Gift and duty (sub oral slave for step Daddy)

Today's a special day. My step-Daddy was so pleased with me, that I get 1 His greatest gift, He licks me out with His dexterous & tireless tongue & mouth. In seven minutes I came 4 times, 3 little & big one. I was so sensitive at the end I must refuse the 5th one. Instead, we change space & I start to please Him with all my knowledge. My boss calls me on phone, but I push him out. No one can diturb me, while I service my stepdad, my only Master. I suck my Masters cock, licking His balls, try to take He likes it wet, so I use as much spit and saliva as I can. He could bath in it. I continue lick His balls, because of that He will spurt much more cum. Simply amazing His hard thick cock, Im almost can come just from wathcing as He jerk it. This time He cum on His stomack, and I can see how much thick, white sperm sprayed out. I think was even better thank I thinked, usually He use my mouth, and He knows I really love to see His spurting cum.
