I don't think his girlfriend likes how much fun my friend has with a cock in her ass.

I meet one of my best friends to go buy a couple of gifts for his girlfriend. without realizing it, he lost the ticket and when the security guard asked us at the exit, we both ended up in a big mess. as much as we tell him over and over again that we haven't stolen anything, the security guard doesn't pay any attention to us. in exchange for letting us go free and not telling our parents, he offers us to give him a good blowjob. i get excited right away because i like a good cock in my mouth, the best when my friend gets excited too and starts sucking.
