``It's my first and last time...'' My last night with my beloved sister who has decided to work overseas... - ``It's the last time, so let's sleep together'' and we were alone on the narrow bed! - Every time my sister turns over, her breasts and butt hit and I get an erection! - Then he said, ``You won't be able to sleep like this. This is your first and last time,'' and he started doing it to you with his hands and mouth. - But when I said selfishly, ``I want to do more,'' over and over again, she hugged me with a gentle smile and said, ``Let's do more,'' and in the end, she even let me cum inside her!
