Sun grabbed a fistful of your hair earning a few select swears and curses from you. In the other hand, he held a syringe with an unknown clear amber-colored liquid.
"The more you struggle the more this will hurt pet." Sun cooed as he got on one knee pulling you close and pinning you to his chest. "By all means don't stop on my account, this is going to happen either way." The needle was bigger than you expected. It felt like a wasp sting on your neck and the substance almost burned as it entered your bloodstream. "There now, don't be afraid to tell me how you feel through the process. Though some effects are in my notes," He tilted his head and eased the hold on your hair slightly. "I'm very curious to see how you react to this particular elixir."
"I-I…" You stumbled back slightly holding your neck as his hand stopped you. His eyes roamed over you, observing and calculating. It was subtle- the tingling all over. "M-Moon-"
"He'll be back later." Sun shut down your fleeting thought of a distraction. "In fact, he will adore seeing you influenced by this." Sun scooped you up and carried you to his office before sitting down at his illuminated desk. The holopad screens appeared as he waved his hand and started writing things down. You tried to comprehend their writing- their language even. The symbols and lines were extremely difficult to keep track of- and you knew they wouldn't let you attempt to learn. You were a lowly test subject to them. Sun purred and nuzzled the top of your head and he leaned back in his seat, his lidded blue eyes fixated on you while occasionally flicking to the transparent screens.
"You're very quiet suddenly, perhaps that is notable."
"I just feel… light." The air itself felt like it was brushing against you, the slightest movement was getting more agonizing.
"Hmm I see." You shifted in his lap earning a soft gasp from the alien. "What else are you experiencing? You see," He leaned his head on a propped-up hand in thought, a smirk starting to cross his mouth. "Most humans experience light-headedness." You nodded, and your face started feeling warm along with the rest of your body. "You seem to be taking longer to develop other symptoms so we're going to speed things up a little." He helped guide your hips so he could adjust a now very obvious bulge under his garments. You whimpered and grabbed his shoulders for stability as you felt his cock brush your inner thighs. Being in nothing but a flimsy medical gown made it easier for them at any time- not ideal for you. Though you couldn't deny the arousal right now as it inched closer you’re your heated now dripping core. "You're so wet for me already pet, such a delight." He pushed your hips down onto his cock earning a moan from you. He was bigger than Moon- though Moon would shift how his crotch appeared- Sun was more equipped for something else. He groaned and pulled you back to his chest as he reached over to type on the screens. You couldn’t help but to clench around his length which was wiggling inside you. "Ah- this is fascinating." He reached around to lift up your gown and rubbed your clit.
"S-stop-" You squirmed in his lap weakly- the unknown drug in your system making it near impossible to resist.
"Your vitals are showing me that you're enjoying this, very much." He growled in your ear. "Naughty little thing." Your legs were shaking as the pleasure increased in your lower belly. "You'll be close soon. It would be a shame if it stopped suddenly. It might hurt even."
"I c-can't-" Your back arched as his free hand grabbed your wrists, holding them to your chest and keeping you close. This whole time he wasn't even thrusting into you. The stimulation from his hands on your clit and the occasional pulsating inside you was enough to bring you close to the edge.
"Moony will be returning soon. I'm sure he'll love to see you like this too. We have much to discuss as well so get comfy pet."
