Condom Mimic

Shapechanger. The mimic can use its action to polymorph into an object or back into its true, amorphous form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Adhesive (Object Form Only). The mimic adheres to anything that touches it. A Huge or smaller creature adhered to the mimic is also grappled by it (escape DC 13). Ability checks made to escape this grapple have disadvantage.

False Appearance (Object Form Only). While the mimic remains motionless, it is indistinguishable from an ordinary object.

Grappler. The mimic has advantage on attack rolls against any creature grappled by it.

Urethral Infiltration. If the mimic successfully grapples a creature and is in its true form, as a bonus action, it can attempt to enter any available orifice on the grappled creature. If targeting the urethra, the creature must succeed on a DC 14 Dexterity saving throw to prevent infiltration. On a failure, the mimic moves into the creature's urethra. While inside, the mimic cannot be targeted by attacks or other effects from outside the host.

Semenivorous. The mimic instinctively seeks out and consumes semen, which it finds exceptionally nourishing. A mimic that has recently fed is noticeably more robust and may have advantage on Strength checks for 1 hour.

Pseudopod. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) bludgeoning damage. If the mimic is in object form, the target is subjected to its Adhesive trait.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage plus 4 (1d8) acid damage.

Urethral Assault (Only while inside a host). The mimic violently expands and contracts within the urethra. The host takes 7 (2d6) piercing damage and must succeed on a DC 14 Constitution saving throw or have their speed halved until the end of their next turn due to excruciating pain and temporary debilitation.
