Was I too naive? Perverted man fucks my mouth

I just wanted to buy used tools, but the guy from the ad totally fooled me. When I wanted to look at the tools, this asshole simply pulled out his cock and started jerking off in front of me. At first I found it disgusting, but somehow the sight turned me on. I then simply got down on my knees and started sucking his cock. I fucked him harder and harder in my mouth and then wanted to do a titfuck too. In the hope that I would get my cheap tool, I let him squirt his sperm into my mouth. After he had cum, he didn't give me the tool, but just ran away... what an asshole!!!
