Sex Contract with a 190cm 100kg Long-Tongued Sharp-Toothed Non-Human Man ~Bizarre Gourmet~

In an underground world, a merchant sells a rare surface delicacy of crab to his wealthy client, Uqbar. Uqbar is a massive man with a modified body featuring sharp teeth and an exceptionally long tongue, which he uses to enjoy the meal. As payment for the rare food, the merchant requests to have sex with Uqbar, who willingly agrees. Moving to the bedroom, the merchant tops the large client, who uses his long tongue to pleasure the merchant during their intense sexual intercourse. Afterward, the two share a relaxing bath while discussing their ongoing relationship and the merchant's unique regenerative abilities.
