Friends mum 100% true story... SeXStoRY

Right first of all this story is 100% the truth i assure you. I wasnt going to post because under rules it said "fantasys" which means made up but anyway.... I was at my friends house having a chat as i havent seen him for a quite a long time, we used to be very close we used to go on holiday together etc. So we was having a pizza and just a chat to see what hes bin upto over the months, then he gets a phonecall from his mum asking him can she pick him up from the pub as shes been out with her friends from work, now because my friend has had a drink he cant and im the only sober one there because i drove to his house. His mum knows me so i offered to pick her up thinking nothing of it of course as i didnt want her to get a taxi with all the weirdo taxi drivers about, then she said yeah. So i drive to where she was at which was a pretty large pub down a country lane, pretty upper class. So i pick her up and on the way back (the lane is about 2 miles long)she asked me could i pull over has she wanted to be sick, which i was totally fine about as i didnt want it getting in the car!. So she got out the car, walked over to the side and squatted down to be sick, this instantly turned me hard but i thought nothing of it and its a good job i had jeans on. Then she was coughing pretty heavy and i shouted over to her "are you ok" she replied "yeah im fine" but she sounded like she was choking abit. so i went over to her and said "are you going to be ok" she said "yeah2, then she said could i help her back to the car, so i helped her up seeing a flash of her knickers on the way. She sat in the car and she just said to me in usual d***k talk "I really appreciate what you have done for ****(friends name) over the last few years, since we was struggling as a f****y you have always been there for him which i massively appreciate and he thinks alot of you as a friend" So the conversation carried on then the next thing she leaned over towards me and tried to kiss me, i was totally shocked and i paused not kissing back to think the situation through. She apologized then when i thought to myself "once in a lifetime chance, you live once", i put my hand up her dress and started to rub her pussy through her knickers she just laid back and started to breathe heavy then she said to me "finger me babe" as to which i stook 2 fingers up her very wet, pretty slack pussy. Then i said to her lets nothave sex in the car lets go into the woods, so we walked through to a pretty dark place where we could see what we was doing but not too light, she started to suck me off for about 10 minutes then i insisted we had sex and got home before it got too long. So she stood up pulled her dress up and revealed this amazing G string, i think my cock gained half an inch from just seeing her in it, i couldnt take it no more then i was about to take the g string off and she said "dont take it off just pull it to the side and slam me" so i my dick in her and started going for it, it felt amazing, never felt nothing like it. It didnt last too long as you can imagine i was so turned on, after i finished firing my spunk in her mouth, she swallowed and i give her some tissue in my car to wipe her pussy with. Best night of my life, just hope no one finds out!
