With a sexy surprise.

Deep underground as you are you do not mark the coming of dawn, but those outside do, and the gongs resound through the shelters of the colony, calling it's people to the trials of a new day, yourself included. You groan and roll over, not wanting to get up after running with far to little sleep and none of it especially restful for the better part of two months when your arm smacks into, instead of blankets or a pillow, something soft, warm, and... Flesh Like? Curious as to what it is,* you open your eyes and raise your head to look, whereupon you see that it is in point of fact flesh, namely a naked woman, who also is starting to wake up!
