Maybe

You suddenly feel very tired and you still can not use your legs yet.

You remember how high up you are and doubt that your in any condition to manage to climb down to the ground.

You decide to get some sleep and hope to get some rest and the use of your legs so you will be able to climb down.

Your dreams are full of sex with the harpies ending with them eating your corpse when they had finished with you.

You wake up the next morning with the full use of your body.

The harpies had been hunting and there was a stack of fresh fish. They gave you some.

Its a good thing you like shushi so eating raw fish did not bother you.

You were feeling a lot better after a good nights sleep and a belly full of food.

Then the harpies gave you a drink. As soon as it touched your lips you knew what it was and once again swallowed the lot.

You could feel your body stiffen. Your cock more than the rest of your body.

It could swear your cock was so hard it was stretching the muscle and your cock was getting bigger.

The eldest harpy came over and had a good look at your cock before once again squatting on it.

She started fucking herself up and down on your cock. She stopped and started rocking back and forth on your cock.

The other harpies were off doing their own things.
