She [F] anally fingered me [M] and I loved it

My partner is super-hot. She is tall, thin and muscular. She has long legs, a nice ass with wide hips that leave her with just the smallest thigh gap. Her stomach is flat and her waist is small. One of the sexiest things about her is that she does not seem to know how hot she is. All her girlfriends are jealous of her body, she is without a doubt the hot friend in the group and I catch all the husbands looking at her. She is a teacher and very wholesome and reserved sexually. Although we have been together for several years now, I found out not long ago that she enjoys some playful choking during sex. Discovering that she has some hidden kinks has got me excited to explore what else might be hiding behind her wholesome, reserved exterior.

The other night we were in bed, she was playing with my cock and I was grouping and kissing her. She ran two of her fingers down and under my balls, circling my asshole with them. It felt great and I pushed my hips up and opened my legs so she would know I was wanting more. She took the hint and pushed gently against my asshole. I groaned a little and said “put your finger in”. She did and it was pretty uncomfortable… I asked her to wait while I got some lube out.
