OMG! Horny stepbrother is secretly watching me work out! Now I’m working out with his equipment!

I was in the middle of my workout – but somehow I suddenly had the feeling that I was being watched! When I turned around, my pervy stepbrother was actually standing behind me – with his hand almost on my ass! What the fuck does he think he’s doing? At first he tries to talk his way out of it, saying he just wanted to correct my posture, but I don’t believe a word he says! But then he brazenly unpacks his hard cock! I have to admit, I couldn’t resist any longer! The sight of his hard cock makes me want to do a different kind of workout! On the mat, he first gives it to me deep from behind and then takes me from the front with his big cock! Of course, I can’t miss the proteins after the workout – luckily he has a huge load of them for me!
