knees. I sat her on the front seat of her car as I fucked her face, I reached down and rubbed her pussy from outside of her yoga pants, I could feel the wetness. I pulled her yoga pants off, and rubbed her swollen clit, I pulled out of her mouth and slid raw into her tight pink pussy, while continuing to rub her clit. She sprayed cum all over my pelvis, causing it to splash onto her seat of her car. I continued fucking her until she had another orgasm. Finally, pulling out and going back into her mouth so she could taste herself on my cock. I pulled out, and jacked a load onto her face, then back into her mouth for her to swallow the rest. After I came, she looked up at me with my cum on her face and said "thank you for everything"
I told her next time she needs her car fixed to bring it by, and she'll know what to do.
