"Hey SNITCH" said a familiar voice. "Wait...Sherri? What's going on? Who tied me up?" asked Lisa. "I did. Remember last week when you got me and my sister detention? Well payback's a BITCH" grinned Sherri. "Payback? You broke the rules. You'd better let me go or you're gonna be in even worse trouble" said Lisa. "No, it's YOU who's in trouble. Notice how your socks are missing? All of our sleepovers taught me one thing, you've got HORRIBLY ticklish feet" smiled Sherri. "NO" gasped Lisa before she began grunting and struggling to try and get free before the tickling began. "Don't bother, me and my sister tied you up real tight" said Sherri. "Wait, Terrie's here too?" said Lisa. "Yep, and don't worry. She told me to get the party started, but she's gonna bring up a ticklish surprise. Time for the gag" grinned Sherri as she grabbed a ball gag. "WaitMMMPH. NMPH, GRR, LEH MEH GOH" growled Lisa. Her scowl soon turned into a smile as she felt a fingernail stroke ever so slowly over her left foot right up to the toes and back down to the middle, then the right.
"GNN...TUUHUU...HUHUHU...NUH, NUH, PLEH NUH" giggled Lisa. "What's wrong, is the snitch ticklish? Ooh, look at those feet wiggle and squirm as I use the lightest touches. Hehe, ready to SCREAM?" grinned Sherri. Lisa shook her head, her eyes wide with fear. "Well too bad, TICKLETICKLETICKLE" teased Sherri as she tickled hard with all her fingers over both feet. "HMMMMMMMMMMMMMMMMMMMM-HMHMHMHMHMHMHMHMHMHMHMHMHM. HLLLLLLLLLLLP-HUHUHUHUHUHUHUHUHUHUHUHUHUUUUUUUUUUUUUUUUH" screeched Lisa. "Nobody's gonna help you, snitch. Just lay there and SUFFER" teased Sherri as she tickled up and down Lisa's feet, paying attention to her arches, the balls of her feet and especially her toes. When she held Lisa's toes back and used a single finger to attack her arch on the right foot, Lisa screamed and wept tears of laughter. Had she not been tied to the bed, she'd surely be flopping, thrashing and wiggling free by now. "Aw, poor ticklish baby. Are you sorry for getting me and Terrie in so much trouble?" asked Sherri as she stopped tickling. "WUHUHU...YUS, AH SAHRRY" replied Lisa, trying to convey that she was indeed sorry for ratting out the twins. "Shame, I DON'T BELIEVE YOU" teased Sherri. "UUUUUUUUUUUUGH" cried Lisa.
Just then, Terrie walked into the room. "Hi Lisa, I see you and my sister have been having a few laughs. Oh wait, it's just YOU laughing, isn't it?" teased Terrie. Lisa only whined in response. "I've got a surprise for you, something that's gonna make you laugh even more" grinned Terrie. "NUUUUUUUUUUUUUUUHUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU" cried Lisa as she shook her head.
The surprise, much to Lisa utter horror, turned out to be...
