A scientific experiment: a Japanese man pumped his squeaky wife full of sperm.

Pregnancy is a delicate matter, and if you don't know what you're doing, you're unlikely to successfully impregnate your female. Don't think that to get pregnant you just need to poke the pistil with the stamen and pour your nectar into it. The Japanese do everything scientifically. Before cumming inside his wife, an experienced Japanese man spends almost an hour teasing her hairy pussy with vibrators and making her cum... that's the scientific approach.
