Had sex instead of helping his mom and now she isn’t a big fan of me /u/katie498 Sex

22F dating a 23M. Had holiday over their house, good time. Told his mom I would help her clean after as a good gesture. Ended up getting side tracked and having sex with my bf when the last few guests were gonna leave so I didn’t help her and ended up losing track of time to have sex with him which he initiated because he was horny. I was like not really at first cause he had family downstairs, so I guess his mom walked past his room and heard something because she later made a comment you and that gf of yours were too busy having sex to help. So I kinda looked bad in front of her and I feel super bad, she def hates me now what do I do?
