While my girlfriend was away, I was restrained and unable to move by my idolized older sister, and she kept bringing me to orgasm. (Yamagishi Aika PRED-477)

I've always secretly admired my girlfriend's older sister, Fenghua. While my girlfriend was away on a trip, I blindfolded and tied Fenghua up. Ah, now I'm free... Overcome with excitement, I relentlessly and violently ejaculated inside the immobile woman. I fully released the pleasure brought on by my lust. From then on, she obeyed my commands and made love to me many times. Her powerful thrusts with her hips brought me to a complete orgasm. Look, look, Fenghua, you still reach climax because of your sister's boyfriend's penis.
