Man, I just can't get enough of holoform asks. How about Roddy, Ratchet, and Nautica (and maybe Drift, tho we haven't seen his holoform, but why not?) receiving their first hickey on the neck? :>
(fans self) Oh boy! This got a bit steamier than I originally intended. XD
Rodimus: He doesn’t really notice it at first (he’s a little distracted at the time ;D) But once he does notice the marks on his neck he’s a bit confused. He’s got spots on his skin? Maybe there’s a glitch in the holomatter program. Once you explain to him the concept of hickies however, his face immediately starts to flush. “Oh,” he chuckles nervously. “That’s kind of… Slag, that’s kind of hot.” From then on he wears each and every love bite like a badge of honor. He’ll strut around the ship in his holoform mode just so he can show off the spectacular bruises along his neck and collar bone. Ultra Magnus has threatened to have him court marshaled several times for his obscene behavior (which of course, is partly why he does it.)
Ratchet: Having spent so much time on Earth, he’s far more knowledgeable about these things than most of the crew. He chuckles as you start sucking on the tender skin on his neck - a deep, rumbling sound that vibrates through your tongue. “Easy on the marks there, sweetspark,” he mumbles, “some of us have a reputation to uphold.” You both know that whatever bruises you leave won’t matter, as the only time he ever uses his holomatter form is for times like these. He grins as he brushes a thumb over a particularly large, red mark at his throat. With a low, rumbling laugh, he flips you over on your back so that your positions are reversed. “Okay, sweetspark, your turn,” he purrs, dragging his teeth over your collar bone.
Nautica: The heavy make out session was terrific, don’t get her wrong, but these marks along her throat are very disconcerting. Nautica momentarily panics, thinking something must have gone wrong – that you two had gotten too rough with your heavy petting and she had somehow suffered internal bleeding. (Swerve tells her that’s a legitimate concern with organics.) You barely suppress a chuckle as you explain to her that those marks are actually a sign of affection on your planet, and are perfectly safe and temporary. She blushes furiously, both at her overreaction and at the meaning behind the love bites. “I don’t suppose we could… try it again?” she asks hopefully, her eyes darkening with need.
Drift: He traces a finger over the hickies at his throat in front of your habsuit mirror with a curious expression. You shift awkwardly on the bed, running a hand through your hair and feeling your cheeks beginning to heat up. “I’m sorry, Drift. I got a bit carried away there. We can stop for tonight if you want.” He turns back to face you with a heavily lidded gaze. “Who said anything about stopping?” he replies in a husky murmur that goes straight to your groin. He brushes a strand of silver hair out of his eyes and saunters over to straddle you on the bed. “I want you to keep going,” he breathes in your ear in a husky rasp. “I want you to use that gorgeous little mouth of yours until every inch of my body is covered in your marks.”
