ask if you can join them as their breeding stock

You try to communicate as best you can, through sign language, that you wish to join their clan. They seem to discourage you at first, saying that only Tuskens can be part of their clan, or that's what you can ascertain. You emphasize that you don't wish to join as a Tusken, but as communal property. They discuss this among themselves for a bit, and then agree. They mount you atop a bantha, still dripping in their cum, and wrap you with a cloth and lead you back to their camp.

Once there, they treat you well, giving you water and food. It tastes foul at first, but you realize it's all that they have. They tie you up to a pole while they go off and hunt, and when they return they ravage you.

Sometimes, they take turns.

Other times, they are too impatient to wait.

You've heard tale of those that had been captured by Tuskens, led away and raped, but you are different. You volunteered for this life. You feel ashamed every time your cunt clenches around their cocks, rocking your body with waves of pleasure as you orgasm from their continued use of you, until one day that changes.

The Tuskens bring back another woman, bound, just like you were. They tie her up next to you, and you begin to talk. You learn she's the daughter of a moisture farmer, who had little to look forward to in life. She also offered herself freely to the Tuskens, trading their care for her in exchange for their use of her body.

You realize that you're not alone in these desires, and you begin to feel less and less shame, losing your previous self and embracing your role as the fucktoy of the Tusken clan.

During the night, while they are away, you remain bound, kept in their tents. You pass your time talking to the other captive.

During the day, when you're not preparing meals for them or helping them sew clothing and tents, you embrace your role as their cocksleeve lovingly. It becomes the highlight of your life, and you even begin to develop favorites.

Though nothing excites you quite the same as being fucked by multiple at the same time.
