I have chronic health issues and a disability, which is a lifelong struggle for me. It impedes my body in different ways, and makes it easier for me to get sicker, for longer, than what others my age would get. A couple of weeks ago I wasn't very well and it necessitated a few trips into town for doctors visits and various kinds of testing. Because I live roughly forty minutes away from my doctors clinic, and because my relatives I live with, were away for the night, I ended up staying with my grandparents for a night (they live literally two minutes up the road from my doctors clinic). This served the purpose of having someone who could safely drive me to the clinic, but also someone would could keep an eye on me through the night in case my condition worsened. My grandfather is in his early 80's, and not in the best health himself, so he goes to bed fairly early. My grandmother is in her mid 70's, and relatively good health, so she was sitting up a bit later with me as I was watching TV in the living room. I was struggling to sleep due to breathing issues, and all round just feeling like shit. So I was watching a movie late at night, while puffing on my Ventolin when needed, trying to be mindful not to overdose on it. I called it a night around 11:40pm, at which stage my grandmother had already gone to bed a few minutes before. After tossing and turning, I was able to get to sleep until early hours of the morning when I woke in a wet mess of my own urine. Unfortunately for me, the side effects of the Ventolin were kicking in. Honestly feeling embarrassed and even shittier, I got up, pulled the sheets and blankets off the bed, and then left them on the floor of the bedroom as I started to go through my bag to try and find spare clothes. I grabbed some spare pants and a singlet and then started to trundle out of the room. I went to the bathroom, changed myself and gave myself a quick wipe over with some wet wipes, before throwing my wet clothes on the floor in the corner. Walking back to the bedroom, I found my grandmother staring at the linen on the floor. When asked about it, I explained what happened and she offered to help me out with fixing the bed back up. This caught me a little off guard, as I wasn't sure how she would handle hearing that a 28 year old wet the bed. I dragged the dirty linen to the bathroom, while my grandmother grabbed fresh linen to throw onto the mattress. I helped her tidy some of the linen on the bed up, and was getting ready to sit up in bed to read, as I explained I was worried about wetting again, when my grandmother offered a suggestion for my issue. My grandfather has a condition called Chrones Disease. It effects his bowels, and has been caused by a lifetime of alcoholism and a bit of a poor diet. My grandmother said that my grandfather had a few old unused packets of adult diapers, that no longer fit him, and she offered to get me a packet so I could try them through the night (in order to save linen and help me with my sleep). I thought it might help, and so my grandmother told me to take my pants off and lie on the bed while she went to get them. I followed her instructions, and was lying on the bed with nothing around my waist, feeling pretty awkward. When my grandmother returned to the room, she brought in a packet of diapers and a bottle of baby powder. Instructing me to roll, she slide an open diaper underneath me before powdering my arse cheeks using her hands. When I rolled back, I could feel my cock start to pulsate and grow. I honestly tried fighting it, but not being someone who gets touched much, the touch to my arse felt good. Better than it honestly should have. My grandmother started to pat powder around my thighs, and across the bottom of my stomach and around my groin. My small cock had grown into its full length, four inch erection by the time she was done, and I was beyond embarrassed at the stage. I was apologizing when my grandmother noted that: "This will cause leakage issues." Now, my grandmother isn't the most patient person in the world. In fact, she can be quite rough when it comes to doing house chores, because she tries to get things done as fast as possible, to the point where she has chipped dishes while washing them and damaged skirting boards while vacuuming, because she rushes everything. I was hoping my erection would subside, and my grandmother waited a few minutes, but started to get impatient. She simply said to me: "Lie back and don't say anything." I did as I was told, and she wrapped her hand around my penis and started to work my cock with her hand. It felt weird, but good at the same time. I knew it was wrong, but it still felt pleasurable, which for me made me feel awkward. The most awkward part was when my grandmother noted that I was enjoying myself because I was smiling and moaning once I started to reach my climax. When I came in her hand, my grandmother cleaned me up, taped my diaper up firmly and threw the new sheets on top of me. She turned the light off, told me she would see me in the morning and then mentioned that if I needed to be changed, to let her know. I don't think she said anything to my grandfather about it, and nothing came up about it the next morning. I'm wondering now, if it might be a bit forward of me to ask my grandmother if she could help diaper me again sometime, and see if maybe she might be interested in touching me again.
