It had been years since the team of auto bots lead by Optimus prime had come to earth, only a few since the new team at least. Originally bumble bee, strong arm, sideswipe, and grim-lock, but now also Optimus prime and drift too, the team was nearing the end of their mission on earth. Strong arm, the only girl on the team, never once in battle, under protocol, let out that she, even as a large robotic alien, had needs like any other girl. She tried her hardest to satisfy herself every night while the others were recharging, reaching under her pelvic plate to feel her large robotic pussy. She played around with her cyber-clit and shoved her long fingers deep inside her hole. Rubbing her fingers all around her huge pussy lips, until her radiant blue cyber-cum oozed out of her. But fingers could only do so much, she needed something better.

Today during a briefing she was thinking about what she could do to satisfy herself again.

"I could get one of the boys to help me... but drift is so unaffectionate, and Optimus would never... neither would bumble bee, and grim lock could crush me, and side swipe..." she listed in her mind before shivering at the thought of getting that close to side swipe. She thought for a while, Even during missions. Occasionally she thought of what all the boys were packing under their crotch plates. She liked what she thought she would see in drift, bumble bee, and Optimus, scowled at the thought of side swipe again, and was scared of grim lock. Try as she might though, some how her mind kept coming back to side swipe. No matter what she thought sideswipe would be the only one willing to help her. More trouble was that none of the bots could ever get any alone time, always being a large open scrap yard. Strong arm thought even more about this he finally settled on a secluded back part of the shop that no one went to, except for strong arm.
After another missions end, sideswipe was gloating as usual but strong arm didn't care this time.

"Hey sideswipe! Come with me!" Strong Arm told.

"What for? And since when would I listen to you!" Sideswipe retorted.

"Just do it!" Strong arm said dragging him to her little secluded area.

"Alright ya brought me here, you want something, or something?" Sideswipe asked annoying.

"I only want a favor, something along the lines of this..." she said before griping side swipe's waist and bringing him closer for a kiss. Side swipe struggled for a bit before he felt pleasure in locking lips with strong arm, and began moving on his own in the kiss. They held each other until the kiss was done and came apart.

"W-what was that, and why did I like it?" Side swipe asked a bunch confused.

"I-I-I, I don't know, if you didn't like that you can report me to the lieutenant, oh I'm a nervous wreck!" Strong arm blurted blushing and stuttering as she began to tear up.

"Hey hey hey don't worry, I-I said I liked it." Side swipe told. Side swipe hugged her shivering body as she nearly sobbed into his chest plate.

"Sideswipe?" Strong Arm called out.

"Yeah?"

"Truth is I-I have needs and I thought, you could help." Strong arm told.

"Well I mean, I know that needs means more than some kisses now and again and..." side swipe spoke before feeling strong arm's hand rub his bright red crotch plate. After the shock passed he felt pleaser in her hand rubbing close to his dick.

"Could I..." strong arm asked.

Side swipe didn't protest and allowed her to undo the clasps on the side of his armor, revealing a hard as steel metal cock. Strong arm continued by licking it with her cyber tongue, making sideswipe moan quietly. As strong arm continued, even beginning to suck him, sideswipe got a peak at strong arm's rear end. Her thick cheeks sticking out of the back of her crotch plate, he was amazed he never noticed it before, he couldn't help but grip the closest cheek given his situation. Strong arm felt his grip and loved it, she deep throated him to show she liked it. With his view of strong arm's huge ass, and the amazing blow job she gave, side swipe came after a bit, shooting cyber cum down strong arm's throat. Some cum dripped out and she licked it off, making side swipe hard again. Strong arm decided to give him even more of a show as she got up and began to unclasp her own crotch plate, bending over to show off her ass in the bright white cyber-panties she was wearing. Side swipe couldn't get any harder as she got fully undressed, even undoing her breast plate and cyber-bra to reveal her large metal tits. With her body bare she went over to side swipe and sat facing him on his lap with her legs spread on her knees, her pussy positioned directly over his wanting cock. She lowered her pussy, sliding it onto his cock, and they felt pleasure as strong arm went up and down on his cock. As she bounced so did her boobs in sideswipe's face. Side swipe gripped her moving ass as she went up and down, while strong arms hands were playing with her breasts in sideswipe's face. Her slick wet pussy ready to cum, she slammed down on his cock. Strong arm let her wet warm cyber cum drip out onto his still hard cock. Strong arm fell over exhausted onto the ground, sideswipe lied next to her. Exhausted they Lied next to each other, strong arm finally satisfied with her cum soaked pussy.
Mean while just outside of view behind a wall of the scrap yard, bumble bee stood staring as their sexy detour had ended. He walked off knowing he had to confront them at some point.

A few days later, strong arm was polishing herself at the car wash she liked when bumble bee walked up and cleared his throat to get her attention.

"Oh! Lieutenant, is there something you need me for, a mission or anything?"

"No strong arm I just wanted to talk to you about what you and sideswipe did a few days ago." Bumble bee explained.

"O-oh, d-did sideswipe say something?" Strong arm asked scared and blushing.

"No. I saw." Bumble bee

"S-sir you were watching?" Strong Arm asked again.

"N-no of course not, I caught the end, but as you know doing anything like that with team mates is in violation of at least three protocols."

"Y-yes sir, but I'm more scared of the very specific regulation listed right after the whole section of protocols I violated." Strong arm told.

"I read that part, sad thing is I'm required to enact this so called "punishment"." Bumble bee continued.

"I understand sir, I broke the rules and this is what it gets me..." strong arm told.

"Well this is tough for me strong arm, I know we both just want to get it over with." Bumble bee answered.

"Yes sir."

Strong arm began by bending over the wall of the car wash they were at, sticking her bottom out behind her. Bumble bee got behind her and unclasped her crotch plate to reveal another pair of white panties, which were left up for now. Strong arm braced for what happened next, as bee's hand slammed down on her rear ended with a mighty spank. Strong arm felt a sting as bee continued, smacking both cheeks back and forth. Her ass was getting bright blue as it got warmed. Slap after slap was given in perfect unison on both cheeks, her back side getting darker and darker. Strong arm winced louder and louder as her bottom got more and more sensitive to the slaps. Strong arm was getting teary eyed and blushing like crazy as her ass kept burning from swat after swat. She bit her lip hard and winced at what happened next, as bee lowered her white panties, baring her ass to the next round of spanks. Her already blue ass was getting darker even faster as her bear bottom was unprotected from bee's unrelenting hand. Her ass was reaching navy blue before bee delivered two last powerful slaps to her bear behind. After her legs kicked up at the same time from the jump, bumble bee stopped and stood her up to face him. Strong arm's face was teary and red as she furiously rubbed her well spanked stinging ass.

"Have you learned your lesson cadet?" Bee asked authoritatively.

"Y-yes sir." Strong arm answered timidly.

"Are you sorry?"

"Well I'm sorry too, for being required to say that line. I hope things will go back to normal okay, and that this doesn't ruin our friendship." Bee told.

"Of course not sir, you were just doing your job, even if, it, really stings." Strong arm reassured while continuing to rub her sore rear end.
