Now that Emma and I had given into temptation and spent the night fucking incestuously in my flat things got progressively more and more perverted. It seems my beautiful 19 year old sister was kinkier than I thought was possible and even though I was 40 and supposedly worldly wise I had a lot to learn from Emma.
For the first few nights following our leap into the depraved world of incest I would leave my business at 7pm and return to the flat to be greeted by a naked Emma. She would have a bath drawn for me and then she would undress me and bathe me as tenderly and proficiently as any Japanese Geisha. The bathroom was illuminated by scores of candles, the water was steaming hot and Emma made sure that we had glasses of chilled white wine to ease the tension away.
After Emma bathed me I would invariably be rock hard and lusting after her tight, lithe, golden body. She would lead me from the bathroom back to the double bed that we now shared and once there Emma would lie back on the bed, spread her legs and invite me to taste her smooth lipped cunt.
After I had given my sister her first orgasm she would then suck my thick cock until I was on the verge of exploding into her warm mouth, stopping moments before I hit the point of no return. She would let me cool down a little before sucking me a little more and once again stopping just as I was about to shoot. Emma would keep me on the boil for hours in this vein and the exquisite torture drove me insane with wanting her. I would try to force her to fuck but Emma would dance away from my grasping fingers and tell me to be patient.
This little trick of hers worked however because when I finally did come I found that I was able to maintain an erection and therefore prolong the pleasure for both of us. I revelled at the sight of Emma taking the first spurt in her mouth and then taking the rest of my load on her face and tits. Then, with my spunk dripping thickly from her body and face, Emma would offer her pussy to me to fuck. I loved taking my sister from behind and I would fuck her and massage my cum into her firm breasts as I did so.
This scene was repeated with a few variations, during the early part of our relationship.
It wasn't long before Emma introduced me to something new.
I arrived home as normal and instead of Emma greeting me nakedly as I had become accustomed to she was dressed in a tiny mini skirt and high shoes with a tiny scrap of material that was pretending to be a top barely covering her cute bosom. When I asked what she had in mind for the evening Emma merely smirked and told me she had a surprise in store for me.
I showered and changed into some casual clothes as Emma had told me to do. I made my way back into the living room once I'd dressed and was surprised to see a woman sat on the sofa chatting to my sister.
Emma stood and introduced the woman to me, her name was Erika and she shook my hand and spoke to me in a German accent as she smiled in greeting.
Erika was a mature woman in her early forties. She was very well maintained however her body looked impressive to my roving eyes. Erika was wearing a black dress that hugged her figure and showed off her ample breasts and jutting nipples. She was wearing black stockings and high heeled shoes and her legs were very shapely and well proportioned. Her skin was tanned and her hair was a tinted red colour that really complimented her skin tone.
Was this my surprise?
Emma told me to get a beer from the fridge, sit in the armchair and to just watch without saying or doing anything.
I did as I was told and silently stared as the two women began to kiss lightly and feel each other's bodies through their clothing. Things progressed fairly quickly and soon the mature Erika and my sister were kissing each other more passionately, their tongues intertwining in a wet dance with Erika pushing my sister's tiny vest top up to reveal her firm teenage breasts.
