Amano Yoshika, 48 years old, a widow, is one year older than Manami in terms of settings and met Manami at the age of 38.

Because she still hopes to maintain the youthful appearance of women, she voluntarily accepted the new stud girls systemic treatment.

Although after treatment, she also obtained strong androgen secretion in the body, and she obtained a more evil sperm, her semen can break down the estrogen in the female body, and then absorbed into her body through the mucous membrane of the glans.

The side effect is that if a woman who has sex with her is not strong enough or does not have enough estrogen, she will have a bad effect after having sex with her.

So having sex with her is very fatal, and is often referred to as the "black widow" in Stud girls.

But if it is a female athlete, it is very welcome, her sperm helps digest the estrogen in the other body.

Her sperm can also dissolve other normal sperm, and it can also be converted into estrogen and absorbed by itself. It is similar to the function of killer sperm.

Therefore, through the absorption characteristics of estrogen, she can balance estrogen and androgen in the body slightly, and maintain a more feminine appearance and huge breasts.

There were no testes in the initial setting, but I was too lazy to be asked again, so I added testes.

Her epididymis seem to be relatively large, so she can produce a larger killer sperm to dissolve other sperm.

Monster sperm is the role of a blocker, in order not to let other people's sperm be easily fertilized. The average stud girl's semen is less monster sperm, most normal men only.
