Sex Monster Saturday: Tentacle Monster

We're going to start off a tradition of posting homebrew sex-monsters on Saturdays. First up, a monster whose very name cracks grins on the faces of those who've watched a decent amount of hentai. And for good reason. The tentacle monster excels at providing bondage-like sex with an aberrant, almost eldritch, theme. Any kinky fantasy world would be remiss without one of these. What's more is that they tend to be very difficult to defeat in said worlds. With all that in mind, here's our stats for a tentacle monster:

Tentacle Monster

Size/Type: Huge Aberration
Hit Dice: 20d8+240 (330 hp)
Initiative: 3
Speed: 10 feet (2 squares), swim 20 ft.
Armor Class: 30, touch 15, flat-footed 31 (-2 size, +8 deflection, -1 dex, +15 natural)
Base Attack/Grapple: +15/+42
Attack: Slam +28 (1d10+15 plus aphrodisiac slime)
Full Attack: 12 slams +28 (1d10+15 plus aphrodisiac slime), 8 slaps +28 (2d4+7), 1 bite +28 (1d10+7)
Space/Reach: 15 ft./30 ft.
Special Attacks:

•  Improved Grab (Ex): If a tentacle monster hits with its slam attack, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. No initial touch attack is required. Tentacle monsters may grapple as many as 12 medium-sized or smaller creatures, or 6 large-sized creatures at the same time.
• Constrict (Ex): A tentacle monster may choose to crush an opponent, dealing bludgeoning damage, after making a successful grapple check. It deals 1d10+15 bludgeoning damage in addition to the damage dealt by the weapon used to grab.
• Swallow Whole (Ex): Tentacle monsters may choose to devour a grappled medium-sized or smaller opponent. It can attempt a new grapple check (as though trying to pin the opponent). If it succeeds, it swallows its prey, and the opponent takes bite damage. While inside the tentacle monster the creature takes 2d6+12 acid damage every round it remains inside the creature.
• Aphrodisiac Slime (Ex): A tentacle monster that hits with its slam attack smears its opponent in a powerful aphrodisiac slime. The target must succeed on a fortitude save (DC 22, Con-Based) or be uncontrollably aroused for 1d6 minutes. Creatures that have already resisted or have already been subjected to the tentacle monster's slime in the same day need only succeed on a DC 11 fortitude save to resist the effects.
• Aphrodisiac Gas (Ex): The air within 10 feet of a tentacle monster acts as a potent aphrodisiac. Any living creatures that need to breathe air that pass within 10 feet of the creature must succeed on a fortitude save (DC 22, Con-Based) or be uncontrollably aroused for 1d6 minutes. The effects of the gas are independent of that of the tentacle monster's Aphrodisiac Slime ability and the resultant durations from each effect stack. However if a creature has already been affected by the gas in the same day need only succeed on a DC 11 fortitude save to resist the effects.
• Breed (Ex): A tentacle monster typically chooses to mate with creatures that it grapples. It usually uses its genital tentacles to either pump its victims full of sperm (if male) or eggs (if female). If eggs are implanted inside the creature, they usually hatch within 1d4 weeks. While a creature is impregnated with a tentacle monster's young, they are exhausted after every full-night's-rest and suffer a -5 penalty to movement. If it uses this ability on a creature, then it will relentlessly mate with them for as long as it can before leaving them unconscious.

Special Qualities:

• Spell Resistance: 30
• Damage Reduction: 10 (magic/slashing)
• Regeneration (Ex): Fire and acid deal normal damage to a tentacle monster. If a tentacle loses  body part, it regrows the lost portion in 1d6 minutes. If a tentacle is removed then two more grow in its place in 1d4 minutes.
• Fast Healing (Su): Tentacle monsters heal 1d6 hit points worth of lethal damage every round at the beginning of their turn. The only way to disable this effect is to disembowel the creature's brain.
• Darkvision (Ex): 60 ft.
• Tremorsense (Ex): 60 ft.

Tentacle monsters are usually about 15' tall (with 30' long tentacles) and weigh about 14 tons.
Lurking deep within forgotten corners of the world below, tentacle monsters are infamous for overwhelming their prey with their many tentacles and consuming them. But what they are far more well known for is sexually violating adventurers unlucky enough to cross their path. Those who have survived encounters with these creatures describe them as horrid, vile creatures purely interested in reproduction and food.

Prone to stripping their victims of their attire and injecting their orifices with eggs or sperm, tentacle monsters are known to amass huge piles of loot stolen from their victims. Some speculate that they value the stolen belongings like trophies, others say that it's purely a coincidental result of their sexually delinquent behavior.
