Ready for My Daily Groin Massage, Sweetie?

My stepdad got injured, and my mom is out of town, so it's my responsibility to take care of him however he needs. The issue is that he hurt his groin! How am I supposed to massage that area? I even need to give him sponge baths and rub... everything. I guess that if I'm already helping him with his dick, I should do it right. It's not fair that he can't milk it just because Mom is not here. Anything to make him feel better. Maybe he can just close his eyes while I suck his cock and ride it?
