Day with a close friend. Totally unexpected

My close guy friend came over the other day and nagged about his gf being plain vanilla in bed and was not willing to go down on her knees and deepthroat him. Being the good friend that I am, I teased him asking if he wanted his cO*k sucked I can help. He laughed knowing that was teasing him but I thought I'd make him nervous and got down on my knees straight away. He froze and stared at me not really knowing what to do. I proceeded to unzip his trousers and waited for him to stop me. He didn't So I took that as my queue to keep going until his cock was fully exposed for me to play with hahaha. I slowly started to lick the tip, he smiled nervously and was immediately hard. I told him that its a shame his gf doesn't know how to appreciate his co*k with her mouth and then proceeded to take inches in until the tip of his c0*k began to hit the back of my throat. He sunk into the chair and moaned until I finally received his warm load down my throat I swallowed it whole. Sat next to him and said that we should try one more time someday then he kissed me very hard and said of course.
