Chastity and orgasm denial discussion

KH and I went to a neighborhood get-together over the weekend. She enjoyed herself immensely, with just enough alcohol for extra zest. When we got back, she promptly locked us in the bedroom and unfastened me. A powerful orgasm came quickly for her, though I was left wanting more. KH promised round 2 after dinner, but the drinks eventually won out as she drifted off to sleep. Unable to resist, I lifted her damp panties to my nose and took full advantage of them. The night passed with me free, those very panties resting near my head. This morning, I admitted my little transgression to KH. She was pleased by my honesty but insisted on retribution.

KH told me to share this mistake here and send in three fresh punishment suggestions tonight. Usually, that means extra time in the lockup plus a good spanking. Got any clever ideas?
