'Is this your water bottle?' a voice asks me.

Standing in front of me is an Asian woman in her 40s. Her hair is in a ponytail, she wears glasses and is in leggings and an oversized t-shirt. I thank her.

She tells me her name is Kate. The gym is quiet, it's a Saturday morning. I'm between sets so we sit at a table in the lobby and talk.

I learn Kate is married, a mum of two and teaches highschool. She and her husband emigrated to New Zealand 12 years ago frim China.

Over the next month I bump into Kate at the gym often. We always stop to chat. One Saturday she's with an older Asian guy, grey hair and a little belly. Kate introduces him as her husband Frank. Like Kate, he's friendly and engaging. He asks me if I have plans that evening. I don't so he invites me over for dinner. Kate will cook.

I arrive at 7PM exactly and knock on the door. I get a shock. Kate answers the door. But it's not the Kate I'm used to. This Kate is wearing a wrap dress that shows off her figure. Tight at the hips it flows up to her slender waist. What has got my attention is her cleavage. The tops of her breasts are clearly visible. Kate is wearing her hair down, the glasses are nowhere to be seen. She's wearing perfume and make-up. In short she looks stunning.

What's even more surprising is how Kate greets me. She presses her body against me in a full hug then gently kisses me on the lips. Frank is in the doorway watching. He's seen his wife kiss me and doesn"t look botheted at all. He's smiling broadly.

Dinner is wonderful. Kate is a great cook and the conversation flows. After dessert we're drinking coffee in the livingroom. Kate is on the sofa next to me. Frank is in an easy chair across from us.

He looks at me seriously for a moment and asks, 'Do you think Kate is beautiful?' I say yes because it's true.

Frank nods then says, 'Would you like to fuck her?'

I think I"ve misheard but then feel Kate's hand on my thigh. 'I want to go to bed with you. Right now. And my husband wants to watch.'

Seconds later Kate is in my arms and we're passionately kissing. We make out for about 20 minutes before she leads me by the hand to their bed. I sense Frank behind us.

We kiss and undress each other. I turn Kate around and undo her bra. Her breasts leave me in awe. They're perfect. Large, firm, with a beautiful teardrop shape. I lower my mouth and suckle her breasts. She moans loudly.

I remove her panties, drop to my knees and begin ravishing her pussy with my tongue. After a few minutes Kate starts humping my face, screaming in orgasm. When she recovers she kisses me and then pulls my pants down. She gasps when she sees my cock and immediately takes me in her mouth.

She drags me to the bed. Frank hands me a condom. I put it on, then slowly enter his wife. Kate sighs and then moans as I stretch her. Soon I'm all the way in and we begin moving together. I place Kate's leg on my shoulder and she goes balistic. She begs me to fuck her harder. I place both legs on my shoulders and start pounding her. A string of curse words flow from this proper school teacher including that she loves my white cock. She blurts out that her husband could never fuck her like this.

Soon I'm close to cumming. Kate puls my head down to kiss me and soon my cock twitches then explodes inside her. We hold each other and drift off into space.
