From the back.

Bending her over the hump of the divan, you spread her netherlips with the very tip of your cock. Taking control of her hips, you tell her, "I'm going to move now." Selas looks over her shoulder, bites her lip, and nods.

Going as slowly and smoothly as you can, you push her walls aside with your cock. Her hands claw and bunch up the fabric as you fight for every millimeter, when you hit a barrier. Pushing aside your surprise that succubi have hymens, you tell her to brace herself, because this might hurt. She swallows and nods again before telling you to do it. With a steadying breath, you jab forwards with your hips.

Selas yelps in pain, but so do you. You didn't manage to break her hymen and bounced off it instead. Your next two attempts meets with the same result and you can hear her start sniffling again. But you're too horny to let something like this stop you. Spreading her legs wide, you brace her against the hump so that she can't escape forwards. Pulling your hips back almost all the way and grabbing onto her shoulders, you drive yourself into her with as much force as you can. Your cockhead squashes against her hymen, but you keep pushing through until it finally breaks.

You don't stop there. Grunting and snarling ferociously, ignoring the fluttering wings and her tail slapping your chest trying to get you to stop, you keep forcing yourself deeper and deeper inside her until the only points of contact you have on the floor are the tips of your toes and Selas is hanging off you, completely speared on your cock.

To describe the feel of a succubus' virgin pussy, is like trying to describe a new color or a new smell. You'd have more room to move if you'd have stuck your cock through a needle's eye. The heat of a thousand exploding star systems would be ice cold in comparison to her depths. Every square nano-meter of her walls feels like it has a hundred mouths kissing your cock, and each mouth has a hundred more. Your legs give out and you fall on top of her. And in the time it took for your brain to register that it did, a trillion little fireworks went off all along your body.

Underneath you, Selas has dropped onto her front, her limbs limp at her sides. Her eyes have gone completely blank and her tongue is lolling out of her mouth. Her breath is coming in as short, shallow gasps, but only when she remembers how to breathe. You make the mistake of touching her ear with your thumb, to check on her, when her entire body convulses and her howl sets the entire room shaking with her orgasm.

There is no resisting. No control. No pain. Only pleasure.
