No place to Hide (a Destiel/Saberial Story)

This is very much a self indulgent story fuled by my love of both the aliens franchise and supernatural. So this is a crossover of the two. This is marked as mature because if the violence and gore of it, as well as there being smut, so there is a xenophilla warning as Castiel and Gabriel are aliens in this.

Now for the summary;
it had been a routine hunt, clear out these bugs and chase them back to their hive, but Dean ends up caught by a blue eyed xenomorph who seems to have taken a liking to him. Castiel, as he names the beast is a lot more intelligent then they where told Xenomorphs where.
Gabriel is the fourth oldest of his siblings and the most unknown of the 'archangels', he has seen every reaction to humans about to die. Or so he thinks, yet this human, his Sam, shows emotions and cries. Maybe a bit of study it required, maybe Gabriel can not be a disappointment to Micheal for once by getting valuable information on one of their enemies.
