Last year I went round my friends house, I got drunk and couldn't drive back home so I decided to spend the night.. I know this is bad but I had a crush on his sister.. anyways, I got drunk with him in his basement and he sent me up to the guest room. Being drunk I decided to pretend to act like I didn't know I was actually walking in his sisters bedroom, I got into her bed and started cuddling with her... I was soooo happy she let me, we started kissing and she ended up giving me the BEST head I have ever had. The next morning when I woke up, I thought FUCK what did I just do, she was still in bed besides me. I turned over to talk to her and no no no no no no no.... it was his fucking Grandma!!!
