"They're back in from the field, you ready, Cat?"
You weren't really. You'd never even shown another girl your tits, excluding Keira. Then again it was your first time being brought to all fours and milked in a straw-lined stall too, so it was really a day of firsts. Sensing your nervousness as he opened the stall's door, Aaron reassuringly said "Don't worry, they'll love you." He waited by the door for you. "Come on out, Cat" he goaded.
Still a little bit light headed from the intense milking, you took your first few steps forward and out the door. You almost needed to focus on your crawling. Each 'step' on all fours elicited a 'tock' noise from the cowbell hanging from the collar fixed firmly around your neck which rang out throughout the barn. All the way Aaron walked beside you at your speed. You found comfort in that presence.
Looking up from the straw and your bell you saw two women. Like you they were on all fours. Unlike you, neither were wearing anything at all, not even a cowbell collar. Stopping, Aaron crouched down. "Eliza, Sarah, meet Cat. Cat, this is Eliza and Sarah, two of my best producers"
Sarah, to your right, was obviously quite a bit shorter than you, making her a good deal closer to the ground. Aaron moved to your hips and helped you to stand up, and the two girls in front of you followed suit. Sarah was quite obviously of some Irish descent with her fiery red hair and freckles. Standing, you'd say she was 5'1", a good 6 or 7 inches shorter than you. You couldn't help but unsubtly sneak a long peek at her boobs. Lightly freckled on pure white skin, they proudly splayed outward and to the sides, their size easily a respectable D or DD.
You glanced quickly at Eliza. Her perfectly round breasts - easily DD or E's - were especially remarkable given her tiny frame. They hung tightly to her chest, jutting directly out as she faced you. You couldn't help but feel a bit envious.
"Hi Cat!" they exclaimed. Sarah continued: "Aaron told us a new girl might be coming in for the first time. We just wanted to make your first time as fun as ours and say hi. Hopefully the ambience was ok, normally we only moo if Lorelei's in."
"Thanks" you said blushing, "So are you hucows?" you blurted.
