With a tussle to his hair, the boy swallowed slightly before being guided to one of the dark nubs of flesh on the man's chest.  His hands hesitantly came up to rest on either hip where the man's towel was still wrapped.  Peter's mouth opened and his lips came in contact with the marine's nipple.  He sucked lightly at first, his tongue flicking over it as he held onto the man.  His eyes closed as he tried to please Chaz.  The young man began to notice the differences between the two men, even now.  Chaz was smooth and perhaps a little less beefy than Marcus though that was not an indication of less muscle.  The man was quite ripped, so Peter attributed the difference to bone structure and genes.<br/><br/>He felt his 'daddy's' hand grab at his towel, pulling it away to leave him exposed.  Peter blushed a bit, his cock uncovered to reveal its hard state, but he didn't stop paying attention to the man's nipple.  "Mmmf..."  He moaned softly against the dark chest, the nipple vibrating between his lips.<br/><br/>Marcus' words were encouraging, and he didn't understand how it made him feel so good to be called a 'good boy' by someone he'd just met...someone who he came to know as 'daddy.'  That, too, was not understood either, but he knew he liked it...when he called the older man that.
