I was caught looking at my stepsister with lustful eyes, so I decided that from now on I wouldn't do anything perverted again. As a condition, I got to insert my dick for just 3 seconds! What luck! My stepsister said, 'You can't be trusted, big brother!' and tried to insert it herself and pull out in 3 seconds, but it hurt too much to pull out! What the hell?! Could it be... vaginal spasms!!! Taking advantage of the situation, my stepbrother said, 'If you can't pull it out, then let's just do it like this laugh' 'Maybe it'll come out easier if it's all slippery with cum laugh' and kept ejaculating inside her continuously! Finally, I managed to pull out my dick, but now my stepsister is excited?! She actually begs, 'I want big brother's dick...'
