2 years passed since Ironhide and Sideswipe got spark-bonded. They were happy together.

One day, Ironhide was walking out when he saw some human girls flirting with Sideswipe. And worse, Sideswipe wasn't doing anything about it! "What's going on here?" Ironhide asked, breaking the silence.

Sideswipe jumped and looked at Ironhide. "Hi, sweetspark!" Sideswipe waved. But Ironhide heard something he wished he hadn't.

"You're so hot. Let's have some fun in my room. Just for tonight." A girl flirted, seductively.

Ironhide blew a fuse. "What the frag?! He's my sparkmate!" Ironhide exclaimed. The girls ran off, frightened.

Ironhide growled and stormed off. He dampened the bond with Sideswipe. A week later, Sideswipe hugged Ironhide from behind.

"Hey, baby. Whatcha doin?" Sideswipe asked. Ironhide kept quiet and didn't look at his sparkmate. "Sweetspark? What's wrong?" Sideswipe asked.

Ironhide just got up and walked away.  He went to his room and locked the door, feeling coolant prick his optics. He sat on his bed and finally released his tears, feeling his spark ripping to shreds.

One day, Sideswipe had enough. He walked around, looking for Ironhide. He stopped dead in his tracks, finding the weapons specialist.

Ironhide had a blade and loaded gun to his chest and head. "Ironhide, no!" Sideswipe exclaimed. Ironhide faced Sideswipe, coolant streaming down his face.

Sideswipe slowly approached the mech, carefully taking the blade and gun. Ironhide broke down sobbing from heartbreak.

"Hide? What's wrong? Why are you avoiding me?" Sideswipe asked. "I'm scared...of losing you. When I saw those girls... flirting with you and you not saying or doing anything about it....I thought you were gonna leave me. I cried myself to sleep every night and when I was alone. I got depressed." Ironhide sobbed.

Sideswipe embraced his sparkmate, hugging him tightly. Ironhide just sobbed quietly in his neck, not knowing how to feel.

"I'm only yours, Hide. I'm yours. I love you and only you. There now. Stop your crying." Sideswipe comforted. Ironhide calmed down and wiped his optics.

"Activate your holoform and turn into your vehicle mode." Sideswipe ordered. Ironhide obeyed and Sideswipe got into the back seats of Ironhide's alt mode.

Ironhide then activated his holoform and did what Sideswipe did. Sideswipe started taking off Ironhide's clothing, till he was completely naked.

Ironhide took off Sideswipe's clothing, till the other mech was naked. Sideswipe got turned on again at seeing Ironhide's scar-covered body.

"Like what you see?" Ironhide asked. "Yeah. I always get turned on by seeing your scar-covered body, holoform or bipedal." Sideswipe admitted.

Ironhide kissed Sideswipe passionately, slipping his tongue in his mouth. Sideswipe shivered and moaned, battling Ironhide's tongue.

Ironhide eventually won that battle and was now on top of his sparkmate.  Sideswipe then started thrusting on Ironhide, gentle but fierce.

Sideswipe moaned a little bit. "Shh! Don't let anyone hear you!" Ironhide whispered. Sideswipe nodded, half eagerly. Then, they both came and snuggled.

Ironhide opened their bond again.
