Things have changed recently, I was in a relationship with a Dom where we had a contract. Then he met someone else and they got married, but now that technically makes him my step-father! I figured our sexual relationship ended when he started that new one, but I was wrong. The relationship just expanded I guess and now he need to remind me who I really am, a submissive pain slut that is meant to serve and obey. I feel awkward at first and try to explain that this is wrong now, but quickly I am put in my place and relax once my collar is put back on. My Dom slaps my face and tits to bring me to attention before having me stand up and bend over for a hard spanking. With no warm up at all, he brings out a few implements and immediately lays a thick leather strap into my big bare butt. I know we have done this before, but it has been so long and so my booty was in for a rude awakening. It starts out with some spacing between hard hits as he still lectures me on our new dynamic. I stay in position like a good girl as the hits keep coming faster. The strap is replaced by a wide leather tawse. This time with more hits coming faster, but he stops to look me in the face as he reminds me that I am meant to be in this position. Being a pain slut and serving him. Back to the hard spanking he goes and soon the dreaded bath brush is brought out. I know this one will hurt the most and he never goes lightly on me. I look at the brush for a moment before it disappears behind me. My bubble butt is turning all kinds of colors as he lays into me, making sure to hit all over. The top, sides, bottom and even thighs get whacked over and over again. To lay in the lesson, he has me count the last dozen while saying "I will obey and serve" after each one. Things have gone back to how they were, me in my place as a submissive, but it'll be very different now (roleplay, taboo role play, step-dad, Dom/sub, BDSM, pain slut, submissive slut, sub training, collar, tit slapping, face slapping, choking, spanking, M/F spanking, strapping, leather strap, leather paddle, leather tawse, wooden paddle, wooden bath brush, red bottom, bent over, naked female, CMNF, clothed male naked female, embarrassed naked female, big tits, big ass, bubble butt, huge booty, round cheeks, thick thighs, 38dd tits, 51in ass, hourglass figure, tall girl, thick, curvy, brunette, brown eyes, light makeup, hair up, hair in clip, Dani Sorrento, spankdani, Universal Spanking, UniversalSpank, stern lecture, dirty talk)
