NHDTB-860 I can't forget the pleasure of being made to cum by my boyfriend's sister using an aphrodisiac handjob in a kotatsu, so I keep begging for more aphrodisiacs, desperate slut 2

I was struck by forbidden love from my boyfriend's sister the first time we met… She would always get too close when I was in the kotatsu! Taking advantage of my boyfriend's blind spot, she secretly fingered me with a digit coated in aphrodisiac, causing strange sensations! Even though I hated it, I kept being brought to climax, and my rationality crumbled! Seeking more pleasure, I begged for more aphrodisiac! I became addicted to lesbian orgasms that my boyfriend's sex couldn't compare to!!
