Broken arm help

M (22) f (64) I broke my dominant arm and hand weeks ago and my grandma offered me one evening to come over and help me shower and told me wear my boxers or swim shorts but when she got me in the shower she started soaping me up and rubbing a rag over my chest and body while she started telling me “ maybe I should get these off you it’s ok I’ve seen you naked before you need to get a real shower let me help you “ I tried telling her no it was ok don’t worry about it but she pulled my trunks down fast and told me step out of them so I stood in front of her using my left hand to try and over my cock and balls while she laughed and sprayed me with the water hose and then told me “ do you wanna close your eyes while I wash it ?” I said “ no it’s ok don’t worry about it I can do it thanks “ but she told me “ oh come on just let me do it I’m already all wet and have this rag soapy for you !” Before I could argue back my grandma stepped into the shower fully and the water was running down her tank top and yoga pants she squatted down in front of me and gently pulled my hand away then started rubbing the hot soapy rag on my balls while she looked up at me smiling and asked me “ does that feel good ? Am I hurting you ? You’re making a face like it hurts? Are you ok ?” I tried with all my will to not get hard but I instantly got throbbing hard in her face and she said “ oh that’s the problem ! Oh my lord ! “ I said “ grandma you gotta let me out I can’t help it I haven’t orgasmed in weeks I’m sorry please forgive me” she just stayed squatting in front of me looking into my eyes without saying a word she opened her mouth and started sucking and moaning on the tip of my hard cock while she put the hot wet rag under my ass and sucked me like crazy for a few minutes moaning on me until I told her I had to cum and she ate it all but I stayed hard and she then sucked me a second time and swallowed even more . After she gave me two blowjobs she got me out of the shower and we spent some time watching tv before she left .
