Numbuh 4 was clueless about what to do now, Numbuh 3 was underneath him begging for him to do something, but neither one of them knew what. Their bulgy parts felt like they were on fire and his wee-wee was still dripping that strange stuff. Numbuh 4 looked down at his partner in this strange experiment, looking past her cute face, past her bouncy breasts and stopped when he spotted something he had never seen before. They looked like sideways lips, dripping with saliva between Numbuh 3’s legs. Remembering how nice it felt to have her real lips on his wee-wee, Wally tried to see if maybe putting it in there felt nice.

“What are you doing with my kitty?” Numbuh 3 moaned as Numbuh 4 rubbing the tip of his strange stumpy, spitting thing against her kitty. Her body burned with the same desire as Numbuh 4, she needed something but she didn’t know what. As the blunt head of Numbuh 4’s thingy rubbed against her kitty, she found herself trusting up with her hips instinctively, trying to push it in.

“Kitty?” Numbuh 4 said. What a stupid name for a second pair of lips. He groaned as he struggled to get the tip in between the tiny lips. It was harder then he thought it would be, but he wouldn’t stop. “I’m trying to put my wee-wee into it. I think it will feel good for both of us.”

“Wee-wee!” Numbuh 3 giggled and then moaned as Numbuh 4 nearly got it in. What a funny name, she would have called it tasty snake or lumpy, not wee-wee. Focusing away from silly boy names, her intention diverted to the tip of the wee-wee pushing into her kitty. Wally had paused and she didn’t know why.

“Kuki, before I do whatever I’m about to do. I just wanted to say that…I’m glad we took the serum together.” Numbuh 4 honestly said, feeling that what they were about to do had some significance he wasn’t aware of. Numbuh 3 smiled and was about to tell him that she was happy too, but then Numbuh 4 pushed in. the second the head of his cock pushed into her cunt, a hot, throbbing pleasure shot through him. He grabbed Kuki by her rounder hips and threw himself forward, tearing throw her hymen and pushing his whole cock into her.

“THIS IS GREAT!” Numbuh 4 screamed as he felt Numbuh 3’s velvety walls gripping him softly. It felt like his cock was going to melt and his body overfill with pleasure. This was better then desert for dinner, better then free video games, better then anything he had ever felt. Then he looked at Numbuh 3 and all his joy went away when he saw the pain on her face and the hot tears running down her cheeks.

“It hurts,” she whimpered as she felt the pain of tearing her hymen. Kuki had never felt pain like this ever before and she wanted it to end right now. She wanted to beg Wally to pull out, to stop the pain, but then she saw his face and the joy he was experiencing. Like him, seeing the other’s face changed everything for them.

“Oh God, I’m sorry Kuki. I’m so, so sorry!” Numbuh 4 swore as he tried to pull out, but Numbuh 3 grabbed his shoulders before he could remove his cock from inside her. Smiling weakly at him, she simply said, “keep going.”

Unsure about what he should do, Numbuh 4 did as he was told and started pumping into Numbuh 3’s hot, wet pussy. The sensations only got better as Numbuh 3’s pussy contorted around his embed cock. Juices spilled from her cunt as he went faster, holding tightly onto her hips as he slammed into her as fast as he could. Her breasts bounced as he trust into her mindlessly, the pleasure overriding every other thought. As for Numbuh 3 though, she was feeling something too.
