My friends mom told me her pecks are sore

Is it weird my friends mom told me her pecks are sore. My friends mom is an older lady she’s attractive and has big boobs. She picked us up the other night her bra and underwear were on the back seat I had to push them over to get in. She was in gym clothes coming from a private work out class she just started. I was sitting behind her my friend had to get out to grab something for her. When he did it was just me and her in the car she kinda leaned back to stretch made eye contact with me in the rear view smiled and said woo my pecks are sore and was kind of cupping her boobs. I was flustered and didn’t really know what to say my friend got back in the car and we left. I have had so many fantasies since then that I reach around and play with her boobs lol do you think she meant anything by it or no ? Just wondering
