After falling from a stepladder at work, I break both hands. I cannot even eat without help, so my son and his wife begin taking care of me. The rest of my body works perfectly well, however, and merely seeing my daughter-in-law makes me hard. Unable to masturbate, my sexual frustration grows worse each day. I feel guilty, but I cannot fight the physical urge any longer and finally ask my daughter-in-law to relieve me herself.
