The third exclusive release from the elegant, sensitive, and sexy music college student Rei Kuroshima is "Interchanging Body Fluids, Intense Sex," where she has sex in a classy hotel while feeling the eroticism of an adult. She has an elegant appearance, but she is actually... very lewd. She and the man entangle their bodies, repeatedly kissing each other until they are both hot, licking each other's hot private parts, and continuing to have sex even after they have climaxed. This is Rei Kuroshima's first time showing us her "adult sexiness," "adult kissing," and "adult intercourse." It's very erotic.
