Naked walk...or rather crawl

Three hours later you kneel naked, just as he ordered. He walks in and has two things in his hands. Leather collar and the leash. Oh, fuck. He walks to you and without asking for your consent (not like he has to do that) puts the collar around your neck. Then he attaches leash to collar and walks pulling on it. You obediently follow him, but try to deter him:

"Sir, you want to walk with me outside."

"Yes" he answers casually "I think one round around the lake will make both of us much good."

"But sir, somebody can see me!"

"Yeah that's possible. Why, are you afraid that I would share you with them? Who knows. Let's go!"

He's just talking, you are certain. Almost. You would prefer to walk slowly, but he pulls the leash, and you are **** to crawl pretty fast. You have to give him one thing: he's choosing the trail carefully, so your hands and knees are in no risk of being hurt. Still it's not easy to catch up to him while crawling. When you reach the other end of the lake, you relax a little. Maybe nobody is here, besides you two? As often happens you had this thought in the wrong moment. Because, seconds after, the jogger passes you two. He looks at you two with open mouth and you burn in shame. But Gerrow is calm and leads you further without paying the stranger no mind. You dream about being back in the cabin, but there is still a long way to go. On the other hand you know that with every move you are getting closer and closer. Finally you see it, and you are overjoyed, no more humilil...

"Here you are professor!" you hear the female voice from behind. Oh no! You hope that Gerrow will ignore it, but no. He turns around.

"Felicia, welcome" you turn around and see two women who are a little older than you. You recognized one of them almost instantly. It's a girl you saw on a photography, she was smiling while she was sucking a cock. She's pretty, not as much as you, but she has wide hips, nice round face and C-cup tits. You understand why Gerrow liked her. The other girl is shorter, has glasses on her nose. She isn't spectacular, but she could be describe as cute. But you are the only one naked.

"Hi professor" answers the blonde "this is Kendra. I was hoping that we three could have a little fun. But it seems that won't happen."

"Unfortunately I have to refuse" Gerrow answers "this is my..." he looks at you "****, fucktoy and a student."

"Oh really professor?" Felicia says, you bet that she is looking at you, but you are avoiding her eyes, it's easier to look at the ground "I thought that I was the only one. But you are still seducing your students."

"To be exact: she tried to seduce and **** me. But her plan backfired."

"She really tried that? She's not very smart then."

"Oh no, she quite dumb" said Gerrow. If you weren't already red from shame you would be now "but she has other assets."

"Oh yes, she's a real beauty. Professor what would you say for doing a little photo session with her?"

You raise your head. She's looking at you with playful smile. You don't like that.

"What do you mean?" asks Gerrow.
