Thalia - 2:

"Thalia, you've lost the bet - now you gonna pay the price." the son of Jupiter told his sister who was standing across from him as he sat on a soft couch. Remembering their bet, who would come first while fucking each other the last time, Thalia sight and said: "Ok, what's the price?".

The blond-haired demigod smirked and showed her two objects he had held behind his back until now and explained "You will have these two in your pussy and ass the whole day. You are not allowed to remove them, I'll take care of this myself tonight."

The daughter of Zeus looked skeptical and asked her brother what the big deal was and what he would have of it, if she had to keep a small anal plug and a weird egg-shaped sex toy inside of her for the day. Jason smirked before saying "You'll see. Now turn around and bend over!".

Rolling her eyes Thalia, who was still naked from their previous activity, turned around and bend over to present her pussy and ass for her brother. The blond-haired boy slid a finger around her pussy entrance to test her wetness and deemed it sufficient for the 'weird egg-shaped sex toy' as his sister had called it.

Jason pushed the pink toy deep inside her pussy, which elicited her a moan, before tending to the second object. Once again he slid a finger around Thalia's entrance, only this time it was her asshole, which was still covered in a bit of lube from their feel-good time together. As her asshole was slimy enough too, he pushed the silver anal plug into her opening just as he had done it with the other toy - again she moaned out loudly.

What his sister didn't know yet, was that both toys were actual vibrators and he would turn them on and off as he pleased during the day.

As both toys were in place, Jason slapped Thalia's ass and said "Get dressed or we will be late for breakfast!". With these words he stood up and left to freshen up a bit. When he came back, his sister was ready to leave and they made their way towards the mess hall.

***** Short Time Skip - at breakfast *****

In the middle of breakfast Jason deemed it time to turn on the toys embedded inside of Thalia. He hit the button and suddenly Thalia, who set to his left, shrieked in surprise. The campers looked a bit confused but as the daughter of Zeus made no further sound or movement they tended to their food once again. "What the fuck Jason!?" Thalia exclaimed silently while trying to ignore the vibration in her pussy and ass. "What's the matter?" her brother asked innocently but his smirk betrayed his words.

"You didn't tell me these things would vibrate!" she breathed out while balling her hands into fists to hold back her moans. The son of Jupiter grinned at her and told her: "I said you'll see…" and with that he stood up and left as he had already finished his breakfast.

Thalia stood up and bit down on her bottom lip to keep her moans inside as the toys shifted inside of her as she moved. 'Oh gods!' she thought 'How am I supposed to live through this day without anybody noticing something?'.

The daughter of Zeus had to take a detour towards the armory because she was dangerously close to a heavy orgasm but couldn't risk anybody hearing her moan or scream out - she ended up in the woods and came behind a couple of bushes. She was to slow to relieve herself of her underwear which led to a quite sticky situation.

When she finally reached the armory to get a selection of weapons her soaked underwear rubbed against her moistened cunt and clit with every step she took. The girl made her way towards the arena and tried to ignore the pleasant vibrations inside her pussy and ass.

Thalia fought the best she could with a distraction like the one between her legs but it was difficult to do so as her movements caused the toys to wander deeper inside of her and penetrate more sensitive spots. At the end of training the black-haired girl had come two further times while fighting but no one seemed to be suspicious about her as she had concealed her screams of pleasure as battle cries.

As she finished her training the egg inside her pussy and the plug inside her ass stopped vibrating. Thalia looked around and saw Jason with the remote in hand as he gestured her to follow him to grab some lunch.

"You're evil." the daughter of Zeus accused her brother who just grinned and said "A bet is a bet. If you take them out I'll find something for you that will be even more fun." while mentally adding 'for me!'. Thalia groaned and rolled her eyes before she assured him that she knew the rules of their deal.

As the two siblings finished their lunch, Jason told his sister to go and get her bikini because they would spend the afternoon at the beach with their other friends.

The black-haired girl did as she was told and quickly made her way towards her cabin to get her favorite black bikini - as she reached the cabin and closed the door behind herself both toys suddenly started to vibrate full force, causing the demigoddess to scream in surprise.

"Fuck - he is doing this on purpose!" Thalia moaned out while she started to undress. As soon as she was naked, the girl took a glance at her pussy and found it drenched and dripping with her own arousal . 'Not surprising after what happened at breakfast and while training…' the black-haired girl thought and started to put on her bikini. As soon as the fabric touched her pussy it got soaked with her juice and a dark wet spot became visible.

To hide her arousal Thalia slipped back into her shorts and made her way to the beach. She had to stop multiple times to catch her breath to prevent herself from coming and screaming out as both toys, the egg shaped vibrator and the plug still hummed inside of her pussy and asshole.

***** Time Skip - Thalia arriving at the beach *****

When she finally reached the beach, the black-haired demigoddess had come two more times despite all her efforts. Thalia moaned quietly in relieve as the toys stopped vibrating, she looked up and saw that all the others were already there. Jason made his way over to her and grinned as he saw her state. "Maybe you would want to get rid of you shorts and get in the water, you're leaking, dear sister." he said with a smirk plastered on his face. Thalia looked down and had to admit that her brother was right. Her pussy juice had leaked from her slightly sore cunt already two orgasms ago but now it was running down her thighs.

"Fuck!" she said, undressed as fast as possible and quickly got into the water. She used it to wash her arousal off a bit but she knew Jason would turn on the remote controlled toys again soon - and she was right.

Thalia spend the rest of the day at the beach while her brother switched the two devices on and off as he pleased, causing her to come multiple times. Every time she reached her climax the young demigoddess dived under the ocean's surface to choke her moans and screams as much as possible.

***** Time Skip - after sundown *****

Jason and Thalia made their way towards their cabin and Jason glanced towards his sister before saying "You did well today but we are not done!".

The daughter of Zeus looked at her brother and asked him what he meant with saying this. The son of Jupiter chuckled and said "You had this things inside you the whole day. Time to get them out and replace them with a real cock!" before slapping her nicely shaped ass once.
