The marine's words from behind him didn't do much to help his discomfort, and it seemed like each new inch of the dark man's cock that went in him only made the pain worse.  Chaz was slowly rocking his hips, feeding one inch after the other and pulling out between thrusts before adding more pressure.  Peter shifted on his knees, spreading himself a bit as Marcus said though his hole continued to clench around the thick cock being pushed into him.<br/><br/>"Nnn...nnnngh...oh f-fuck...f-fuuuck..."  Peter groaned out softly, his teeth gritting as Chaz continued the onslaught.  It felt like the man was pushing a tree trunk into him though in reality he was just well endowed, and Peter was made ever aware of this fact.<br/><br/>He lifted his head a bit to look up at Marcus when the kiss landed up on his head.  The older man was leaving his side for the moment, and it made Peter whimper.  His head returned to being buried in his arms which were crossed under him, but Chaz never relented in thrusting into him.  The man had half his cock in already, but after a moment, he felt the slippery feel of lube being drizzled around the remainder of the man's cock and his stretched pucker.<br/><br/>Peter had no idea what the two men behind him were doing.  In the forefront of his mind was the pain and discomfort of taking the dark marine's dick into his inexperienced hole.  He heard the sounds from behind him and a few words passed between.  It seemed Marcus was going to fuck Chaz, and he began to wonder what that meant for him.  "Ahhnngh...mm...fuck...oooh...fuck..."  Peter kept saying softly, hissing out the words as his muscles flexed.  A sheen of sweat began to appear on his skin and his breath became hurried as the sensation of taking the man's sizable cock flowed through him.
