I'd been seeing an older Japanese woman, Junko, for about two months and all we ever really did was fuck each other senseless. She had a tiny, almost hairless pussy and little tits with nipples that grew about an inch long when they were hard. She also had a kinky side and liked me to slap and choke her as we fucked and she was very much into watching us fuck- she had mirrors all over her bedroom that were positioned exactly so she could see my cock in her from any angle, whether she was sucking me or jerking me off or getting my cock up her little cunt.
The other thing Junko really loved was watching me masturbate. It would start when she picked me up from work. I'd get in her car, unzip my pants and start rubbing and stroking my cock and balls for her. I'd milk a drop of precum out and we would share the taste of it. If she were wearing a skirt, she'd put a finger inside her pussy and we'd share the taste of that too. By the time we got to her place or mine, her pussy would be very, very wet and hot and my cock would be extremely hard and we would fuck madly, always ending with her pulling her hair back and urging me to cum on her face and in her mouth.
One early evening we went to my place. I had something new in mind that I'd always wanted to do with a woman and I had a feeling Junko was just kinky enough to try it. We each took a quick shower and I shaved my cock, balls, and around my asshole. I called her in to the bathroom, showed her my hard, smooth cock, and asked her to feel that it was as smooth as she liked it. She approved of my work and got on the bed and started lazily playing with her clit. I had one more thing to do before we got to it. With my fingers all soaped up, I slid my index finger up my ass. I'd skipped lunch to go to the gym instead and so I was nice and clean inside. I rinsed off, dried off, and joined Junko on the bed, watching her do her clit and occasionally slip a finger into her little pink pussy.
I lay beside her and started slowly jerking off while she watched me, her hands now more rapidly working on her pussy and her nipples at full inch-length hardness.
"I love your cock. I love watching you do this for me," she moaned, spreading her lips to get two fingers inside herself.
"And I love doing it for you," I replied as I turned to give one of her nipples a little bite. I got up on my knees beside her head so that she could lick and suck my balls and asshole while I continued tugging at my cock.
"I want to try something with you. I hope you'll be okay with it," I said.
"I'll do anything you want." Exactly the answer I wanted to hear.
"Please put a finger in your pussy. Get it really wet."
She did as I asked and showed me the slippery wetness.
"Now, take it and slowly put it inside me," I directed as I opened my legs, my cock and balls still hanging beside her head.
"In your bum? Really?" she asked.
"Yes. Please. Are you okay with that?"
"I've been waiting for you to ask! I've wanted to do that since I met you."
