Juice the lemons and place the strained juice and the bodies into a large pot. Add the sugar to the pot and muddle with the lemon bodies and juice for 2 to 3 minutes. Remove the lemon bodies, add the water and stir until the sugar has dissolved.
Strain the mixture into a 3-quart glass container and add the cucumbers. Steep for 1 hour. Add the gin and stir to combine. Serve over ice.
