Perhaps this would be best – simply to go ahead and –

Her hips shifted and, unbelievably, I was slipping, so slowly, into her warmth, with no more fanfare than the look on her face, her eyes closing slowly and opening again, a beautiful, pained-looking smile as her body adjusted to the invasion of mine. 

I trembled.  My arms shook and my breath shuddered.  But I moved slowly, gently, even as Bella’s hands tried to press me further, deeper.  I had to control this.  I closed my eyes, astounded that the venom had not burst forth in my mouth yet.  Perhaps the man was taming the beast after all.

I arched into her and kissed her, holding my body still while I did so, because I was not certain I could manage both kissing and moving at the same time.  But her body writhed beneath mine, and I had to respond.  It was awkward, initially, as we both figured out what to do, how to meet each other’s hips, how long to allow our pelvises to linger before pulling slowly away and letting the measured thrust begin again. 

Venom began to trickle slowly into my mouth.  I ignored it.

Slow.  Excruciating.  Just what I’d wanted. And – judging by the look on Bella’s face – just what she’d wanted, too.

I never sped up, never drove in any harder; I merely tried to gauge my motions based on what Bella’s body seemed to be telling me to do. After a while, it became easier to follow her rhythms as her hands pressed into my back, my hips.  And the sensations …

Despite the venom I now had to swallow away, despite the fact that my body was much too hard and cold and deadly, I’d never felt more like a man than I did at this moment.

Bella’s eyes were vivid, locked on mine, and our ragged breathing met inside each other’s mouths as we strained to get closer to each other.

And after a while, miraculously, something happened. Bella’s eyes closed and her head turned away, her face burrowing into my neck.  I felt a contraction around me, hard, and then another, and another, and she cried out and whimpered as her body finished coming undone beneath me, for me.
