A longer rest than you expect

You drift off, barely even realizing as you drift between dreams of beds, and warm embraces, and men that smell nice. When you finally open your eyes, you realize that in addition to the twin in front of you, the other twin has joined you while you were asleep, and is hugging you from behind. They're asleep too, and judging by the sunlight coming in through the window, you spent the night here. The thought makes you go red, as does the sight of the sleeping face of whichever twin is right in front of you.

The three of you are pressed close together, and you realize, after a moment, that there's two hard somethings pressing against your butt and lower stomach. You swallow, and remember seeing something online about "morning wood." You tell yourself it's just a biological thing that men have, and it doesn't mean anything. Besides, you don't really want to get up, the two of them are very warm and comfortable. And with four arms around you, it might be hard to wriggle out without waking them.
