Leaky Ceiling

When a woman is hitting climax with no stimulation other than visual. So she then tries closing the flaps to reduce the outtake. It then drops and dribbles out, becoming a "leaky ceiling"

"Oh shit, not again" "But he's so fit" "I should try close it up" "Oh no its going all over!" "It's like a leaky ceiling!"

Leaky Ceiling

When a man ejaculates above / over top of their partner and it lands, or drips onto their head. Just like if your roof was leaking rain water and it was dripping onto your head.

"I didn't know where to ejaculate, so I treaters her to a 'leaky ceiling'
