After work blowjob from a co worker

So today, a slutty older co worker needed a ride home from work. I know she is a slut because she likes to drink and was talking openly about all the guys she has fucked over the years.

She is 44 im 31 she has a boyfriend she lives with, so on the way home (half hour ride) we talk about all kinds of stuff...she starts putting her hair in a ponytail, then tells me "i really appreciate you taking me home" while placing her hand on my cock through my pants. She slowly rubbed it before removing her hand and looking down, impressed with how hard i got so fast. So i pulled over on the side of the road while she sucked my cock for 20 minutes, until my final swell dumped loads of hot cum down her throat, while some dribbled down her lips and down my cock, settling on my pelvis i said "you missed some" and she licked me clean. I filled her belly full of cum and continued down the road to her house. When she got out she said now you know where i live if i ever need a ride again. I looked at her and said "next time i'm filling that pussy up" as she got out and kissed her boyfriend with some of my cum on her lips i couldnt help but chuckle.
