Every morning, I commute for one hour on packed trains. Surrounded by middle-aged men in smelly carriages, these mornings were unbearable—until everything changed one day. In the crowd, I accidentally pressed against my rarely-talked-to classmate “Perfume-san.” The train’s sway made me touch her incredibly soft butt, causing an obvious erection. Expecting social suicide, her response shocked me: “You can cum inside me…!!?” Huh?? From then on, daily creampies began—both on crowded trains and after disembarking.
