Injecting aphrodisiacs into the vagina until the wife with large breasts spasms. (This appears to be a reference to a specific sexual act, possibly related to a pornographic or sexually explicit act.)

Sanxi originally wanted to marry a man 10 years younger than her, but he almost never had sex with her. So she went to consult a specialist, who tricked her into drinking a natural hormone, but she didn't know it was an aphrodisiac. In the end, she was forced into arousal until her penis became erect before penetration! She was immersed in endless orgasms and had sex with the aphrodisiac to the point of ecstasy!
