After Cardio Fuck! The best way to do sports!

I started doing sport more regularly again a few weeks ago and have discovered home workouts for myself. I can do them whenever it suits me and, above all, I'm undisturbed and don't have to be gawped at in the gym. At least that's what I thought until today. After being out and about all day, I felt the urge to do some sport in the evening and decided to do a short but intense cardio workout before going for a shower and relaxing in bed. I put on my short leggings and off I went. I was so engrossed in my workout that I didn't even notice my stepbrother opening the door and watching me do my squats. I wonder how long he must have been standing there enjoying the view of my ass? After all, he made no secret of what he was after so I decided to go on the offensive and tell him that he would definitely like it even more under my trousers. My decision not to wear briefs when I changed heated up the mood all the more and a short time later I was already kneeling on the floor, looking at myself in the mirror and just waiting greedily for his cock and for him to get really horny with me at the end of training hihihi
