A shared taxi home

I said goodnight to all in the club and made my way outside to catch a lift with one of my drinking partners wives, i noticed B standing outside the club waiting for a taxi, we struck up a conversation and had a bit of a laugh, i asked her where hubby was and she replied she was out without him.My mate came out and asked if we were ready to go, i paused for a minute and asked B if she would like to share a cab with me instead as we both live close by.
We got into the cab and set off,its not far so its a shortish journey, i noticed she was sitting very close to me and made it clear she had something in mind.We have no real history, just a kiss at new year, anyway she started to kiss me passionately and made a point of moving her hand over my now semi erect cock.
As i said the journey takes no time at all, so when we got near B's house we both got out, she made more attempts to kiss me and said lets walk away from her house to where there was a group of large trees and bushes on the end of a row of houses.We walked into the bushes along a bit of a clearing along the last house, she pushed me back against the wall of the house and kissed me long and hard again,i was getting more and more aroused, she was wearing tightish white jeans which i managed to undo the button and pull down the zip, pushing my hand inside feeling her slightly hairy pussy, she was already wet, so slipping in a finger was quite easy,she moaned as i pushed a couple of finger into her wet hole and she came almost immediately, she was so turned on as i finger fucked her lovely warm pussy, my cock was straining in my jeans and she could feel this as she undid my button and slid down my zip pulling out my rock hard cock and full balls, i continued to finger her pussy as she started to wank my cock, she just kept cumming and saying how fucking good it was. She then said to me she wanted to go down in me, well the offer just turned me on even more, she then knelt down and took my cock in her eager mouth, she certainly knew how to give a great bj, she sucked on my rock hard cock and i had the perfect view seeing my cock dissapear into her hungry mouth watching her cheeks bulge as my cock went right in, it was to much i knew i couldn't hold on for long, then she stopped sucking and started to wank me, i said i was close to cumming so she lowered her head and took me in her mouth again,as soon as i felt her start to suck my cock again i could no longer hold back and shot a big load into her mouth, she made sure my cock was fully emptied, but spat it out which tbh i found a great turn on watching a woman spit all your thick cum on the floor. She wiped her mouth and kissed me long and hard and said when hubby was next away she wanted me to fuck her hard on her big white bed, which sadly never happened, we said our goodnights and parted into the night.
