I did so, and she looked down at my raging hard-on jerking up at her."It will be easier to take the sample if I kneel down in front of you," she said.... Then to my further amazement, she knelt down in the bath so that her face was virtually level with my dick and balls, and started stroking it. I could almost feel her breath on my piss-slit, it was so close to her lips. God, I felt like sticking it in her mouth there and then, but controlled myself!Her right hand wrapped my dick firmly as she. I thought that it would be easy for me and also for my students because I’m a really kind teacher. So, the first day of school came, I met my advisory class, one of the sections in 2nd year. I introduced myself: “My name is bla bla bla bla, I’m going to be your science teacher for this school year....” so on and so forth. Of course, like I said, I’m kind, and also funny because I want my students to be comfortable with me (specially my advisory class). I’m not trying to be kind, it’s really. So to hear her ask for it during sex, I mean, even if he didn't do it, I was just fucking blown away. Another reason I know I'm not a REAL man for her.She put in the request again, more convincingly. "Daddy, cum on, lick my tight asshole." He must have been moving that way anyway, because a second later she yelped, "Oh YEAH Daddy!" I heard her deep, throaty moaning, I could picture her small fanny up high and her face down, with a man's tongue licking and probing her butthole. "Yessss. "I don't know, Master, I haven't even told my husband yet." That shook me but I hoped it didn't show.Get this Earl, she's married, AND the kid's teacher, and the poor sap husband doesn't even KNOW yet she's a black kid's slut and she's gonna come home with a black power tattoo. Anyway, the big nigger grins even wider, and says "it don't make no difference, she gone black for good and they both know it."He winks and says to me, 'don't worry, I help her make up her mind.' I nod, sure I can use.
