Ahhhhh almost got caught

So my husband and I only have sex we don't use vibraters or anything ( or so he thinks) so I was getting in to my bi weekly masterbation thing almost at climax and my husband walks in keep in mind my husband doesn't know about my little toy. So he walks in and I vary quickly turn it off and put it between my legs. I feel so guilty but he doesn't always want to have sex when I do and TBH he can't make me orgasm. I feel so bad but I low key thinks he knows about it because he just lets me take long baths. Idk maybe if I ask him he might get me a new one ( I have had the same one for 4 months and it's starting to give up). But I do still feel guilty about it. What do you lady's think I should do. Is this considered cheating?
