I discovered my father was having an affair, not only that, I discovered who she was, where she lived and her telephone number. When my mother found incriminating evidence in Dad’s suit pocket I managed to convince her that Fiona was my lover. There was a price for this which my father had to pay; fucking his mistress and his daughter. The Rubicon crossed I know he will want more and that I certainly did.

For now, his mistress is enjoying my young flesh and I’m about to enjoy hers.

* * * *

Fiona’s tongue opened my lips probing into my vagina to let out my father’s cum still trapped in my body; I heard her slurp and swallow my juices and his semen. Before me his mistress, her legs open waiting for me to reciprocate the love; I was about to demonstrate my bisexual nature; taking a deep breath I took the plunge.

I had licked my own juices from my fingers many times, closing my eyes to make believe they were some other girl’s. Now Fiona’s pussy lips were inches below me; smoothly shaven, bulging slightly around the clitoris they guarded. The smell of sex wafted into my nostrils; gently, I opened her lips to expose more of her jewel.

My tongue slithered over her clitoris and probed the opening below it; she was wet and sticky and tasted so much better that I do. Fiona moaned into my pussy, I was desperate to feel her cum so closing my mouth around her clit I sucked on it, the hard nub engorging in my mouth. I locked my lips around it worked it like a miniature penis, driving my tongue into the end.

Beneath me her body tensed and her fingernails dug into my buttocks; her mouth released my own pussy and Fiona gasped for air. I strayed from her clit for a moment to lap up the wetness flowing from her, it filled my mouth with a sweet sticky nectar; I wanted more and making her cum I would get it. Again my lips closed around her clit and I sucked harder and harder, jabbing the little button with my tongue. She moaned and was still. I liked and kissed her open pussy until I brought every drop of her cum to my mouth and swallowed it. I rolled from her smiling to myself; I’d brought another girl to orgasm.

We lay side by side for a while until I went to the bathroom to freshen up. Beside me a wicked laundry basket caught my attention, curios about my new lover I opened it. This woman wore some very sexy underwear. I looked up to find Fiona standing in the doorway.

“If you’re looking for the pair I was wearing when I last fucked you’re Dad it’s the red thong.” She reached past me, pulling them from the basket she handed them to me. The crutch was hard and stained with the goo from their sex.

“Put them on.” She told me. “Then, I was wearing the matching bra and suspender belt.”

Fiona began to dress me, the bra, thong, suspenders and stockings she had been wearing; then found a skirt and a blouse. I felt so sexy, then as she put a dab of the scent Dad had bought her behind my ears and on my wrists. In a moment she had made me Fiona.

She led me back to the bedroom; pushing me against the bed she knelt before me. “Fiona darling,” she whispered, “You are so sexy, I want you and I’m going to fuck you hard.”

In an instant I understood the game, “You can do whatever you want to me James.”

I closed my eyes and imagined the soft hands climbing up my thighs were my father’s. My skirt was being lifted and I was pulled towards a wanton mouth. My proxy father’s breath was hot on my pussy. Lips kissed the gossamer material covering my slit, my own wetness now adding to the stain on the thong.

“You taste so sweet Fie.”

“Do I James? Enjoy my sweet pussy then, take what you want from it.”

 I was gently turned around to face the bed, as she pushed me over the edge of her very high bed; my hips fitted comfortably across the corner of the mattress and my feet just touched the floor. A tongue explore my pussy, opening my labia and delving deep into it; the tongue moved up alone the crack of my arse and found my anus, swirled around it for a moment then forced its way in. I groaned with surprise and joy.

 “I know you love that Fie, but we aren’t going to play with that hole tonight.” This was not just role play, I was being schooled in my father’s sexual preferences, the thought of my father’s big cock pushing its way into that tight hole made me shudder with anticipation.

Behind me something nudging against my pussy; soft hands stroked my back and worked their way down the sides of my body until they reached my hips; then gripping them my lover thrust forward. My pussy lips were prised open and I felt a cock boring into me. My surrogate James had endowed herself with a penis and started to give me the hard fucking I had been promised.

“Yes James please, push all your length into me, fuck me Darling, fuck me as hard as you want,” I moaned.

The latex shaft plunged deep into me, deeper than any boyfriend, deeper even that my Daddy had pushed a few hours before.

“God Fie, you’re so tight and wet Honey, I want to feel you cum.” A hand slipped down across my tummy and into my crotch; then a finger ran between my lips searching out my clitoris and rubbed it. My body responded in an instant, the boiling feeling in my vagina, the tingle along my spine. I heard the wet sloshing of my sodden crouch and felt my own juices cooling as it running down the inside of my thigh. I was close to orgasm. A sudden hard slap on my buttocks caught me by surprise; the sharp stinging pain ricocheted though my lower body hastening my orgasm and left me screaming into the bed sheets. I lay bent in half quivering; the plastic cock pulled from me leaving a void within me.

There was relief for a moment as a tongue licked my sore pussy clean, but again the plastic shaft was driven far into me forcing me hard against the bed. I clawed at the sheets as the dick was thrust into me. It felt so lifelike, but no boy had ever been able to fuck me for so long. I lay hoping my James would not tire before I came again.

Then a thumb invaded my tighter hole; unannounced and uninvited, it pushed though my anus and into the cavity behind. Cock and thumb worked in unison, my body ceased to be able to separate the sensations and it felt that the whole of my body was being fucked. I came again this time harder and deeper.

