When writing you don't need to include sex to make the story erotic. I like to focus many times on the transformation itself being erotic.

"As she positioned herself on all fours on the ground, her fingers splayed apart, feet firmly bent behind her wrinkling her heels, she just twitched, ever so slowly, interchanging soft moans with wicked snarls as her mouth frothed, licking her lips with her tongue as it lengthened, playfully biting her lower lip, just enough to draw a trickle of blood as her canines grew. Her muscles spasmed beneath her clothes as her skin began to become slick from the effort of the change that was slowly overtaking her body. Her breaths became bated, deep, taking the air deeply into her, releasing it with harsh panting gasps. Every inhale her chest heaved, breasts swelled, filling her top. She blushed due to the sensations caused by those breasts as they seemed to heave into the lacey soft material of her bra, eyes fluttering as those lacey cups became tighter, squeezing her bosom, the friction of the expansion causing her nipples to become erect, the front of her top pushing out, neckline slowly plunging to accommodate her changing form. She felt a tickle on her skin, like electricity arching in and out of her as tiny hair began to sprout from once smooth flesh. She dug into the floor, scratching the carpet as her nails cracked and popped off, every one of them slowly shooting into darkness around her as blackend claws replaced them. She shuddered as a chill went up her spine, the discs of her back cracking and spacing themselves further apart and to accommodate this she arched and put her nose down into the floor, ass pointed up, trembling as it ballooned, straining her jeans, causing her panties to shift about as they were forced to rub against her body in a very flirtatious manner, caressing her softest and most private parts, the cottony material just shifting and rubbing against her in a normally obscene manner, but in this instance, just slowly and softly enough to elicit a muffled moan. Her face scrunched and began to protrude becoming canine like, and her ears perked up as they began to come to a point. Her senses felt alive, more alive then ever before, and her newly pointed ears picked up the faint sound of stretching leather from her shoes, as they groaned in protest as her heels grew swollen, toes claw like. Her rear swelled until the denim split, revealing the beginnings of a tiny tail tenting the soft material. Her top split open, along her back, showing how it glistened from the heat the change was bringing. The front of her jeans, the button popped, then zipper slowly descended as if an unseen hand was slowly yanking it down, and her newly forming snout could detect the faint aroma of desire as single moist droplet fell from there, hitting the ground with a soft plop, the emerging creature letting out a soft howl at that moment."

That's a semi erotic start to a vague TF. This interest can lead to a transformation that could in some ways be better then sex. Also that above is not from a story, just more of a spur of the moment thing. I shall read your story now though and comment later. Wish I saw this thread sooner.
