We recruited two college couples who are friends on the internet! We told them that there was a plan in exchange for a large prize, and invited them to the studio to live a life of abstinence for one month! We had them exchange lovers and challenge each other to the "NTR Hard Sex Battle"! Kokoro and excitement mixed in the perverted appearance of their lovers' deep throating, swallowing, drinking urine, and creampies reflected on the monitor, and a big battle of cuckolding and cuckolding broke out! If that's what you're up to... the excitement and pleasure of the sexually-driven college students, both male and female, will not stop!
