During her short summer vacation as a student at a prestigious sports university, Chihiro experienced four firsts. She showed us a different side of her than we've seen before. Her first creampie Tsubasa kiss, with sweat and saliva all mixed together. Her first lesbian experience, in which she had a real orgasm and fell in love with Tsubasa. Her first black man fuck, which made her confused but excited. The world's first double virgin deflowering threesome. Chihiro's summer is intense.
