Sadistic Mulengro tortures Derek's balls

A sadistic mulengro binds Derek’s wrists and ankles with tight ropes, pinning him to a surface. The mulengro leans in to kiss his neck while gripping his testicles, twisting them hard before pulling his head down to suck his erect cock. One hand slides between Derek’s legs, fingering his asshole as he takes deep, rough thrusts into the mulengro’s mouth.
