Hi you can watch threesome or cuckold Porn with her and try fingring deeply ,kissing,And licking Her pussy without fucking continues try and most important your use 69 session daily .she will enjoy it and talk with you anybody else.
The first logical question is why didn't she like it ? Was he not a skilled lover and yes being a skilled lover is very important. Did she not like his looks? His body?
Was he just a jerk who only wanted to get himself off and not her?
You have to give all the info from HER on why she didn't like it....
