My stepsister asks me to be her personal trainer and I end up fucking her deliciously again and again

My stepsister wants to start exercising and she sees that I practice every day and I have a good physique, so she asked me to go to her house and help her train, I gladly went, because that way I could be close to her, whenever we have been close We are attracted to each other, we like each other and this is an excellent opportunity to see each other up close, to be able to caress her and fuck her, because I know that she wants the same thing for us to fuck again and again, so I'm going to my stepsister's apartment and I'm going to fuck her .
