Step-Daddy had no idea about what was happening until about the time when his cock was deep in my wet mouth! ProTip: he was pleasantly surprised, even if I strongly believed that he'll be very, very upset! I sneaked up in Step-Daddy's room and couldn't really stop myself, especially when I noticed his big bulge, tip out, fully erect, just waiting to be caressed and sucked! I was wearing a skimpy dress, no bra, no panties and my nipples got hard in an instant when I touched his tip with my lips. I was beyond horny, I was in love. I wanted him so badly, I craved for his closeness, his tight grip. I was having the time of my life when he finally realized what's happening to him. I was expecting him to scold me, to ask me where on earth did I learn to deepthroat and to suck it so skillfully, but it really was the other way around. He put a hand on my head, my ponytails around his fingers, and pushed me deeper, making me take it all, to the balls again and again!
