MM's new project 'Boyfriend Swap! Blue Sky Strip Tw○ster' is a bold content where friendly couples on a W date, approached on the street, take on the challenge. Although the friends aim to clear the challenge together, the gradually escalating extreme missions and the sight of their friend's girlfriend's divine I-cup breasts and fair, large buttocks bring them to the brink of explosion, making it irresistible. Moreover, the unavoidable erection in the slippery lotion-covered close poses leads to a raw insertion accident with a JD girl!? The sense of guilt increases sensitivity, leading to complicit cheating SEX while watching their beloved partner in front of them! Swapping and creampie, it's truly shocking content. The performances by the four actresses 'Sakura Mahiru', 'Okamoto Riri', 'Ayase Mana', and 'Hazuki Noa' were also outstanding, with Mahiru and Nanao's H scenes leaving a particularly strong impact. The casting of busty actresses was excellent, and the youthful sexiness of miniskirts and white underwear stood out. Although it's a bit disappointing that some parts were edited due to time constraints, the overall content was satisfying. Looking forward to future series.
