My best friend introduced me to a sex friend - I'm a married woman, but to be honest, my pussy is aching...

"It's not an affair... A sex friend is just someone to satisfy your sexual desires."
He parks his car on a dark street and pulls over to cover me. Before I had time to resist, his tongue pried open my lips and tangled with mine. At the same time, his hands roamed over my breasts, stimulating the sensitive tip.
Ahhh...if I don't do this, I'll be swept away... Even though I knew it in my head, my pussy was tingling with the excitement of being touched by a man for the first time in a long time....
--My husband and I moved from Tokyo to our hometown, yearning for country life. Our friends in our hometown welcomed us with open arms, and today we had a drinking party with my best friend from high school, Yoshimi.
However, when Yoshimi was drunk, she asked vulgar questions like, "Are you having sex with your husband?
When I confessed that I didn't, she said something like, "Okay, I'll introduce you to my sex friend." I thought she was joking, but she really brought a man with her! And he looked so familiar...
Is the countryside such a sexually promiscuous place?
