I [F] 22 accidentally squirted all over my roommate's boyfriend

My roommate's boyfriend (let's call him Joe) has recently been staying over more than usual. He dropped by while my roommate was at work and I was asleep. I woke up late and was feeling very horny. I went to use the bathroom and while I was out, I didn't see anyone in the apartment, so I thought I was in the clear...

I went back to my bed, pulled out my vibrator and started fucking myself, while browsing Reddit. Just for clarification: my bed stands right in front of my door. As I am fucking myself with the vibrator, I'm also moaning REALLY loudly, so he must've heard that something was happening. Just as I'm about to squirt, Joe decides to come into my room, to ask me if everything was okay. He opens up the door and I immediately blast all over him.

Upon realizing what happened, I instantly got up and started apologizing, while also offering to help clean him up. He assured me that everything was fine and that he shouldn't have entered my room without knocking. After that he went to the bathroom, to wash himself up. I felt so embarrassed after this, that I didn't leave my room up until the next morning.

It's been a few days after what happened and neither of us have mentioned anything about it. He also doesn't seem to have told my roommate anything and I'm not planning to do so, either.
