Though Marcus was being merciless in his quest for self-gratification, he wasn't entirely unintelligent about it... surprisingly enough.  Though he was groaning and grunting in an increasingly frantic way, he was keeping his brown eyes fixed on the pink ooze beneath his face.  He was staring in wide-eyed pleasure as bubbles broke the surface in a steady rhythm.  He knew what they represented, and knew that he literally held Seras' life in his hands.  For the moment, his was the power of the gods...<br/><br/>The power Seras felt from him, however, was probably centered in her groin area.  She was struggling, pushing upward with her face to breathe, but she seemed to be putting more of her efforts into keeping time with his rhythm.  He'd seen the pleasure on her face before he'd pushed her under, and he felt how her body was responding to his.  Even though he was playing with her life, she was still trying to enjoy his body...<br/><br/>After not even a minute, the bubbles suddenly stopped as Seras ran out of air to expel with each of his thrusts.  This was it.  All he had to do now was hold her under, and her struggles would grow more frantic, before weakening and fading...<br/><br/>The thought brought him over the edge.  He threw his head back and howled, beast-like, and his seed erupted from his body, discharging into hers with force that was unusual for him, even as his hips' rhythm became erratic.  He could feel her still jerking beneath him... and a gasping laugh escaped him as his simple mind decided she, too, had just drawn pleasure from the experience...<br/><br/>After yet a few more seconds, Marcus finally pulled free of her, and he allowed himself to flop back into the ooze, his shoulders barely clearing the stuff.  He finally let go of Seras... but it was up to her to bring herself back to the surface, if there was enough life left in her to do so.
