You do it

Julia: I'll do it...

Lily: No, Julia, I won't let you... I have lost my honour already, that little more barely means anything...

Julia: But Lily...

Lily: No, don't argue about it...

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...

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

He takes his cock out of you and brings it up to your mouth. He strokes it a few times before sticking it into your opened mouth, while your face is still covered with Julia's 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...! You could barely swallow it all without water or something... But you managed to get it done in the end... You felt a strange mixture of cum and squirt, never felt before!

Lily (after coughing a little): 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 you could be involved in a sex with me! 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...
