They tested her again, tested the very fibers of her toned muscles. A finger inserted into her cleft, tasting. Curiously of the smells and texture. Penetration happened slowly, filling her small hole. The thing in her body stretched as she gasped. An intense burn started, nothing had ever touched her there. A sticky fluid rushed into the virgin orfice, filled her bowels with lubricant.
Her stomach clenched, misunderstanding filling her chest. The arm started to withdraw, she cried out, it quickly pushed back in. The arms holding her legs and feet secured themselves tighter. The tender flesh between her legs held apart roughly as her bowels were bred.
She felt as if she were being split in two. Bursts of air filled her mouth as she tried to breathe it in. Her body began to shake when the small fingers between her legs filled her other hole. Those fingers circled around, twisting upon themselves. Pushing further and further, feeling the steady pumping through the thin wall of flesh.
She felt her breasts being wrapped tightly, felt the tendrils around her ribs. Felt so full of this creature she was sure her body would burst. A mad thing started to happen, everything started pumping at a manic pace. The bindings tightened. Her holes stretched painfully, pulling her body to places she would never go again.
Then she felt it, felt the gush of viscous fluid inside of her. Felt it in her most sacred of places. She swallowed the parts of it in her mouth.
Everything loosened as she rose to the surface. The creatures pushed back into the caves in the murky dedepthspths. They watched quietly as she scrambled out of the water. Her trial had just begun, if her body could handle the gestation and birth of their kind. She would be granted her ultimate wish. If it could not, the creatures would be released from their confines and granted freedom. With her family taking their cursed place.
They would know by the sound of the tribes drums.
