Ok, just a few days ago my gf was laying down on her stomach reading her book, and she told me to leave her alone cause i was being stupid or something. So i started to get up, but realized she was barefoot, and she had just finished playing soceer, so she still had the little white fuzzy things from her socks on her feet. I got up like i was leaving, and then i jumped on her calves and scribbled away at her feet. She immidiately went in sane, and tried to pull her feet away, but i had one hand holding them in place. She screamed and laughed so hard that i thought she was faking, but i looked back and her face was red, and she was pounding her bed with her fists. I kept tickling, until her sister ran in and saw. Her sister is just a few years younger, and quite a looker too. She tackled me off and pinned me down, wiggling her fingers inside my shirt. And i blew up with laughter, and before i could recover my gf was on me in an instant. They flipped me on my back, and her sister sat on my back attacking my ribs and my sides, and my gf, ran over and peeled on my socks and grabbed and used two hands to scribble all over my feet. I tried as hard as i could to break free but it was too much, and i coudn't take it anymore. She kept saying stuff like " awww, whats the matter sweetie? are your little footsies ticklish? That's too bad!" and her sister was just like" cootchie cootchie coo!" and both of them were just talking like it was no big deal, like " so what are you going to do tonight, once he is dead? i'm going to go to the movies" and they were just having a 20 minute conversation. When they finished i was drenched in sweat and i couldn't laugh anymore. They both got up and kissed my cheeks and laughed and said, remeber you mess with one of us, you mess with both of us! It was so much fun..haha.
