Red-RazzleBerry What are you guy's kinks? If you don't have any, then what is the naughtiest thing you've ever thought about? (Warning, some adult topics... And vivid descriptions of adult topics... Obviously)

David bit his lip, clearly flustered, Jack however seemed completely unphased by the bluntness of the question.
"Causing pain obviously, I believe there is a word for it, however I cannot remember it right now," Jack shrugged.
"Wait... Causing pain... Turns you on?" David sounded almost scared to ask.
"Indeed," Jack nodded.
"So whenever you're working you...?" David really didn't want to finish his sentence.
"Yes, it does cause a... Reaction, however I am highly capable of controlling my urges," Jack replied.
"Wow," David felt like he knew way too much.
"What about yourself David?" Jack asked, genuinely curious.
"Oh... I... I honestly don't know if I have any, I'm not really a sexually active person, in fact I've never even- actually nevermind," David sighed.
"You have never what?" Jack teased.
"I'd rather not talk about it, anyways, naughtiest thing I've ever thought about..." David's eyes shifted towards Jack. He was pretty tall, not to mention strong... Plus his teeth seemed to be sharp, fangs it seemed. He could probably make some pretty deep marks in someone's skin if he bit them... Making all kinds of suspicious marks on their neck... Claiming David as his own... Wait no! He didn't mean to think that! Oh but just look at how built he is... He could easily pin David down and use him in ways that- NO, BRAIN, STOP. Jack noticed that David had grown very red, and he seemed to be... Drooling?
"David?" Jack asked, trying to snap him out if his trance. Upon hearing Jack's voice saying his name, David let out a small squeak.
"Um... Yeah?" David shook slightly.
"Are you alright?" Jack was concerned.
"Mm-hm, I'm fine I just... Need to go get some air or something like that," David chuckled. He left the room, waddling. Jack frowned in confusion, but simply shrugged it off.
