I tried to sleep, but after a minute he had the audacity to rub his cock up and down between my ass cheeks, trying to get some additional stimulation! I rolled over, facing him and said:
"Hey! Obviously you need some more punishment, as you didn't seem able to control yourself!"
He apologized profusely, and confessed that he was too turned on to sleep.
"Why don't you sit down on that chair then," I told him, "and use my hands to tease yourself for another hour, OK? When your hour is up, then you can come... back into bed and snuggle with me, without waking me up!"
