Julia does it

Julia: I'll do it...

Lily: No, Julia, I won't let you... You have lost some of your honour already, I won't let you suffer this too...

Julia: No, I have gotten myself locked up here, it is my responsibility to do all I can to free myself, without tarnishing your honour...

Lily (thinking): If you knew all of this was because of me, you would agree, that it was my responsibility to do this all myself... But I see, I can't convince you...

Guard: Whatever, make up your mind! I just want an opened mouth next to my dick soon!

He takes his cock out of her and brings it to her mouth. He strokes it a few times before sticking it into her opened mouth, while her face was still covered with your juice. As he does he cums right away. He must have spoken the truth, he really wasn't having sex for weeks as his load was thick as hell...! She could barely swallow it all without water or something... But she managed to get it done in the end...

Lily: Right, we have done what we promised you, now let us go!

Guard: Fine ladies, it was a pleasure! Should you want to repeat it, find me at the barracks!

Julia: Just get lost already!

Guard: Ch, still can't appreciate how lucky you were, that you could swallow MY cum! You will beg for my dick in the future, I promise you that!

He leaves frustrated. Now, time to get moving!

Lily: We must go before we are seen!

Julia: Yes, I agree, lead the way!

Lily: Well... The problem is, there is no clear path out so far...

Julia: And how do you suppose to get out?!

Lily: The other guards are at their posts, but when we give the signal, George will distract them and we can slip away! He is waiting under this window beside the wall.

Julia: Great! And how are we going to signal him from up here, without the guards seeing or hearing us? If we shout to him, they will hear us, if we lean out, they will see us!

Lily: That... is still not decided...

Julia: Surely you we can think of something!

Lily: Hm, I have an idea! How about...
