My Step-stepmom Wants to Help with My Premature Ejaculation Issue

So I have had an issue with cumming fast, forever. I get plenty of girls, because apparently I am at least funny/good looking enough to get through a few dates. Unfortunately, once I finally get to have sex with them, I cum almost immediately. Like two pump chump immediately. I tell my step-stepmom everything, so she knows it's been a big issue for me. Today, she knows that I have my third date (the sex date) with this new girl so she comes to check in on me. Immediately she knows why I am just laying in bed moping, and this time, offers to actually HELP with my issue. At first I am against the idea, but I really will try anything at this point. So she starts slow, a dry handjob, then a lubed one, and then a blowjob. She edges me the entire time, starting, and stopping whenver I am close. After I start to improve there, she steps it up a notch by putting on some really sexy lingerie. She starts going again, working through the stages, until she finally thinks I am pussy ready.
