I lunged forward and she screamed, I gripped her hips and held her tightly as my juices boiled, I was as still as a rock for a very few seconds, then I let out an involuntary grunt and my prick exploded, I still didn't move, every sense, every nerve in my body was centered on my prick as it spewed it's load into her tight, clutching anus!
The following day was beautiful, the sun woke us up blazing in through the open bedroom window, we ate a leisurely breakfast and read the papers in the sunshine before going to play tennis.
She looked gorgeous in a minuscule white skirt barely long enough to cover her lovely little bottom and a push up bra under a tight, white tee shirt was more than enough to grab my attention.
She took full advantage of it and trounced me thoroughly, I laughingly accused her of cheating by bending down or making her skirt flare up at every opportunity.
"I happen to be very athletic" she laughed, "I like bending and stretching"
"I like it too Patricia" I laughed, "Especially when you dress so provocatively, but can we get back to your many little kinks?"
"Let's have an orange juice on the patio" she suggested and ran up the half dozen steps from the tennis court ahead of me giving me a cock stirring glimpse of a narrow white string between her cheeks.
She made me sit on a chair away from the table and sat on my lap facing me with her arms around my neck,
"This is one of them" she smiled with her lips only millimeters from mine, "Sitting on the bosses knee"
I felt a the warmth of her cunt on my groin and as her mouth descended on mine, she added,
"With wet panties and knowing that he's about to fuck me"
My prick rose immediately as her tongue slipped between my teeth, her breath was warm and we breathed the same air, our tongues dueled with each others as she writhed against my fully erect prick, easing herself up slightly she quickly unfastened my shorts and eased her sodden gusset to one side.
"I think your prick enjoyed that" she giggled as it slid home, "But did you like my little kink?"
"What do you think?" I growled and lunged upwards bringing a squeal from her beautiful mouth,
"God almighty" she gasped, "No wonder your wife's staying longer, I bet you wear her out when she's here"
"No I think she's got a lover over there"
"Oh I'm sorry"
"Don't be, I'll be relieved if she leaves me"
"Oh?"
"Because that means you can move in with me if you like"
"Only if you promise to fuck me every day like this"
She rolled her hips and I felt her vaginal muscles squeezing me,
"God, you've got a deal, one fuck a day and two at weekends"
I fucked her slowly with long deep strokes, each forward thrust bringing a moan of pleasure from her beautiful mouth, her hands gripped my hips, her nails digging into the flesh but the pain only spurred me on, that and the delicious little obscenities she whispered into my ear.
"I've got a friend you should meet" she whispered although I wasn't really interested in meeting anyone at that moment, the tingling in my toes was beginning and I knew the end was nigh, but then she added sexily,
"She loves to be fucked while eating pussy"
"Really?"
"My pussy in particular"
"That sounds rather fun" I said and felt my penis swelling even more,
"Yes" she said as the feeling started to overwhelm us both, "She's my sister" and the dam broke leaving us wallowing in the waves of ecstasy!
