Make it hard on him

"Forget it," you say, struggling against him. "I'm not making this easy on you."

"Oh, this won't be hard on me, I assure you." He laughs, a sibilant, hissing sound, and then he sinks his fangs into your neck. You yelp, your muscles tensing as the sharp sting turns into a cold burning as the naga injects venom into your blood. After a moment, he withdraws, and you feel the warm trickle of blood running down your neck and onto your chest.

"Did...did you just...poison me?" you gasp as your chest constricts. Your heart pounds and your vision dims. You're going to die.

"Calm down, that was not poison," the naga says. "The sssorcerer sssaid you were not to be harmed."

"Then what did you do to me?" Okay, maybe you're not dying, it's just a bit of a panic attack. You take deep breaths and the feeling fades.

"That was just to loosen you up a bit," he says, running his hands over your bare skin. To your horror, you feel your cock start to harden. "In case you didn't know, naga venom is a powerful aphrodisiac." He presses his cool, scaly body against your backside, and you bite back a moan as his slippery cock presses against your hole. You find that you can no longer resist, and as his slick rod slides into your body, stretching that ring of muscle, you don't even want to fight him. It feels so good, you rock your hips, trying to get him to fuck you, your hard cock slapping against the thick coils that encircle you.

"Please..." you gasp. "Oh, please..." He grunts and hisses as he grabs at your hips, his cool, slick shaft sinking into you again and again, slender and long, reaching deep inside of you, touching place that you had no idea would feel so good. Your cock leaks crystal drops of precum, your aching balls full and heavy, ready to spill your load. His thrusts grow fast and erratic, and his coils tighten around you as he cums, spilling his seed inside of you. You can feel it, cool and creamy, flooding your passage.

After a moment, he pulls out and the coils loosen, slipping away until you are free.
