GS-362-2 My sister's friend came to play with a miniskirt that looks like pants!

My sister’s friend came to play with a miniskirt that I could see my pants! A friend who waits for his younger sister who is away starts rumbling with bare pants like his own house, and this one involuntarily erects! My sister’s friend who noticed the erection told me to have sex in secret … I couldn’t stand it and made me squid again and again!
