I found something to haunt your dreams and fuel your nightmares: DINOSAUR EROTICA.
I purchased one AS RESEARCH OKAY and, my oh my, it is delightfully disturbing. Here's a taste of In the Velociraptor's Nest:
Azog stood, back to the wall, clad only in damp buckskins, waiting for the beast to slash at her torso until she lay helpless and bleeding on the damp cave floor. She wondered if it would kill her first, or if her limbs would be sliced from her body as the beast gorged on her.
Instead, it reached out with a classed hand to snatch at her damp animal hide as it clung to one shoulder. Azog felt the kiss of sharp claws against her skin as the hide slid from her shoulder and exposed on naked, heaving breast. The raptor paused, curious, sniffing at her as she pressed desperately against the wall.
A reptilian tongue, stiff and hot, dashed out to lick at the tender, naked flesh so suddenly exposed. Azog gasped at the touch, then gradually relaxed as her body warmed to the intoxicating sensation of the beast's flesh against her own.
She wasn't sure if her sudden arousal was because of her earlier thwarted climax in the cool stream, or if she was just desperate for one last pleasant sensation before being torn limb from limb by the great, scaly beast. Either way, Azog relished the rasp of its tongue, hot and rough, on her sensitive skin.
I just want to point out that it took two people to write this 18-page book. That is all.
