Known in the office for her outstanding performance and large, beautiful breasts, department chief Ako Kimura grumbled about an upcoming business trip: "I don't want to go..." Her companion on the trip was her problematic subordinate, 'Higashi'—a shy, perverted underachiever who had long leered at Ako's massive chest every day. On the night of the trip, after a dinner with clients, a mistake by Higashi led to them being assigned the same hotel room. Drunk and exhausted, Ako fell asleep, leaving herself defenseless. Higashi, unable to resist, began groping her huge L-cup breasts. Ako woke in shock and tried to resist, but her body grew increasingly sensitive under his relentless, sticky breast torture. "Stop! Don't touch me! Not there... nnng... ahhhh, I'm cumming!!" she cried, yet surrendered to the pleasure. Higashi thrust wildly into his premature pussy, muttering, "I've always wanted to do this..." as he drove her toward climax. "Higashi! Stop... ahh! It feels so good! Aah! I'm cumming, cumming, I'm gonna cum!!!" Ako screamed, orgasm after orgasm wracking her body. The elegant, beautiful boss was devoured all night long by her lewd, shy, and insatiable junior, sinking helplessly into a slick, obsessive torment that refused to let her go.
