night-water cum is the splooge that several cadets leave in the glass of water you keep on your nightstand after they jack off into it.
When I wake up in the morning, I always have night-water cum in my glass and the taste of my roomies' jizz in my mouth!

night-water cum is the pearly-white cumshots of other guys who jack off in the water glass of nightstand water a guy drinks during the night when he's thirsty.

Some of my roomies are leaving me night-water cum -- I wake up to get a drink and my cup is full of their cumshots!
