Crossing her legs in a 85 degree hot sauna

We lay in the 85 degree hot sauna
She lay down on her back, pulled her legs towards her and then crossed her lower legs. Then she grabbed her feet with both hands to rock back and forth. As I was lying opposite her, I could clearly see her vagina, which stretched as a long slit down to her anus. There is a direct connection from the anus to the vagina due to a perineal tear during *****birth. As she kept pulling her feet towards her, her vagina moved back and forth in a slow rhythm.

My cock swelled up and I got hard and covered it with the towel. A guy opposite was staring at her pussy but she didn't notice.

We left the sauna and swam in a naked pool. I grabbed her body at the edge of the pool and penetrated her. She responded to me with light rhythmic movements of her hips.
