My girlfriend's beautiful and slightly sadistic older sister saw right through my masochistic nature...
"Sister, stop! I'm going to make a sound..."
"This is what you really wanted, isn't it? (laughs)"
A nympho's torture repeated in a situation where I can't make a sound because my girlfriend is right there!
"If you make a sound, she'll find out, right? (laughs)"
Toyed with by authentic masochistic pleasure techniques in a situation where I can't make a sound!!
With her outstanding slim yet busty body and those authentic masochistic pleasure techniques, my reason is completely ignored and my erection won't stop!
"Please! Bully me more!"
The one who trained me into a masochistic man who can't be satisfied without being bullied and toyed with was my girlfriend's older sister...
