Bladder replacement for my best girlfriend...!

My best girlfriend's boyfriend rang my doorbell last night. I opened the door and was only wearing briefs because I was expecting someone else. My girlfriend had been telling me for a long time that he had a really hot cock, so I'd been horny for him for a while. I seized the moment... and lured him into my apartment... then I saw how he looked at me from top to bottom... and already had a mega pipe in his trousers!!!. I took the initiative and took off his trousers... and sucked his cock.
