I've been having some trouble with my human anatomy coursework, and who better to tutor me than my muscular stepdad? He's a total hunk with a bodybuilder physique and a massive cock to match. After a little bit of studying, things started to heat up. We moved from the anatomy book to practical lessons, and before I knew it, his big dick was inside me. The sensation was overwhelming, and I could feel my orgasm building up. But it wasn't just about the pleasure for me, I was also turned on by the fact that I was getting fucked by my stepdad. The thought of him being my stepbrother or father in law only added to the excitement. As he filled me with his cum, I knew this was a lesson I wouldn't soon forget.
