Cought masturbating

So about 4 days ago I went over to my girlfriend's house just to chill for a few hours. As I arrived her 2 room mates were leaving to go bowling in the next town. Well my girlfriend and I ate dinner and watched scary movie on the television. Since I knew that her room mates were leaving I wanted to have sex since we were alone, but my girlfriend said that "she was not in the mood."

After the movie she went to take a shower and I was feeling horny. So I went into her room mate's room and logged onto her copmuter. Her background was her in a bikini so I stopped there. I took off my clothes and sat in the chair. I took a pair of underwear off of her bed and started to masturbate. Any way, just as I was about to blow my load both of the roomates walked in and saw me shoot a huge load into the girls underwear and one of them quickly got out her cell and took a picture.

I turned out that they had come home an hour early because they forgot that the bowling ally closes two hours earlier on Monday-Wednesday so they got something to eat and then went home.

My girlfriend was obviously very upset with me and both of her room mates were very disgusted, especially the one that I jacked off to. My girlfriend did forgive me, but the room mates are both very disgusted with me. Even worse is that they told some of their friends and showed them the picture on her cell. Obviously the word quickly spread around my campus and it's very imbaressing.

However, when her two room mates walked in it was very exciting and and got pumped. I found myself wanting to be caught by someone again, but I am too scared of who it might be and what the consequences might be. But both of the room mates and my girlfriend have sisters and one of the room mates has 3 so I kinda want to be caught by one.
