"Excuse me for barging in! Can I stay over tonight?" My sister suddenly showed up at my house, insisting on staying the night. Reluctantly, I agreed and we went shopping together or asked her to stay home while I went to work. As night fell, seeing my sister sleeping peacefully, I realized she had grown into a full-fledged adult beauty without me noticing... I shouldn't be thinking such lewd thoughts! The more I think about it, the harder my dick gets, ready to explode...
