Sigh, Why Did I My Diet Shun?

A lament re a Writer's Cramp prompt. Once again, Summer is here, and I'm not ready.

         Summer is here with heat and sun.

         I must bare all to join the fun.

         Breath held, gut clenched, I pull, wriggle

         bathing suit taut, folds, and jiggle.

         Spandex stretched, seams strain and protest.

         Winter weight wedged from butt to breasts.

         For sun protection, prying eyes,

          a long shirt hangs past snow-white thighs.

         Twisting by the pool on a chair,

          I try to lounge with failing flair.

         My skin is slick, my face a'flush

         while vinyl webbing traps my tush.

         I can't resist. I start to dream.

          My cravings scream for cold ice cream.

         Damn the calories, sneaky cheats.

         They lie, mislead, yet seem so sweet.

         Summer is here, another one.
