I can't stop feeling horny and immediately pierce my girlfriend from behind! ! ...I thought it was my sister! ? My younger sister, whose estrous switch was turned on by the shock of the immediate sex, forcibly squeezed my newly ejaculated cock, and when it was full, she inserted it raw herself, and we entered the second round of incest! ! ?
*The setting is important for incest stories. I like settings that are either unintentional or unavoidable, so I hope there will be more in this series. There's nothing funny about mistaking her for her sister.
