Roleplay: i'm stepsis & start by looking at your phone and your photos on it. i tell you to come over here and explain that while you were in the shower your phone alarm was going off, so i silenced it and decided to browse through your photos (while explaining, i am grinning and kind of giggling at times). i say that i saw a couple photos that you may have forgotten to delete...photos showing a certain part of the male anatomy and a ruler. showing specifically 4.3 inches......... i smirk because i can tell you know what i'm talking about, and that's when i say, "Is this really your penis?!" i react like you said "yes" and laugh about how i can't believe i now know what my step's little penis looks like. i continue to tease/make fun of you in a giggling, bratty way (the vibe/tone is that i enjoy teasing/making fun of you, and i think it's so funny that i now know you have a below-average/small penis).
