Sexual lessons

[T_B]

This story is about Jim (you can change any names you want) he's 19 the women he had sex with call him a sex god his mom is 37 she has D cup breasts she met her husband when they was at school and agreed to wait to hang sex until their wedding night jim also have a 18 year old sister

One night Jim over heard his parents fighting they was fighting over sex his dad Steve had heard adout his friends sex life and when they learn that he only does the missionary position with his wife and never even heard of other positions (or ways of sex like titty fuck oral and anal) he tried to do them with his wife Brittany after they tried some of the positions and oral and neither of them being good at them they started to fight (it started right after Brittany gave him a blowjob and unfortunately she used her teeth) both of them blaming the other for their crappy sex life Jim heard his dad was going to sleep on the couch

The next morning Jim noticed that his parents was still upset with each other but his sister Anna didn't the biggest clue was when Steve left with out kissing or saying I love you to Brittany after his sister left Jim decided to help his mom he told her he overheard them fighting and offered to help Brittany said that she can't have him help her and that she was thinking about finding a marriage counselor Jim asked her if she ever heard about of her best friend sex life and she embarrassingly admitted yes

She heard that her friend husband was thinking of a divorce because she couldn't satisfy him and close to cheating so many times but then she surprised him by learning skills from a "Marriage counselor" Jim asked if she told her that and Brittany said no she just assumed Jim then revealed that after Brittany's friend found out about her husband wanting a divorce and Brittany trying to cheer her up Jim who just walked in noticed offered her help what she took and she was satisfying her husband in less than a week

Brittany was shocked to learn that but after a quick call to a friend found out he was telling the truth and agreed to letting Jim help Jim makes her promise to do everything he says he first tells her to strip naked after some resisting she reluctantly did it he tells her to shave her pussy and then have her follow him to her room after looking at her underwear told her to throw them all out and they're going shopping later he then told her of her first lesson a blowjob and to practice she will be using him Brittany asked if there was another way and Jim said they could use Anna's dildo but the best way for her to improve it to use a real dick after some convincing she was giving her son a blowjob him giving her tips

At the store he took her underwear shopping and was having her try on thongs and some sexy bras she was to embarrassed to come out on the changing room so Jim just goes in with her telling her that the underwear looked sexy on her she asked him to leave so she can try on the others but Jim told her that she doesn't come out you might go to stay in so she changed in front of her son near the end she told him to stop humoring her about the underwear as no one would want to see hey in them he took her hand and put it on his dick and told her he was not humoring her and here's the proof you choose if anything happens in the changing room

Back home Jim told Brittany to go to her room for her next lesson and she was horrified when the lesson involved him fucking her your choice how the rest of the lessons go but by the end Brittany was great at sex but Steve was still the same and she could satisfy him but he couldn't satisfy her she asked her friend if it was the same for her she told her that comes close and she actually once a month actually meet up with Jim at a hotel just to get satisfied after that Brittany told Jim that he ruined her as she can't even feel good from having sex with a husband and tells him to take responsibility and satisfy on a daily basis

Optional Jim could have trained Anna as well since her 18th birthday
