After being constantly mocked by my three sisters, one day I decided to play a naughty prank on them as they slept defenselessly. As I nervously played with their nipples and pussies, they seemed to be secretly excited and pretended to be half asleep, locking their legs to stop me from escaping, so I ended up getting violated instead. What's more, they didn't let me cum after just one time, and instead sucked my incestuous dick over and over again.
