Everyone went with the first option. Before they started, they helped Sonic get up from the floor by lifting his manhood as he stood up. All four of them went outside, heading into the thick woods behind the house so nobody could see them. Once they arrived, they let Sonic drop back down on his knees.

"Okay," Tails began, "Me and Cream will bring the ship here! Stay put and tell me if anything else happens!"

Once Tails got their nod of acknowledgement, he and Cream darted back to the house. Once they reached it, they both climbed aboard, before flying back to Sonic and Sally. While on route, Cream asked Tails if this option would be hazardous to either of them; she was responded with 'not really, as long as we go in and out quickly'.

-------------------------


Sonic stared at his giant penis, with worry and disbelief. He wondered what would happen if things didn't work out, and how his manhood could even get so large in the first place; what if this was permanent?

"Sonic..." The hedgehog looked up to see Sally, who wore a face of reassurance on her. "There's no use thinking about the possible outcome; all we can do is wait and see, but I know everything will be alright." She placed a hand on his shoulder. "Just calm down."

Sonic smiled. Besides Tails, Sally could cheer him up in even the worst situations. "Thanks, Sal."

"We're here!" The two looked to where the voice came from to see Tails' ship landing in front of them. Tails got out of the ship with something in his hand, before running over and giving one to Sally. "That's a transceiver. I will use it to call you when it's time to... you know," Tails instructed, hinting by what he said by aiming his eyes to Sonic's limp rod.

Sally nodded, grinning slyly. Even though she was now pregnant, that wasn't going to stop her from having a bit of fun. "Alright, Tails. Trust me, I know how to get him... steamed up."

"...Ooookay. I better get to it now."

Tails ran back to the ship, climbing back inside before shrinking the vehicle down in size. He flew the ship in front of the entrance to Sonic's manhood, before picking up the transceiver. "This is Tails. Is everything is working order?"

Sally responded. "Uh... yes, Tails. It's working alright."

With nothing left to check for, Tails flew the ship into Sonic's opening, and turned on the headlights, traveling down the long tunnel that seemed to go on for miles. After many twists and turns down the urethra and the vas deferens, the two explorers arrive back in the testicles.

"Whoa..." Tails interjected, dumbfounded. "This place has gotten huge!"

"Will Mr. Sonic be okay, Tails?"

Tails nodded. "He will, just as soon as I prepare this." He referred to the object he just picked up: an orb. "This orb will spread a substance all aover the place, and conception will trigger it to regulate everything in the reproduction system. Don't ask why I made it, though."

Tails tossed the orb from the ship into the rete testis of the testicle, watching it spread its substance around. Now was the time for Sally to do her part. He picked up the transceiver and made the call.

-------------------------


Sonic watched as Sally talked to Tails on the transceiver. The call didn't last very long with only Sally saying 'okay', 'be careful' and 'bye'. Sally then put the transceiver down, before looking at Sonic with a seductive smirk.

"So, Sonic..." She gently laid Sonic down on his back, bringing herself nose to nose with her boyfriend. "Are you hungry?"

Sonic only raised a brow. "Um, didn't we just eat earlier?" Once Sally gave him a deadpanned look after that question, his eyes widened. "Ooooh... In that case, sign me up, princess."

Sally smirked, standing back up before turning herself around so her back was facing him. She put each of her feet beside the left and right of Sonic's head, and looked down at him while giving her rump a shake. She promptly rubbed her fingers on her vagina, making her wet and horny, before lowering her butt onto Sonic's face.

Sonic began licking Sally's opening, already feeling flustered. He considered himself lucky; it's not everyday a princess is willing to sit on you and let you taste them. He felt his giant tool getting hard, and Sally had noticed how tall it was standing: a bit taller than her eye level, throbbing and all. Sally, panting from her treatment, took things a step further by wrapping her arms around the manhood and stroking it up and down.

-------------------------


The substance was beginning to react, and that was the moment Tails knew it was time to get out of here. He flew the ship back the way he came, hoping to escape before Sonic erupted while he and Cream were still inside. He could hear Sonic and Sally outside, surprisingly, and that's when he herd those dreaded words: 'Sally, I'm gonna...'. Tails could see the exit, and sped up the ship to its limit. The walls surrounding him and Cream began to vibrate, and the moaning of the two outside grew louder and louder.

Tails thought he wasn't going to make it, but he was able to escape just before...

"I'M GONNA BLOW!!"

Sonic's penis erupted violently like a volcano, shooting semen straight into the air, but an an arc so it didn't land on them. As he kept on ejaculating, Sally (who also blew her fuse) could feel Sonic's rod getting smaller and smaller, until several seconds later it was back to its normal size. Tails had done it. Sonic was back to normal!

The hedgehog in question was panting. "Huff... huff... I came," he stated like an idiot, earning a little laugh from Sally, who got up from Sonic's face.

Tails landed the ship on the ground, growing back to normal size. "Hey," he said while opening the cockpit, "is Sonic alright?"

Sally nodded. "Yes, and thank goodness too! Thank you so much, Tails!"

"Heh, you're welcome."

Sonic slowly sat up. "Hey, bro. I think you deserve more than just a thank you; I think permission to enter our bodies isn't needed anymore, right, Sal?"

Sally looked back and forth between the two boys, before sighing in defeat. "Well, alright... but promise me you won't cause trouble?"

"Cross my heart," Tails promised, using his fingers to mark his chest with an 'X'.

Sally smiled. "For now I think you should rest after this."

"Yeah, I guess you're right, Aunt Sally. I'll come back and visit sometime, okay?"

Sonic stood up, smiling. "I'll be waiting, buddy!"

"Bye, Mr. Sonic! Bye Miss Sally!"

Sonic and Sally waved goodbye to Cream and Tails, who teleported their ship back to the workshop for a good long relaxation. However, it wasn't going to be as relaxing as Tails thought it would be, not when a certain somebody still wanted to learn more.
