Consume and Convince.

Struggling to move at all even as the slug coats your upper back with more slime, you feel the slugs lips open and wrap around your feet. You freeze in your actions and gasp a little at the touch. Evidently the mucus doesn't seem to dampen any sensation of touch to your extremities despite it having tightened around your skin considerably.

Another squirt of mucus against your back allows it to flow over your big breasts, coating them and shrinking around them to give a sensation that makes you pause.

You feel numerous tentacles on the other side of the slugs lips, all seemingly pouring over your feet. Several larger tentacles wrap around your shins and begins to pull you back into the creatures soft maw.

Your arms and head take a liberal squirting of the slugs slime, coating your arms and fingers entirely. It also creeps around and seals over your mouth, nose, eyes and ears leaving just your nostrils clear.

Starting to panic, you start thrashing away at the slug but are unable to prevent it from slowly sucking you up into its mouth.

As your hips and consumed and you feel its tight but soft lips around your waist, a fleshy tube extends from the base of the creatures mouth to your cock. It takes a few moments for the fleshy tube to sink all the way down your length and sealing itself in a tight vacuum at the root of your cock. The tube begins a muscular undulation along your length that causes you to silently moan in delight.

You feel another limb raise itself up from the creatures mouth and position itself at your entrance. Wondering what that could be, the creature lashes several tentacles around your shoulders and upper arms and pulls on you hard, pulling you deeper into the creature...

... and impaling your pussy onto its hard and waiting cock. You silently cry out as your pussy parts to allow the thick and lengthy invader in. You feel it grind over your g-spot as it continues sucking you in, its lips curl up over your breasts, your arms give up the will to fight and are also pulled inside, leaving just your face exposed inside the creatures lips.
