Assfucking while she’s still wearing her thong makes her more horny, simply because her pussy stays covered.
She always wears thongs so not long ago she was sucking my cock really well and then wanted to fuck me cowgirl. Her thong was still on, so I pulled the ass-string aside as shoved my cock up her asshole. She really loved the extra sentation of feeling the fabric rub on her clit while she rode my cock. It felt better then with no thong.
Few days later we did it again with her thong on, but this time I fucked her doggy and missionairy. She told me afterwards she felt more sexy because her pussy was covered before my eyes. She really enjoyed that all attention went to her asshole and her pussy got forgotten.
This is a great new development which needs to be further explored.
