Step-mommy has all day to play with you, and I am in no rush to let you cum. In fact, I want to see how desperate I can make you, how much you can take before you break and beg. I start with my hands, barely touching you, just the lightest strokes, my fingertips tracing up and down your shaft while I tell you how proud I am of your self control and how much I enjoy watching you squirm. Then I use my mouth, just the tip, swirling my tongue around the head, sucking gently, pulling back every time I feel you getting close, leaving you gasping and throbbing. I suck the dildo to show you exactly what you are missing, my throat taking it deep, my spit coating it, while you watch with aching balls and no relief. I edge you ten times, fifteen times, I lose count as you beg and whimper, your voice cracking, your hands gripping the sheets. Step-mommy denial is the sweetest agony, watching you suffer for my amusement. My big tits bounce as I laugh at your frustration, your desperation only making me want to tease you more. Finally, when I see tears in your eyes, actual tears of frustration and need, I give you permission. You explode harder than you ever have, your cum shooting across your stomach, your body convulsing, and you thank me between gasps. Good boys edge for step-mommy, and you are the best boy of all.
