My stepsister sucks my cock for the first time while I am blindfolded

After so many little steps, new things and experimentations, it would have been nice to do something more with Shane... now it was time to give him a blowjob!

After blindfolding him, she would start sucking his cock and at that point, secretly, I would arrive...
