19 year old cousin

It was around winter 2010 and my hot cousin was staying the night with my sister. It was your typical boring night so i went out the back to take out the bins on my way back in i saw my cousin walk into my sisters room and take off her top so i jumped over the small to hide.I was fully expecting her to close the curtains but she didn't. I'd always wanted to see her naked.She took off her bra and then her underwear her tits were bigger then i imagined she put her pants on and got a phonecall so stood toplss talking on the phone. At this im rock hard when she left i went back inside and wanked like mad man its been 8 years and i can still picture that hot teen fucking body
