One way to find out!

Ethan was a bit smaller then Arcee, expected but he didn't mind, Arcee sauntered over to her little corner of the garage where her large bed was.

She didn't need one but was grateful for a soft surface to lay on, she got on the bed and spread her legs with a smirk. "So, think you can handle me?"

Ethan smirked back and walked over, he. Got on the bed and rubbed her rather large pussy, she bit his her lip. "One way to find out." He answered as he could feel the fluids leak out.

Whoever upgraded her body did a fantastic job.

"Ahh~ hey, careful, this is my first." She warned as she moaned.

"Oh? I guess not many want to try fucking a transformer, but I'm one to explore." He grinned as he removed his clothes.

Arcee blinked at the size of his cock, it was bigger then she expected. "Are you going to stick it in?"

"Not yet." Ethan walked to her face and pushed her head to the side and slapped his cock against her cheek. "First, I want you to suck."

Arcee looked into his eyes and took it into her large mouth, she bobbed her head and Ethan could see the bluish saliva coating his cock, energon spit?

Ethan bit his lip as her suction was pretty strong, he grabbed her head and bucked his hips.

Arcee narrowed her eyes and sucked harder.

'Her mouth is different from the other girls.' Ethan noticed as he continued to fuck her mouth, he reached over and groped her tit, the dark grey nipple fit in his palm, he squeezed hard earning a moan from her.

"That's it." He grinned, Arcee pulled away and licks his cock, her tongue was light blue.

He pulled his cock away and positioned himself on her chest, letting his cock lay between her breasts.

"Always going for the tits?" She smirked as she pushed them together around his cock.

"Talking about my preference?" He asked while moving his hips and biting his lip.

"Hmm chatter does go around." She hummed as she felt him titty fuck her.

Ethan moved his hips in a fast pace, he realized that he might need to kick things up if he were to really please her.

He grabbed her nipples and squeezed hard as he thrusts between her large breasts.

"That's it, keep going!" She reached down and rubbed her pussy.

Ethan couldn't stop himself from cumming. "Cumming Arcee!" He warned.

"Let it all out!" She ordered, Ethan did as told and let it out on her face and tits.

"Fuck, your tits were great! I can only imagine how your pussy feels like." Ethan breathe a bit unevenly.

Arcee took some of his cum onto her fingers and tasted it. "Well, why don't you get a feel?" She winked.

Ethan got off and moved down to her legs, he positioned herself between her legs and his cock sat on her pussy lips, he used partial demonic transformation to make his cock bigger, Arcee's eyes widened and she smirked. "Pulling out the big guns?" She teased.

"Trust me, you'll love this." Ethan smirked as he slammed his cock into her!

Arcee let out a loud scream, throwing her head back as her Cybertronian pussy was stretched out, never having anything in it before made her tight!

Ethan grunted as he felt her pussy squeezing his cock. "You're tighter then I expected Arcee."

"I told you this was my first!" She snapped with an annoyed expressed, which turned to pleasure as Ethan moved his cock in and out of her slowly.

"Well, that face of yours tells me that you forgive me." He smirked.

"Grr.. fine... Ohhh~" Arcee moaned as Ethan thrusts faster into her, an idea coming into his mind, he used his chakra arms to grab onto her breasts and massage them.

Arcee's moaning doubled when he did this. "Fuck! You're squeezing too hard!" She complained but her moans were so cute, he just kept going.

Ethan was seriously enjoying this! He already fucked the twins and Jenny but Arcee's size made this a whole different experience. "Let's see if I can make you cum faster." He reached down and felt her up until he found her clit and massaged it.

Arcee's eyes widened as her whole body started to shake. "Wait! Too much!" Her breasts being massaged, her clit under his rough tough and his cock stuffing her was too much for her!

"Don't hold it in Arcee!" Ethan slammed his cock into her and was smirking. "I want to hear you scream."

Arcee threw her head back as her mind was going blank. "Ethan!!!!" She cried as she came hard, squirting light blue cum all over his cock and squeezing it tightly.

Ethan gritted his teeth as he felt her squeezing. He slammed deep inside her and came inside, letting out ropes of cum fill her pussy.

Arcee slumped on the bed and was staring at the ceiling as Ethan finished cumming and pulled out of her and the chakra arms disappeared.

"... You're full of surprises." Arcee commented as she put a hand on her abdomen.

"Yeah, so I'm told." Ethan went for his clothes and put them on.

"Primus that was amazing." Arcee mumbled to herself and looked at Ethan. "... Doing this again next time?"

Ethan smirked. "Definitely." He walked over and kissed her lips, he walked out of the garage with a wave.

Arcee looked down at her pussy and decided to keep it inside.

Thankfully she was unable to get pregnant.
