We had a good session last night. Sitting next to each other on the sofa I was giving him hard downward blows with my knuckles. He got so hard as I stroked him in between hits. We had great sex after but it's the hardest I've hit in a while. He's still sore today, wearing sweatpants out of necessity. He says not only are they tender but he feels it up into his stomach. I guess we were hitting them for at least 15 minutes, they certainly reddened up and I swear they were somewhat swollen. I wonder how long recovery will take?
