Here's the red demon character I've been working on. Subject to change but I like this design so far.

As you'll notice red demons have flared beast cocks, mostly bc, well, it ensures breeding. The head is a ramming shape which allows for compression upon penetration. It goes in easier than it looks. However, beware, as the head enters easily it conversely retracts with greater friction, aided by grippies. The glans engorges inside and acts as a dam, completely gripping and tugging on your insides. It's not so much the thrusting in but the pulling back which provides such sensation. You'll definitely understand the term being "dug out". The head scoops and "scrapes" your insides. This means the harder you pull back from it the tighter it grips and suctions your insides. Kind of like a Chinese finger trap.

Once inside the cock can't really be ejected, at least until ejaculation. This makes them very confident as they know they'll completely seal up your hole and fill you with every ounce of their demon seed.
