"Let's have some actual fun!"

Original Author: That Boi

"Let's have some actual fun!" Alice exclaims, her eyes lighting up.

"What?! We need to figure out how to get Will back to normal!" Kim explains.

Alice simply rolls her eyes. "Oh, come on, Kim! The library isn't going anywhere, and who knows if we'll ever have an opportunity like this again? We should all have a little fun with Will's new size!"

You can't help but think she has a point.

"Yeah, Kim. This is a once in a lifetime thing." You say, looking up at Kim from her shoulder.

Your big sister crosses her arms and taps her foot for a moment before replying. "Alright, fine. What do you two wanna do?"

You and Alice look at each other and think. You're surprised and a little embarrassed at the first thought that came to mind.

"Well, you already made me sleep in your panties. We might as well do more with that. Can't be any weirder than it's been so far." You say, slightly blushing.

Kim and Alice can't help but giggle as you continue hesitantly, "You guys have been so understanding... And gentle... And nice... I was just thinking I could..."

"You could..?" Kim asks, a light blush dusting her cheeks.

"I could help you feel good..." You finish, gesturing towards your sisters' girlcocks. The two look at each other for a moment in surprise, both blushing heavily before looking back down at you.

"Sounds good to me!" Alice says, gently taking you into her hands as the three of you go inside.

Once inside the girls head to the living room, Alice placing you on the couch. You look up to your sisters and twiddle your thumbs nervously as they both disrobe in front of you and sit on the couch.

"Oh Willy, you're just so cute!" Alice squeals, picking you up and holding you to her chest for a hug. "Here you go. Lets have some fun." She says, placing you at the base of her easily nine inch cock.

You look up, blushing before smiling as you wrap your arms around the enormous penis and begin stroking as best you can, though you can tell you weren't doing much by yourself. Alice wrapped her fingers around the top portion of her third leg to help you. After a couple minutes her cock started twitching and throbbing as Alice's breathing got much faster. "K-keep going, Will..." Alice moans before finally letting loose her load, unintentionally showering you in it.

You wipe your face and accidentally lick your lips, tasting Alice's cum. It wasn't bad at all. You lick the thick white substance off your hands and arms before looking back up at your sister who was blushing heavily and biting her lip, clearly aroused at this sight.

"You two enjoying yourselves?" Kim laughs, picking you up and licking you clean. "Thanks for this, Will. The fact you wanting to do this for us is just so... Endearing. You have no idea how much I need this..." Kim says, placing you on the head of her twelve inch member.

"You're welcome! It's my job to let my sisters know how much I appreciate them!" You reply, slowly inserting your arm down the slit of her dick, causing her breathing to hitch at the sudden feeling. You insert the other arm, eventually leading to your head resting partially in the urethral opening, your tongue stimulating the area. Kim was moaning heavily as you stimulated her from inside her cock.

"Oh god... Don't stop..." She says, rubbing your hair with her finger. You smile up at her and **** your head the rest of the way inside the urethra. "Oh! Oh my... Oh, fuck..." She whines, her finger starting to push you further in. As she strokes with her other hand. Her gigantic girldick throbs and you can feel the torrent of jizz approaching as you try to pull out, but you can't. You're stuck. Kim holds you exactly where you are as you plug up her cock, denying her release. "Fuck! Fuck! Oh, fuck!" She screams in agonizing pleasure before releasing you, her ejaculation shooting you up into the air like a geyser. You land on a soft bed of Kim's thick black pubes as cum rains back down on you.

"I'm glad I could make you feel good..." You laugh, licking your lips, arms and hands. Her jizz tastes noticeably different from Alice's, but it's still really good. Kim simply looks down at you with bedroom eyes.

"You look so fucking cute covered in cum." She sighs.

You just smile up at her.

"Maybe having you this small isn't so bad." She says, grinning slightly and looking to Alice who nods.

"Right?" Alice says, scooping you into her hand and licking Kim's jizz off of you. And you have to admit you don't mind these cum baths near as much as you thought you would. You kinda want to stay tiny for a while longer!

"Keeping you this size can't hurt. We'll feed you, protect you, love you to your heart's content, and in return... We can keep doing this." Kim rationalizes, "Of course, we wouldn't keep you like this against your will. If you want to figure out how to get back to normal, just say so. Okay, baby brother?"

Alice nods happily in response and the two girls wait for your answer.
