Dungeons & Dragons meets The Office. I like the concept, but it feels like your prose is largely perfunctory. I'd like to see a little more worldbuilding early on.
In terms of writing, you have big blocks of text that should be broken up for easier reading, and when it comes to dialogue especially your sentences tend to run together which makes them difficult to read. On top of that, many of the chapters are very short, no more than a long paragraph. I would recommend, if you ever feel like polishing some of the early chapters, to spread things out and add a little more background material.
The questions prompting the next chapter are a mixed bag; most of them are workable, but sometimes get
this one where the question is "What is Kira doing" (no question mark) and the answer is "What is Kira doing?" For a fairly linear path that doesn't make much difference, but if you ever intend to branch out later, that kind of thing can be annoying, or turn people off from contributing another option because there isn't a very obvious choice to be made.
As for sex scenes...
Her skirt hiked up around her toned midsection as she gripped his hips with her knees. She was so wet he could feel her hot juices dripping on his thighs, as she guided his massive new cock into her. Her cunt was the hottest, tightest thing he had ever felt. She leaned over him as she began to bounce, planting kisses up and down his neck. She moaned “Oh fuck, you’re so big!” as she gyrated, unable to take him any deeper.
One hand drifted down to her clit, as she bucked and shuddered on his cock. “Please sir, I want to cum. Can I cum?” She sounded flushed and desperate. With a few commands he had reduced this absolute Amazon of a woman into a begging cocksleeve. “Not yet,” he grunted, grabbing her hips “ Take it all.” He pulled her down bottoming out inside her. She didn’t stop, grinding harder on his cock as she gasped in pleasure.
He grabbed her tits and guided one nipple into his mouth and applied a small amount of pressure with his teeth. She groaned in delight. Her cunt reacted immediately, clamping down on his dick, like it was trying to milk every drop out of him. The pressure sent him over the edge and he erupted into her. Shot after shot filled her and the sensation was too much. She came, shuddering and whimpering on top of him. The small office reeked of sex. She collapsed on top of him, panting and disoriented.
Good attitude, but remember this isn't a race. Feel free to adjust the pace, indulge yourself a little. Focus on what they're feeling, physically and emotionally. Sex is about more than how big the cock is and how tight the pussy is; think about what their relative sizes are to each other, the difference in height, weight...whether she has fangs...what she smells like, what they sound like when they moan, how orc women blush, the size of her breasts relative to his hands, etc. etc.
In other words, it's not bad, but there's room to indulge yourself a little bit. Have fun!
Other than that, I think you've got a fairly strong plotline going what with the mental coercion on the various monster girls. It might be nice to see paths that lean in on specific kinks (breeding, bimboization, submissiveness, etc.) but follow your own inclinations on that one.
