Because we want to see a girl go crazy with "sperm itself"... 1. the uncles drink an aphrodisiac → 2. the semen is ejaculated into the mucous membrane with all the aphrodisiac ingredients concentrated in the testicles → 3. Sora goes crazy. Please enjoy the beautiful girl who grins every time she gets ejaculated on, and the spectacular play with the nonstop injection of the hypoallergenic semen.
