Female led relationships discussion

On Monday I made the big mistake of forgetting my key which is with my car keys downstairs, it appears Dazz unlocked himself, readjusted his position but also took the chance to masturbate a few times before heading up to bed, I didn’t find out until he texted me his confession. This happened on Monday and I have told him that I will punish him on Saturday ie tomorrow, apart from a really hard spanking with a bath brush and a 6 stroke caning does anyone have any good ideas for supplemental punishments, and should i take into account his confession, my feeling is no, but am i being too harsh He was due to be released Sunday perhaps I should delay for another week, or longer?
