Tickle Time!

"I still get to be tied up?" You ask hopefully.

She chuckles. "Sure baby, just with one slight alteration."

Shifting around to between your legs she begins untying the shoelace that connected your big toes to your ball sack. As she loosens the loop around your balls you let out soft sigh of relief. She laughs quietly and leans in to kiss your freed scrotum. "That feel better?"

"Mmmmm." You consider it. "Both were good."

She smiles. "Ohhh fuck baby, once we have a place of our own..." She kisses your balls again. "We're gonna have fun you and me."

You giggle.

Fiona grins playfully. "Oh, does that tickle?" Using just the tips of her fingers she begins to titillate the hairs of your scrotum.

"He he he. Yes." You squirm and your balls tighten.

Sitting back on her feet she teases and tussles the curly pubes while barely touching the skin itself. You let out little spurts of laughter and gasps of air. Your balls tighten and draw up at her excruciatingly light touch. The more gentle the tickle the more you wished she would just GRAB you and squeeze. Yet this was delightful in itself.

"He he he he."

She cocks a curious eyebrow. "Hmmm, remember when you were a kid and I would hold you down. I'd sit on you and I'd..." She gracefully moves her hand up toward your foot, her fingers wiggling in a still familiar motion that you hadn't seen since you were twelve. Your eyes widen.

"Oh no!"

It was "tickle time"! Something you and Elsie used to pretend to dread, though actually look forward to, back in the old days.

"He he he, oh yes!" With a sudden dart of her hand her fingers were now tickling the soles of your feet!!! "Still ticklish here?" She asks impishly as her fingers go to work.

"Ha ha ha ha ha ha! Stop! Ha ha ha ha ha! Mercy!" You strain and wriggle in your rope cocoon but there wasn't a hope in hell you could get out.

She holds up her other hand with a frisky flash of her eyes. "Oh Jesse! Both feet at once!"

"OH NO! Ha ha ha ha ha!"

Another swift movement and now your other foot was being subjected to Fiona's merciless tickling! You twist and rotate your ankles to try to alleviate the sensation but Fiona easily moves with you.

"HA HA HA HA HA HA HA!" Your laughter fills the room. "MERCY!"

Fiona cannot help but chuckling along. "You know the safe word."

"No I won't! Ha ha ha! Stop...please! Ha ha ha ha ha ha!" You try to turn over but your sister stops you. "HA HA HA HA HA HA!"

Fiona is relentless. Her face if full of mirth and it is wonderful. You hold out as long as you could.

Eventually however, when you could barely breathe from your laughter, you cry out. "Snake! Oh god...snake!"

She stops and watches you catch your breath. "God you are adorable Jesse." She beams. "You were then. You are now."

You give her your prettiest smile.

She hisses and you see her jaw clench as she turns her head, as if she couldn't stand looking at you for the sexiness of it all. "Fuck you're hot baby! You have no fucking idea what you do to me. You've got me hard and wet all at once baby. Fuck!"

Your smile widens. Those words, that honest desire, they felt so damn good. God you wanted her bad. You wanted her to just hold you down and pound your brains out! You wanted to suck her cock and make her cum. You pray hard that Fiona would be able to be restored soon. "Thank you." You coo bashfully.

She lets out a long breath and gathers her control. "But...you said the safe word. I guess we're all done now."

"WHAT!? No!"

She chuckles once more and pats your ass. "I'm kidding."

You let out a gasp of relief. God, you wanted this night to last forever.

Fiona leans over and kisses the sole of your foot. As she straightens up her eyes are firmly focused on your ass. With her kneeling where she was and you tied like you were she could see EVERYTHING. Your anus clenches and quivers at the knowledge it was being stared at. She licks her lips then says in a calm voice. "Jesse."

"Yes Fiona?"

She kisses your other foot. "When I am back to normal, when I am a goddess again, I'm...I'm big. My cock I mean, it's really big."

You smile. "I know. The biggest. My Mistress is the biggest and the best!"

A brief smile plays at her full lips. "Yes. It's great but...it's not all you might think it is."

"I don't know what you mean."

She sighs. "My boy, not a lot of people cannot handle me. Mom can. Chloe tries her best. But..." She looks you straight in the eyes. Holding up her slender forearm in front of her she makes a fist. "My cock, it's bigger than this Jesse. Do you think you can take that?"

"I'll take it!" You say without even thinking. "I'll do anything for you!"

She looks at you seriously. "Be honest." Always with the honesty with Fiona. So different from your mother's secretive ways.

"I...I don't know." You are **** admit. "I just, I don't know. I've only had you as you are now."

"I am nothing now. And I can last a long time when I'm normal." You could tell she was concerned. "Jesse."

"Yes?"

"May I...fist you tonight?" Your big sister asks with a solemn expression.

There is a hitch in your breath and feel your dick swell even harder against its rope bindings. "Fist...me?"

She nods. "You can say no. But I'd like to fist you Jesse." She motions to the KY behind her on the dresser. "I'll be gentle. We'll go slow." She waits a beat then adds as she looks at her thin wrist. "If you can't take this. You can't...well...then we can't..." She leaves the unpleasant thought hanging in the air. "But it doesn't have to be tonight."

She was right. The idea of her entire hand in your ass was intimidating to say the least! And yet...if you were ever going to make love to your sister once she was restored you would have to take more than that. A lot more than that. You were treading into parts unknown but your mind was wild with love and desire. You had your safe word. Fiona was calm and caring, the monster tucked away for the evening. And FUCK did you want her inside of you!

You say in the meek sissy voice that was quickly becoming oh so natural. "Yes please."

In your sister's hazel eyes you see...pride. "Yes? You sure?"

You nod. "Yes please. I want you to fist me Fiona."

She softly strokes and fondles your fuzzy balls and purrs. "My brave boy."
