[MFF] my girlfriend roommate walked in on us . No we did not stop

So for context my girlfriend of 6 months lives with a roommate , we are all in our 20s and she is the youngest of all three of us. I have offered my girlfriend to move in with me if she wants at anytime and we could split my rent , but for now with COVID and all she just lives with her friend for now.

About a week ago I head on over to my girlfriend’s flat to chill and all and like most times , one thing lead to another in the mood and began having sex. Normally we do it in her bedroom but since my girlfriend said her friend roommate would be away for the day to visit her parents , we decided to do it in the living room – kitchen area. Also we normally are partially clothed as well just in case her roommate needs us for some or to stop if need be quickly. But on this day we decided to be butt ass naked , fucking against the wall, on the couch , bent over the tables anywhere we could. So the entire day we fucked like rabbits for hours since we had some alone time assuming no one would come back. Well…
