Even though she wasn't wild about the consistency or taste of it, she expected that was mostly due to having never tasted it before. After she had the time to get used to it, she decided that it really wasn't all that bad, and didn't have any qualms about swallowing it as she'd been told to. By the time his cock had stopped pulsing in her mouth, she'd actually started to kind of like the taste of her brother's cum, and surreptitiously used her lips to milk his shrinking shaft of any remaining drops as she slowly pulled her head back before letting him slip from her mouth. As she moved to stand up again, she proved she'd done what she was supposed to by saying "There, I did it", only to hear the man with the gun say "You sure did, missy!", with a brief laugh.

When asked "That was pretty good, wasn't it, kid?", Robert was ashamed by his enthusiastic "Yeah!"

"Well, the next part don't feel as good, but it's almost as fun", the armed man said. Directing himself to Carla, he said "Okay, missy, time for you to sit down and spread 'em so Junior can get his licks in!", drawing laughter from the two men behind him. Despite feeling herself blushing, Carla tried as best she could to maintain her composure as she sat down in one of the armchairs and moved her legs apart- only to be told "Nah, not like that. Scoot forward so your ass is on the edge and hang your legs over the arms. You don't want your brother gettin' a crick in his neck, do ya?"

It was only a few moments until Carla was positioned to the man's satisfaction, causing her to blush even harder at knowing the sight she presented to everybody.

Seeing that his sister was ready, Robert wasn't surprised when the man told him "Go on, kid. Get your face in there and find out what fresh young pussy tastes like. Trust me, it's good!"

After moving in front of the chair Carla was in, Robert moved to sit on the floor; as low as the chair was, he knew he wouldn't be comfortable kneeling, and he suspected he was going to be there for a while. Though he didn't know it, Robert's attitude closely matched his sister's: as much as he hated being forced to do things with his own sibling, there was also part of him that welcomed the chance to learn and do things he'd heard of and wondered about.
