My serious sister, who has nothing to do with eroticism, discovered my fleshlight! She kept asking me how to use it over and over, so I demanded she become the material for a live demonstration! Then my sister showed me her panties and breasts! Furthermore, when I got carried away and came on her, I found out that my sister had been secretly aroused… Moreover, after learning that using a fleshlight too much can cause vaginal ejaculation disorder, my sister insisted on training for vaginal ejaculation to relieve her sexual frustration for my sake, making her feel intense pleasure over and over. Now she doesn't need the fleshlight anymore...
