Here is how Toshiko and I discovered our enthusiasm for masturbation as a cornerstone of our sex lives.
Early in my time in Japan, I lived in a small (and I mean small) apartment. My neighbor was a Japanese airline stewardess. I never got to know her, we just exchanged the occasional "konnichi-wa"? - but I did quietly lust after her, and would sometimes develop a raging hard-on having watched her walk into the building in her prim uniform with its short skirt over black pantyhose. She worked for All Nippon Airways, so I thought of her as "Ana"?.
Toshiko was round at my place one evening, and we were having our dinner seated on the floor, the only place to sit in this apartment while watching TV, when through the very thin walls we started to hear Ana? moaning quietly. At first, Toshi and I each pretended not to notice, but the fiction became harder to maintain, and I turned down the sound on the TV. I developed a major hard-on, imagining Ana? with her hands working away inside those black pantyhose. Toshi began to blush and squirm slightly. Eventually, she said quietly something like, listen, sounds nice?.
My neighbor gradually picked up the pace. Toshi was wearing a skirt over black pantyhose, not unlike my neighbor's, I reflected, and as her hand moved to her upper leg, she gave me an "is it OK?"? sort of face. I nodded, and she slid her hand up her thigh to her crotch and began rubbing slowly as we both strained to hear what was going on on the other side of the wall. I imagined I unzipped my pants and joined in the action.
Our neighbor suddenly cranked up the volume, culminating in a delightfully audible orgasm. Too much for Toshi, who lifted up her skirt, lay back, slipped her hand inside her pantyhose and panties, and began rubbing frantically. I removed my pants, and, as I stared at Toshi's hand moving, I got myself out and went at it quickly too. Neither of us took long to come, and I think we must have given "Ana"? something to listen to, returning her gift to us.
Those few wonderful minutes were the start of some great times for the two of us, as you can read elsewhere!
