Gave a BJ while he was asleep

Keli • 20 years old been in in my current relationship for 13 months
So, as the title says, this morning a gave my boyfriend a blow job while he was asleep. He works 12 hour shifts five days in a row. So, I don't see him much! But I have a couple hour window to talk, play games, and sex before he goes to bed. This morning he made me come/orgasm and then said he was tired and that he's gonna pass out. I knew he still kinda had a boner, so I decided why not, since I feel bad that he didn't cum while having sex with me. So later on, I text him while he's at work and asked him if he was awake for it. 
He tells me he had no clue that it happened! I was laughing so hard, but it was sad because it was the best blow job I have ever done and he was asleep for it xD
