Forbidden inclination stepson 18 seduced into sex

My new boyfriend’s son is just 18 and really cute. And you’re not supposed to do that, but inside I always have this forbidden inclination and the urge to play with fire. When the old man is finally out of the house, I sneak into his room! I use all my skills to try to seduce him! You’ll have to see for yourself how I manage it, but in the end he had a big load of cum for me. Could I have seduced you?
