So do you always masturbate naked on top of the bed? Unless the answer is yes, you’re good to go.
I’ve even found an illustrative gif:
See how the pussy is hidden, UNDER the bed covers? That’s how it works. No one can see your pussy either, so as long as you don’t moan too loudly you’ll be fine to edge away morning and evening. No exhibitionism involved at all.
What’s more, unless it has shared showers, you can do it in there too! Brilliant!
Just, don’t use a vibrator.
It might not be waterproof.
