Input: Text: well a little background, i'm a 16 year old with a craving for lady yummy. well i whack my sack about 4 times a day. yeah, i know that's alot. 
anyway, i was watching television and saw this victorious secret commercial and my willy wanted to get a little silly so i got up and went to my room to do the deed. my internet was down so i couldn't watch my porn videos so i decided to improvise. i took a photo of my sister and her friends at a pool in their bikinis. i thought it was pretty hot, so i unzip my pants and go to work. here's where i fucked up. i was watching tv with my sister at the time and she was leaving to go to a fair with her friends soon, and plus i forgot to lock the door as i'm whacking it. i was pretty into it by meow and  took the blanket off and later there bare ass and everything showing. while in whacking it my sister barges in and asks if i took one of her shirts. ( my parents confuse our laundry often.) she sees everything and runs.  i jizz because of the surprise all over the picture and it just gets everywhere. she hopefully never saw the picture and meow she's in her room with her door locked. fuck my life.
