Her name was Katrina. We met a year ago at my doctor’s office when I went for my annual physical.

I had been seeing the same doctor for years and was familiar with his staff, but when Katrina greeted me in the reception area it was a pleasant surprise. She was about 40 years old, had a voluptuous figure, and an inviting twinkle in her eyes. I have been married for more than 20 years, and my husband, Paul, and I have an open marriage.

We have tasted almost the entire repertoire of sexual pleasures, including threesomes with both men and women, and spouse swapping. Occasionally I have engaged in woman-on-woman encounters, sometimes alone or with my husband watching and participating. Since I am a very erotic being and open up quickly to sexual overtures, something about Nurse Katrina struck a carnal nerve in me.

In the examination room, she asked me some general questions about my health and did her examining most delicately. She touched me softly — just slightly more than was necessary. While I disrobed, she eagerly helped me and complimented me on my perfect body. More than once her soft fingers touched my skin. When the doctor walked in, Katrina stayed in the room and watched the entire time as he did his examination. On my way out, I scribbled my telephone number on a piece of paper and handed it to her.

Katrina called me that evening, and we had a long conversation about our sexual life-styles. She’d been married for a few years, and divorced after she discovered her interest in women. Paul overheard our conversation and demonstratively licked his lips. I invited Katrina to our house the next day. Physically we hit it off right away. We embraced and kissed. Her full lips felt soft and velvety. We looked at each other and laughed and kissed again. This time she gently opened her mouth and cupped my lips. The tip of her tongue lightly brushed back and forth. Soon we were French-kissing and exploring each other’s mouth with slow, loving strokes.

The lower part of my body turned into quivering jelly as my pussy heated up and became increasingly wet. Katrina’s hands explored my back and finally seized my butt cheeks, pulling my pelvis into hers. I gently disengaged myself and asked, “Bedroom?” Katrina nodded and followed me down the hallway. Sitting on the king-size bed, we undressed each other, kissing and fondling along the way. Her luscious breasts were white as snow, with light-brown large, firm nipples. I lowered my head to lick and suck them.

“Suck hard,” she moaned. With one hand she kneaded my own globes and with the other she searched between my legs. When I spread my thighs to give her access, my slit was already very wet and open. I felt the cool air and then the touch of her finger. She lightly rubbed the outer lips, sending shivers of delight through my body. With her wet finger she stroked lower over the bridge between my vagina and anus and back across the pouting lips. Then further down, she finger-rimmed my puckered ass hole. I was hot and ready to explode into nirvana. Her tongue was still deeply exploring my mouth when suddenly she inserted two fingers into my cunt and with her thumb on my clit pushed me over the edge into another world. I came in waves of delicious emotions.

Wanting to repay Katrina’s sweetness, I pushed her onto her back on the bed, kneeled down, and started to caress her thighs with my hands and tongue, licking my way up to the central part of her sex. With broad strokes I lapped up her flowing juices, eliciting a sigh every time I touched her clit. Then she pulled her legs up into the air, spread them open, and wiggled her body up and down, meeting my tongue thrusts. I increased the pressure until finally she let out a long, hoarse wail. We embraced and relaxed. While she caressed me, I asked if she would stay until evening and meet Paul. Mischievously she asked, “For an encore?”

She helped me cook dinner and was the most gracious guest ever to dine at our table. Paul was enamored of her; I could see the lust in his eyes. After the meal we agreed to “play.” What a show Katrina and I put on for Paul. When at last we engaged in a hot sixty-nine, Paul could wait no longer. He maneuvered himself into position and entered me from behind while Katrina was still licking my pussy and clitoris. With firm, steady strokes he fucked me until we both climaxed with joyous cries. Katrina, we found, was not completely averse to men. She let Paul fuck her repeatedly. It was a night full of ecstatic sex all around. Since that day, Katrina has become our frequent bedroom partner and companion.
