Big tits, amazing hourglass figure, short hair, and a love for M-men—this is a joint performance by a combo with many common points! Mio Kimishima and Asahi Mizuno are imprisoned to be impregnated by the M-men. They must accumulate excellent sperm in the edge-holding room and have intercourse every day without fail! Even if their testicles dry up, they must keep ejaculating inside! The only way to escape the imprisonment is to get them pregnant! Is a life of constantly having sperm extracted heaven or hell?!
