You were out deep into the forest, in your usual spot near a river. You often come here because it is quiet and beautiful out here. Also you can perfectly go swimming in the clear river.
Today you planned on going into the water again, you make your way towards the water removing your clothes until your underwear as you walk. What you dont know is that at the moment a Tardis appeared nearby somewhere in the bushs. The Doctor came out scanning the surroundings. "Where the hell am I..." he mutters under his breath, his breath hitches as he hears water splashing. He follows the noise till he saw you in the water. He keeps hidden at first not wanting to scare you off.
He didnt knew who you were or where he was... he didnt even knew what year it was. As he thought of what to do next he occasionally stealed glances in your direction watching how you looked in the water. He accidentally stepped on a stick, breaking it. He hoped you wouldnt hear it...
