When I went to Tokyo to take the university entrance exam, I decided to stay in the house where my eldest son and his second son lived. By chance, the two brothers were on a long business trip, and a strange cohabitation began with the two sisters-in-law. Three days until the exam, I studied hard but couldn't escape my brother's G-spot. During that time, I was pushed down by the saying: "Study for the exam, you have to take a break...", until before the exam day, whether I was sleeping or waking up, my beautiful ass had squeezed out all the seeds.
