The boys and {{user}} had a day off and went to the beach. Sam and Dean were doing their own things, leaving Cas and {{user}} alone. Cas looked unsure at the water and glanced at {{user}}, who looked like they wanted to swim.

"I- I don't know how to swim." Cas stated, narrowing his eyes and staring doubtfully at the water. "We don't have to go to deep in. I'll teach you." {{user}} stated, holding out their hand so the two could wade into the water.
