Billy had finally fallen into a restless slumber, although still anally filled by The Plumper's member, it had finally stopped thrusting in and out of him. Evidently, it too needed to rest. As Billy hung there trapped, he felt the creature begin to stir again and he moaned at the thought of being bred more. But something was different. He could feel one of the creatures arms wrap around his body, hugging him close, and suddenly it thrust up, even deeper then before, fully hilting him to its base as he felt his ass touch it's hips, and he came once again. It was making sure he wasn't going to get away. The creature dropped from the ceiling and landed on the floor, and begin to HISS. From the depths of it's tit prison, Billy heard a HISS in response as the creature slowly began to move to the left.
Unseen my Billy, The Plumper had been disturbed by another. One who desired Billy, it's mate, and was presenting a challenge. They looked almost identical in appearance, although if Billy couldn't see it, he would say its member was smaller, since he was so intimate with his capture's current member.
As the two circled each other, hissing and screeching, Billy moaned again as he slid up and down the member of his captor once more, with each step it took. That spurned on the Challenger as it charged and began to grapple with The Plumper, grasping at its breasts, trying to get at the prize inside. Billy begin to get glimpses of the other beast and could see its thick, fuckable lips, and similar large, nipple-less breasts. He groaned in shame, he was so turned on, he began to find these creatures sexually attractive. He caught sight of the Challenger's dripping member as the two continued to wrestle and realized they were fighting over him.
As the Challenger swung a claw, it knocked The Plumper's breasts apart, and the two creatures locked arms as Billy fell forward with a scream. His mouth wide open, Billy fell face first, onto the dripping member of The Challenger. Billy's lips barely fit over its head, and as he gagged to try and spit it out, the creature thrust up, burying another inch of it into his mouth. The two creatures let go of each other, one grabbing onto his hips, and the other, under his arms, and the two began a tug of war of his body. The Challenger would pull forward, fucking his face, as the Plumper would pull back, fucking his ass. Billy gagged and cried as both his holes were possessively filled, as slowly the tugging slowed, and the two creatures settled into a rhythm. Evidently a compromise had been reached, and the two were okay with sharing the poor chief. Soon his ass and mouth were filled at the same time, pushing deeper and deeper as the two bred each hole.
Billy tried to scream every time the creatures dick would leave his mouth, but it would fill it just as quickly and pushed its way past his gag reflex into his throat. He could do nothing to stop it, but hang there and weep, as his own dick betrayed him and sprayed cum on the station floor.
