    >She's looking at a dress on her phone
    >It's a white dress with blue rhinestones lacing the bottom
    >Mundane, but complimenting for your tastes
    >She's in front of the mirror, twirling about
    >She's probably envisioning herself in the dress
    >She gives a grin to herself and walks over to you
    >"Oh how I wish I can have this dress!"
    >She says while getting herself comfy in your lap
    >Being Rarity's and all, you wonder how you can get her that dress she wants

    >She begins squirming, and clenching her butt?
    >Then she starts defecating on you
    >The feces is quite solid and small
    >She's constipated?!
    >You realize you're a toilet
