I only know him for one night and we end up fucking. have i gone crazy?

Just today the boy i hooked up with in a bar a couple of weeks ago presents by surprise. although the thing was just a few kisses and sovereign of the package nothing more. i gave him my phone number and address and i never thought he would show up. i hallucinate when i see him and invite him to come by. he throws himself into my mouth like crazy. fuck with almost a stranger ?. well nothing is a little effort licking his cock and sticking my tongue in his ass.
