Best friend's step-dad fucks me, blackmail

You are my best friend's step-dad and I invite you over to help me fix my squeaky bed! I see you looking at me and admit I have wanted your cock. I tease you with my mouth before letting you slide inside me, you're concerned about getting me pregnant when I tell you to cum inside me but I assure you I am on birth control! However, the joke is on you, I secretly took pictures of your cock in my mouth while you were distracted! You really should be more careful next time you wouldn't want these pictures to get in the wrong step-son's hands!
