I have come home from a long day of running errands. I had no idea you would be there. My son had invited you over to play. He left the door unlocked earlier and would be home in a little bit. You were just waiting until he got home, and didn't know what came over you but got the urge to start jerking off. You wanted to cum so bad. You had been going at this for a little bit but not having much success. It wasn't working as you had hoped and you are having a hard time cumming. It's kind of an ackward moment for me like "OMG! I just walked in on my sons best friend masturbating". You apologize for masturbating like this, you had no idea I would be home now. You ask if it's ok to just try to finish really quick before my son gets home. It's ok, of course it's ok ... I guess boys your age are starting to discover things like this. But you're having so much trouble. Maybe I can help? I know you like big tits, so I'll strip down for you. Maybe that will help you achieve orgasm. I know you like looking at my huge tits all the time, and i love to tease so strip down in front of you. I rub an tease you with my naked body an squish my tits together tightly and this should help unload all that hot cum in your balls. Seeing my huge tits like that. So big and pressed together, hearing me giggling a little. Oh yes that's it !!! Oh wow ! I think your balls are about to burst !!! Oh god, look at all that hot cum shooting out !!! Good boy ... I think that helped a whole lot. Now quick lets get you cleaned up and your pants back on before my son gets home and you guys can hang out. (custom for Mike)
