After a millennia of torturing (physically and mentally) the unfortunate fools who fall into its grasp the Sarlacc gets bored and strikes a deal with its latest victim, Boba. In exchange for freedom, Boba lets the Sarlacc fuck him. Go wild with the tentacles!

Bonuses
+Some aphrodisiac or sex pollen included. Maybe the Sarlacc decided to switch up its torturous neurotoxins for something more... sensual.
+The Sarlacc is sentient and (mentally?) communicates with Boba. Full on taunting and bantering between the two.
