The summer heat is in full swing as the summer cram school is coming to an end. By the time the long supplementary lessons are over, Ms. Sakisakahara's blouse is translucent, and beads of sweat like pearls are trickling down her chest. It's only natural to feel a surge of lust towards the voluptuous female teacher with her glistening body, clinging hair, and increasing luster. A summer memory. It's no doubt the heat's fault that each of their desires exploded, leading them down the forbidden path of sexual intercourse. Entwined in sweat and bodily fluids, the two sought each other out intensely, time and time again, driven by instinct.
