My mom walked in 😳

I’m 18 and I still live with my parents. So I was in my room with my boyfriend, he was laying on the bed waiting for me to get ready to leave. I never wear a bra at home so when I took my tank top off and started putting my bra on right when my mom walked in! I was facing my boyfriend which made it kinda awkward 😂 she knows we’ve had sex before so I guess that’s why she didn’t make a big deal about it. She just said “Gosh, no warning?” Like ummm you barged into my room, how was I supposed to give a warning lol. But this isn’t first time she’s done that. Usually I already have my bra on tho so it isn’t as bad.
