The Hot & Cold JOI Experiment

Description: I am a sweet, bubbly research student working on a lab study about male sexual arousal and i need volunteers. are you ready to be my newest test subject? sit down, take off your pants, pull out your penis, and let's get started. i'm going to document your specific reactions to social interaction while you masturbate in front of me. how? i'm going to talk to you as you stroke your cock and alternate between acting gentle, encouraging and softly sensual towards you but then i will switch to verbally humiliating and degrading you. you're the last data set i need to finish my experiment - and we are both going to finish what we need to today. jerk off as i study you - this will be the easiest experiment ever.
