My three sisters and I are no strangers to suppositories. We all got them from time to time, although the older two only rarely. Lisa, the third oldest and I both had, and still have frequent bouts of constipation. Although Mom much preferred giving us enemas, if time was too short to give us enemas, she would ease a glycerine suppository into our little poop chutes. I use the plural, because Mom figured if one of us was plugged up, the other either was or would be soon. Until we were around eight or ten, we really hated them. As puberty set in, though, we both realized that we were enjoying our suppositories and enemas. We didn't know the term "anally erotic", but we were both developing into full-blown anal erotics. We started feigning tummy aches to get the "relief" that we craved. Although we both loved (and still love) enemas, we both loved the sensation of Mom's finger poking a suppository deep into us. We both also liked holding our suppository until we were forced to poop. Mom and Dad divorced when we were 13 and 10, respectively, and Mom had to get a job. Cindy, the oldest and Marilyn, next in line, were never interested in their back doors. Lisa and I, on the other hand, were fascinated by anal insertions, and taking laxatives, suppositories, and enemas. In fact, we loved anything which gave us cramps and forced us to poop. Our house had a detached garage, with an apartment above. There was a locked side door with a staircase hidden inside the garage, perfect for private play sessions. With Mom coming home three hours after we got out of school, and working all day Saturday, Lisa and I had ample time to indulge in our shared kink. We spent many a happy afternoon and Saturday naked in that apartment, giving each other suppositories and enemas. Neither of us were into scat, but we enjoyed inserting several suppositories, and standing in the bathtub until we pooped unavoidably. We loved watching each other poop, and expel our enemas standing in the tub. We never played with it, just turned on the shower to wash it down the drain. After we cleaned each other out, we would push bananas or zucchini squash into each other. I can still picture Lisa with a zucchini in her pussy and a banana in her anus.
