Peter moaned as the finger pressed into him, and it was quickly followed by the feel of something slippery and wet oozing down to coat the finger and his entrance.  "Ahh...nnn..."  He whimpered, trying to relax, but that wasn't an easy task given the situation.  He had a rather menacing marine behind him probing his entrance though luckily, Marcus was nearby.<br/><br/>His eyes looked up to the man as his hair was petted.  Peter nodded before turning his eyes to the thick shaft before him, his lips leaning in to give it kisses at first.  The head had begun to leak slowly, the fluid smearing on his lips before his tongue slipped out to lick them and lap at the head.  "Mmm...aammnnn..."  The boy moaned out as his attention was focused elsewhere, his body beginning to relax.<br/><br/>A second finger prodded his entrance as the boy slipped his pinkish lips over the crown of his daddy's cock, sucking on it gently at first as his eyes closed.  He didn't have to do much work as Marcus took hold of his head and slowly began to thrust his hips, sliding his cock deeper into Peter's mouth.  The head bumped the back of the boy's throat, and he concentrated to allow it past.  His tongue rubbed under the shaft, licking at it and savoring the musky flavor.<br/><br/>The boy brought one hand up to wrap around the remainder of the shaft, squeezing it firmly while his other cupped the rather full balls in his hands.  They were heavy as he held them, massaging them gently before tugging on them a bit.
