I moved into my aunt's house in Tokyo to attend university open campuses! With her husband away on a business trip, it was just the two of us. Seeing my scrawny physique, my aunt forced me to join her daily training routine! Meeting her for the first time since childhood, I found she had kept herself fit through self-training; she was beautiful despite her age, and her mature sex appeal was incredible! I got a full erection from the temptation of her peeking breasts and jiggling big ass! Then, with whispered dirty talk and touches to my cock, she shook her plump ass and happily performed a semen-vacuuming, pile-driving cowgirl piston! Her insane hip movements made me ejaculate over and over again! A carnivorous instructor beauty vs. my scrawny, introverted self!
