The first time it happens, it's a genuine accident. It happens because
she has to go really badly, and really should not have gone to tend to
the garden before going to the bathroom. She overestimates her ability
to hold it, and, while Marina is watering her flowers, she loses control
and wets herself. She feels her panties get damp, and looks down,
mortified, and sees the way it runs down her legs.

At first, it is an accident, but when she notices, a few days later,
that her flowers are looking better than ever before, she can't help but
wonder if it's more than a coincidence. One afternoon, she has to pee
very badly, squirming and dancing in the garden, but she does not bother
going to the bathroom, even though she has to pee so very, very badly.

She can't help herself. Once again, she loses control of her bladder and
pees right there in her garden. This time, it feels a bit like release,
like relief, and she's surprised by the way her breath hitches at the
feel of it. She's never thought about her body this way before, has
never felt her heart skip a beat while peeing herself. The next day, she
decides to take her panties off and squat directly in the garden, where
she empties her bladder with a sigh.

There is no denying that her flowers grow stronger and more vibrant, so
Marina continues to hold her bladder all day at school, waiting until
she is able to pee in her garden. She does not tell anyone what she's
doing, and nobody notices her strange new habit. Her beautiful garden,
however, catches a lot of attention, though she can't help but blush a
bit whenever she receives any such compliments about it.
