Feeling like a douche

My husband has always hinted that he wouldn't mind waking up to a blow job so I took that as something he wanted me to do. I was having trouble sleeping tonight so I thought why not. I snuck over to his side of the bed and started gently kissing his neck and when he rolled over and started to wake up I started working my way down to his chest he then said I need to sleep and scrunched his face at me. At this point I was straddling him and sucking on his nipples. So I just got off apologized and went back to my side of the bed. Now he is tossing and turning and sighing loudly and I just feel like an ass for waking him up. I doubt this is going to be given a second try...😳
