Sisters Little Present

I woke up one Saturday morning feeling soo horny my balls were swollen and ready to be drained. I knew that my mum and dad were both at work all day but I didn't know if my sister was.

I laid in bed for a few minutes trying to listen out for her moving around in the room or downstairs, after I while I got bored of the silence and decided to get out of bed and have a look round the house still with my erect cock, I shouted round the house and realised she wasnt in so I randomly decided to have a look in her room.

I walked in to a pile of her pjs from the night before, I had a little route through and found a pair of nice white knickers. As I picked them up a realised that they were stained at the front I was so horny by now my knob was covered in pre cum. I walked over and laid on her bed and placed the knickers on my face and sniffed where my sisters pussy had been.

While I was sniffing I discovered they were still wet so feeling super horny I sucked the crotch and drank my sisters juice. I was ready for blowing so covered my dick with the knickers and shot my full load in them. I was going to throw them away when I had the idea to leave them back in the pile of pjs so she could find them.

I still don't know whether she found them but it turns me on thinking that my sister could of found and reused her cum stained knickers.