I lay motionless, exhausted and let my lover slow the pace and finally stop. Cock and thumb withdrew and left me to rest.

After a while I felt catch and zip of the skirt being undone, then it was slipped down my legs and onto the floor; the thong joined it. I was pulled upright into my lover’s arms; the latex cock hard and threatening between my stinging buttocks. Nimble fingers unbuttoned my blouse and pulled it from my shoulders, then my bra unclasped push away from me.

 I was gently turned to face my lover, she was Fiona again and I Gemma. She pushed me back onto the bed. I climbed up and lay back with my head on a pillow. Fiona crawled towards, the latex shaft swaying menacingly between her legs. My feet moved apart to accommodate her and she pushed the prick into my sore pussy again.

 There was no hard fucking this time, Fiona laid on me, our lips found any part of each other’s body they could. Mouths and tongues kissed, licked; hands explored, fingers caressed, breasts and hips rubbed together. The suspender belt and stockings felt alien to me making my mind focus around my thighs and hips; all this time the cock inside me was being twisted this way and that as we writhed together. Gently an orgasm built in me and gently I let myself cum. Fiona felt it too, sliding down my body she let the cock slip out and I rested at last. 

I was sated but my lover had yet to cum, she pressed a hidden button on the device and it started to vibrate. Kneeing beside me she forced the toy into her own body holding it with both hands, twisting it inside her until she found the spot that would relieve her frustrations. Fiona closed her eyes and grunted then slumped beside me, the tool still humming as it slipped from her body.

It was morning when I woke, soft sheets and a soft body were the first sensations of my day. I kissed and hugged my lover until she pulled from my arms and left our love nest. I watched her perfect body cross the bedroom and out of the door then closed my eyes.

A voice summoned me from my sleep; Fiona stood in the door way, my jeans were loose around her tummy and hung off her hips exposing the top of the plain white knickers I had arrived in yesterday. Under my tee shirt her breasts, a cup size larger than mine, spilled out of my bra. She worn no makeup and looked about nineteen or twenty at the most.

“Hello sleepy head, do you want to fuck a virgin teenager?” I certainly did.

 Grabbing some clothes and things I made for the bathroom: if I was going to play the part of the guy that took me for the first time it would be in character. This time Gemma would lose her virginity with a little more consideration.

I clipped the harness of the Strap-0n around me and pulled my spare jeans up; then tucked the dildo down the front so it looked like a bulging cock. On went the tee shirt and I was Gary about to break his way through another hymen.

Fiona was still waiting as I sat back on the edge of the bed.

“So Gemma, come and sit here.” I patted the bed beside me.

“I don’t know…” She needed a name.

“Gary,” I said softly.

“I don’t know whether I should Gary.” Fiona’s mood had changed she seemed nervous.

“Listen Babe, Mom and Dad are going to be out all day, so we have plenty of time to ourselves.”

I took her by the hand and coaxed her onto the bed.

“So Babe is this when we finally get to be lovers?”

“I guess so,” she mumbled. “Are you sure your folks aren’t going to come back early and catch us?”

“No chance Babe, like I said they are out all day.” I let my fingers slide over her neck and shoulders, then down over her breast.

“It will be OK Babe, you will feel so good afterwards, so grown up, so much more like the woman you are.”

Her fingertips followed the line of the dildo stretching the denim of my jeans.

“It’s very big Gary, I’m not sure I can take it.” Her voice was thin and awkward.

 “It will Babe, we both did the same human biology lessons, that’s where it’s designed to go. We will take it easy, you will be fine.” By now I was rubbing her nipple, her breath was heavy. I brought her up into a sitting position for a moment and lifted off her tee shirt; kissing her neck while I freed the bra strap. She sighed deeply as I laid her back onto the bed.

I let my tongue snake its way down her stomach until I found the stud on her jeans; a twist of my fingers and it was open. With the zip pull between my teeth I moved south opening her jeans to expose the white knickers below. She lifted her hips and pushed them both away; her naked body now exposed to my gaze.

I lay beside her again and unzipped my jeans; the bulbous end of the latex cock sprung free. My Gemma shied away a little.

“It’s OK babe, you have seen it before, and you’ve held it, even helped to make it cum. We will take it easy Babe; it will be good for you.”

I shed my cloths and locked the dildo into the harness. Gently I parted her legs and stared into her face. My Gemma’s eyes look right through me; she was in a different time and space.

The latex cock nestled against her vagina; I pushed up gently, there was no physical barrier, but she winced as if a mental one was broken. I started slowly with rhythmic thrusts, gradually getting deeper, quicker and harder.

Her naked body looked young and somehow virginal beneath me. Although this plastic cock between my legs gave me no sensation of feeling, I still felt like a boy, in control of the depth and tempo of our lovemaking.

Suddenly she grabbed me, almost tearing the skin from my body.

“I’m cuming Gary, I’m cuming, please, please don’t stop,” her voice still young and reed like. I kept my pace, thrusting the latex tool in and out of her body until she shuddered and shook beneath me and an orgasm took possession of her. In that moment a wave of pure energy broke over my body like a tsunami and left me as satisfied and drained as she was.

I slid down the bed, my surrogate penis slipping from her; I unclasped the harness. Then lay with her again as a girl. We kiss and looking into each other’s eyes.

“Are you OK?” I asked.

She nodded, “I am now.” We kissed again, gentle and loving.

Suddenly I realised that something had changed in her and in me; I was in love with my father’s mistress and she with me.

How would that pan out when we fucked him together again?
