Spy on naked Judy

Rebecca has nearly killed you with blueballs, and her hot, barely-18-year-old sister is naked just inches away from you.

What do you expect?

You strain to hear over the thumping of your heart, listening to the rustling of a soft towel against warm skin on the other side of the door.

After a minute, you hear the door on the other side of the bathroom swing open, and you hear it swing back again - but not shut all the way. Maybe if you weren't so desperately horny you wouldn't take such a risky move, but you quietly grasp the doorknob on Rebecca's side of the bathroom and slowly and silently open the door.

You see the small, dark bathroom ahead of you and notice the door on the far side slightly ajar. You quietly step into the bathroom, holding your breath as you ease the door closed behind you. You're standing in the darkness, invisible to someone standing in a lighted room, and you inch your way to the other side of the bathroom.

You can hear Judy moving about in her room, and you hear the springs of her bed squeak. Finally, your eye reaches the thin line of light in the door frame; you can see perfectly into Judy's teenage bedroom without being seen in return. And what a sight!

Judy sits on her bed, her back propped by pillows against the wall, completely nude. Her breasts are large and magnificent, with big areolas and puffy nipples, softly resting behind her phone, which she's looking at closely. Her legs are slightly apart, revealing a pussy shaved mere moments ago. Every inch of her body is yours to feast on, and you take a perverse pleasure in getting comeuppance at her having seen you naked earlier.

Then, just as you reach down to touch yourself, Judy does the same.
