Energon Soup for the Horny Spark

The teenaged girl had always seen herself as a human dating a robot. She had been comfortable showing Bee her naked form. Opening up to show her robot insides was another matter.

"Its too small anyways... we couldn't... bond still..," said Sari with a sudden blush. The redhead had usually been in control of the 'interfacing' side of their relationship. She now showed an obvious weak spot.

"Can I still see it?" Bee asked with softened optics, "I mean... If you don't want to thats fine...."

"Y-you can see it. Ah, after all... I've seen yours," Sari blushed even brighter. She touched the organic like flesh in the middle of her collarbone. Above her small breasts a chamber opened. The previously unseen doors slide backward to expose her spark. Sari's small white spark rested in the casing. It was smaller than a human heart but pulsed like it was beating. Bumblebee stared in his usual dumbfounded awe expression. Sari became nervous and reached to close up the chamber.

"No wait," Bumblebee said softly, gently grabbing one of Sari's hands between his much larger thumb and finger. She paused and looked up at him. It was a look that she was suddenly ashamed of her body. It had been so many years since she had found out she was not human, but she did not know her robot body. She had never explored it herself.


Bumblebee took advantage of this moment of dominance. Strangely, he now knew Sari's body better than she did. Bee let go of the teenager's hand. She stayed put, knowing now not to close the chamber. Bumblebee smiled like his usual sweet self. It was an expression that relaxed Sari. The physical side of their relationship had always been a game. It was a trial and error of finding out what worked. It was not only the difference in size, but their bodies as well. Sparks were something they had in common yet never fully adventured into.

The yellow bot sat down on her bedroom floor. He pulled her closer and gently placed his hands at her sides. Bumblebee's thumbs rubbed gently on Sari's exposed nipples as his head leaned in slightly to her spark. The redhead gasped even before Bumblebee's glossa touched her tiny spark.

Sari's body quivered lightly at Bumblebee's attention. He had just touched the aura of light around the spark. The speed bot would have to take slow, having to test what Sari was capable of. Noticing his human built girlfriend knee's were buckling, he took his glossa off the spark. It was followed by an empty whimper from the girl. She didn't want him to stop.

Bumblebee smiled softly and picked her up lightly. He sat the redhead on the edge of her bed. He leaned forward again to lick Sari's spark lightly. His hands did not ignore the organic parts of her body. Bee made sure to move his right pinky to rub against the girl's crotch. The girl moaned some more, almost wanting to throw her back up against the bed, but that would only pull her away from Bee's glossa.

They were unusual quiet for their actions. Normally words would be said or challenges made. This time was different. There was a strangely different mood in the air. As Sari felt a rush through her. Her organic and robotic parts both being toyed with sent a new sensation she had never felt before. Her spark felt so heavy from being enriched by energy. The teen's interactions with Bee in the past had lead to organic orgasms, she had never overloaded before.

Sari had felt Bumblebee's spark beating before during other times they had 'played.' What she felt from his this moment was different. The change was not Bee's spark but her's. She felt a pull, as though her spark was answering back to the yellow bot's beats. The human bot felt an ache because her spark was not joined to Bee's. She looked down at Bee and wondered if he felt the same every time they were intimate.
