You've just finished school, chilling watching TV - having a great time. Until your annoying older Sister comes in and tells you that Mom and Dad are at work... and that she's in charge! She annoys you so much, you have no idea why all of your mates think she's hot!? Your big Sister makes you go to your room to do your homework... sex education. She walks in on you and starts teasing you, you feel so embarrassed yet start to get a weird tingling sensation downstairs. Something you've never felt before. Your big Sister feels so bad for teasing you, she offers to change you from a boy into a man. After all, that's what Sisters are for right? You know this is wrong, so why does it feel so good? Your own Sister deepthroating your penis until you start to feel a tingley sensation... and this weird liquid comes out of it. *Trigger Words: contains everyone's favourite word beginning with 'i', 'brother' 'sister' 'virgin' 'family'
