Seiya's fourth Shinagawa date with her boyfriend finally comes true! After enjoying French cuisine in Odaiba, they go shopping and head to a hotel. Their lunch features a simple course menu, but they're satisfied with the authentic flavors and attentive service. Soon after heading to the hotel, they dive into sex. In the bathroom, they start sucking each other's cocks, taking turns passionately. Moving to the bed, they stimulate nipples and share endless kisses, chasing intense pleasure. Seiya lies on her back as her boyfriend focuses on her highly sensitive nipples. Then, after preparing her anus, he penetrates her from behind with his rock-hard cock. While groping her breasts and grinding her nipples, Seiya moans loudly, writhing in ecstasy. Switching to missionary anal sex, she revels in the rubbing sensation, exclaiming, "It feels so full!" Her disoriented responses during handheld filming—“Where does it feel good?” “I don’t know!”—are irresistibly hot. This time, Seiya's adorable ahe-face truly stands out. Her boyfriend cums first, blasting a huge load of cum onto her face. Seiya then jerks off her own cock, kissing as she shoots a generous amount of cum. After bathing, they enjoy dinner in Shibuya, return to Shinagawa for more drinks, and head to a third bar. This loving couple's night of heavy drinking and constant kissing continues endlessly—truly an enviable romance!
