36 (M4A) Oregon/Online. Me and my new gf (33F) had sex last night while she wore my daghters clothes and need help processing it

Basically me and my gf were messing around doing laundry when she jokingly tried to see if she could fit in my girls clothes, took her a minute but once she got them on, just shorts and a tshirt, we immediately gave each other the look and started going at it. It was some of the hottest sex we've ever had. Felt a little bad about her age but not like she was there and definitely want to explore it further but need someone to talk to about it because obviously can’t with friends and such haha
