My girlfriend’s mom lives with us and she has her own room. It was about midnight and I just got out the shower. She is usually doesn’t come out after midnight because she worked early morning ( no longer working ) so I went to jerk it in the living room because I didn’t want to do it beside my girlfriend. And my girls mom walks out as I’m fully erect just stroking and she doesn’t say anything but looks for a sec and then just walks right passed me and goes outside to smoke. I’m stuck between embarrassed and turned on because why didn’t she say anything and how long was she actually looking?
