The husband handed his wife a large glass enema kit, filled with warm water and a gentle cleansing solution. She looked at him nervously, unsure of what to do. He explained that this would help loosen her bowels and make her more prepared for the upcoming anal stretching.
He helped her position the tube and nozzle, showing her how to gently insert it into her anus. As he watched, he felt a rush of excitement. He couldn't believe he was about to push his wife's boundaries in this way. She winced slightly but bore through the discomfort as he began filling the bag with the solution.
When he was done, he instructed her to lie down on her side and hold the fluid inside for as long as she could. He watched as her asshole attempted to stretch around the now-full bag. It was incredibly erotic for him, knowing that soon his own cock would be filling that tight space.
