Sonic and manic were at the base with a sleeping Sonia and cyrus with a diagram of sonias body.

"okay, so I analyzed the ray gun. And its not good. But before I explain it, let me clue you guys in. (its about to get scientific in here) the ray alters hormone levels. Mainly testosterone. And when girls have raised testosterone levels… they get horny" sonic and manic went red in the face

"so….. what does it mean? Why are you telling us this?"

"if you hear moaning in her room, don't go in. and if she needs, you should do…. 'favors' for her" sonic jumped out of his seat.

"WHAT THE FUCK IS WRONG WITH YOU? IM NOT HAVING SEX WITH MY FUCKING SISTER! THAT'S ILLEGAL!" sonic flipped. Again.

"hey! Shes gonna be like this for a while, so at least make your selves useful!" he left. Then the fun started. Sonia woke up.

"hmm? Why do I feel nauseous? And horny….." she looked to her brothers. "what h-happened to me?"

" um….. let me try to explain"

25 minutes later…

"so, im gonna be…horny. For how long?"

"cyrus thinks its about a month"

"oh god. I cant even stand it for an hour!"

"um Sonia?"

"yeah manic?"

"cyrus told us to do favors for you" Sonia had an epic nosebleed.

"well, since you mentioned it…" her blush darkened and the phone rang.

"ill get it!" sonic started to go out, but Sonia stopped him.

"manic. Why don't you get that?" Sonia looked calm, and manic was oblivious. He left the room and shut the door.

"sonic, can you," her muzzle was beet red now and she was rubbing her inner thigh, slightly into her skirt "lock that, please?" he locked it and heard squishing behind him. He looked back and saw his sister fingering herself. "ooooohhhhhh sonic. Right" she shoved her finger in and moaned in pleasure. "there!" she opened her eyes and saw him beet red looking at her.

"s-sonia? What are you doing?" she started walking towards him and once she was there she pressed her body against his and slipped his hand under her skirt.

"you know exactly what I was doing, sonikku."

"b-but why were you moaning my-" she kissed him aggressively and looked at him.

"cause I want you." She somehow did an epic move and tore her shirt off and slid her skirt off, revealing her eggplant body. Once that was done she grabbed his arms and kissed him aggressively.

"Sonia!" he pushed her away. "control yourself! Im your brother!"

"which is why its so fucking hot" she went to her closet and bent over, giving him a nice view of her pussy. He felt himself getting hard.

Dead dogs…damn. Sleet and dingo….damn. Robotnik…

"aw damn it!" Sonia turned around and saw her half erect brother standing there cursing himself.

Im gonna have some fun now….. she walked over to him and grabbed his manhood and stroked it slowly. It was killing him.

"oh god harder" was barely a whisper. She layed him down on the bed and took her hand off his now throbbing manhood and put his head in her mouth. His head shot back and he moaned in pleasure.

"want more?" she asked and looked at him. He looked at her an nodded quickly. She started to lick his length and he placed his hand on her head and pushed her head down. She got the message and went lower and rubbed a hand on his balls. She was having fun, and by the looks of it, so was he. She flipped her position so they were in 69. He knew what she wanted so he got to work. He licked her hot wet pussy as she sucked his cock. He probed his tongue in and out of her pussy, making her moan loudly. She went further and started to bob her head up and down.

"im cumming!" he screamed and ejaculated in her mouth. She levitated above his face and opened her mouth. His cum was still inside. She suddenly kissed him and let him taste his seed. He closed his eyes and she laid down. He positioned himself at her entrance and went in slowly. She hissed in pain and started bleeding on his member. He looked at her.

"whats wrong?"

"im a virgin" she said tears running down her face. "keep moving. It feels better" he started to move again, and he moaned loudly.

"oh god this is great!" he said as he increased speed. She was moaning like crazy.

"oooohhhhhh sonic…" she moaned and he picked up speed and hit her womb hard. "OH SONIC HARDER!" she screamed.

"Sonia…im close" sonic stated

"cum in my ass"

"excuse me?"

"CUM IN MY FUCKING ASS!" he pulled out and shoved his cock in her ass and came hard. Once her insides were coated with his seed, he pulled out of her and they both moaned simultaneously. He passed out beside her, and she started thinking.

Only 29 more days left…..she smirked. This is gonna be a fun month….
