Anal Bondage to Cure Claustrophobia

Anna De Ville can't take elevators or stairwells without her chest tightening and her mind screaming. Doctor Francesca Le has read every detail in Anna's file, including how much Anna loves getting fucked in the ass. She tells Anna to close her eyes and picture the deepest pounding she's ever taken. When Anna opens them she's bound, wrists and ankles locked. Her breathing spikes. Francesca moves fast. She spreads Anna's cheeks, licks the tight ring, presses a thumb past it, then two fingers, then three, working the hole open until her whole fist sinks inside. Anna strains against the ropes, terrified of the closeness yet soaking from the stretch. Francesca keeps driving her arm in and out until Anna's ass swallows to the wrist. She swaps to a long steel plug, then a fat blue dildo, each one pulling the rim wider until it blooms into a pulsing heart-shaped gape. Finally she fits an anal speculum, cranks the blades, and leans in to lap at the pink, glistening walls now on display. Satisfied with the stretch, Francesca unties Anna just enough to drag her to the stairwell. There she bends her over the cold steps and sinks a strap-on into the wrecked hole. With every thrust the walls seem to close in. Anna's breath catches, fear spiking at the same moment her climax rips through her. She comes hard on the strap, shaking, and the panic dissolves. The tight space no longer owns her.
