My sister's friends come over to our house to celebrate her birthday. On the other hand, I haven't had a single friend come over to see me since I was in elementary school! That's just too sad... I planned to mix an aphrodisiac into my house out of spite. But I was honestly surprised by the aphrodisiac's lewd effect, which exceeded my expectations! And even my sister wanted me! I'm doing it a lot, but... is it okay?
