Next day, her frostiness had gone, and I decided to leave matters until the weekend when her father and mother were due to spend Saturday evening with us and stay overnight. I thought to myself that if I couldn't get to Conchita, then maybe I could get to her father.
Conchita spent most of Saturday afternoon preparing dinner and cleaning the house in readiness for her parents. They usually came for dinner once a month, and though they only lived about five miles away, it was easier for them to stay over and enjoy a drink than to drive home and have to remain sober.
Her parents arrived at about six o'clock and I went to meet them at their car and carried their overnight bags into the spare bedroom whilst Conchita made them something to drink. I put her father's bag on the side I knew he slept and made sure he could see what I had planted earlier. A few years ago I took some photos of Conchita. They were not dirty pictures, just shots of her in some sexy dresses, lingerie, and bikinis. I used to like to look at them myself whenever I wanted to masturbate. Earlier that morning, I had placed three of these photographs in between some books that lay flat on the second shelf of the bedside table that would be closest to Conchita's father. One of them showed her posing in the bedroom wearing a white bikini and sling backs, another in a mini dress and high heeled pumps and in the third, she was standing against the bedroom wall in a black teddy, stockings and high heeled sandals. I positioned this last one so that her legs were visible up to mid thigh and hoped that it might tempt her father to look more closely. I would be able to tell by their position next morning whether he had looked at them or not.
At about seven o'clock, Conchita excused herself to have a shower and change for dinner, leaving me to entertain her parents. We had a couple more drinks, talked about our jobs, our houses, the family. By the time Conchita's footsteps were heard coming down the stairs forty minutes later, we were all pretty much on the way to being merry. The living room door opened slowly as Conchita came in. I sat on a chair talking to her mother, who didn't take much notice of her daughter's entrance, and had a good view of her father sitting next to his wife on our long couch. From the corner of my eye I could see that Conchita looked stunning. She wore a short, skin tight red dress and black, four inch heeled pumps. Her naturally olive skin seemed to glow. And all the time that he thought no one was looking, I caught sight of Conchita's father eyeing her with that same look of desire that I had seen many times. During the course of the evening, as Conchita moved around us, clearing plates, serving food, or picking up empty wine glasses from the floor, her father must have realised the same thing that I had; That the only way his daughter could possibly have worn such a clinging dress, was by not wearing any underwear. I wondered if that thought made him feel as horny about her as I did.
At around eleven o'clock, Conchita's mother had done her usual trick and passed out. Her father dragged her upstairs, apologising for his wife's behaviour, leaving Conchita and I alone to clear up. As soon as they had disappeared from sight, I told Conchita that she looked fantastic and asked her if she had noticed how her father had been secretly eyeing her up all evening. She told me that it was all in my imagination. I explained that I knew the look of desire on a man's face when I see it and I told her it would be very easy to get him to make a pass at her. Conchita said no way. But, I thought, with less conviction than when I had first raised the possibility.
I followed Conchita up to our bedroom, admiring her ass as it wiggled in front of me. I could hear no noise from her father and mother in the bedroom next door and wondered if he was even now, looking at the photos of his daughter that I had left for him. That thought, and Conchita removing her dress to show that I had been correct about her lack of underwear, both served to make me feel very horny indeed. Normally when her mother and father stay over, Conchita and I do not make love. She has a tendency to be noisy during sex, and combined with the squeaking bed springs, says she would feel uncomfortable the next morning. But that night, I wanted her father to hear his daughter's cries of pleasure as I fucked her to orgasm, and have him wish that he was in my place.
So, against her protestations, I started to bang away at my wife. I knew that her mother would be out for the night and that her father would be the only one to hear our love making. I performed at my best that night, spurred on by the thought of our audience on the other side of the wall. Conchita was taken to such a height of ecstasy that she could not prevent the loud moans and yelps as I brought her to a climax. Just before she reached that crescendo, I lowered my lips to her ear and whispered:
'Imagine this was your father on top of you now and not me. Wouldn't it be exciting to be fucked by him, baby? Imagine the thrill of doing something so wrong. Imagine your husband watching you being used like a sex object by your own father.'
Conchita said nothing in reply, but as I spoke these things, I noticed that her breathing increased rapidly. And by the time I had finished my last word, she was in the throes of climax. As Conchita recovered from her orgasm, I asked her if she would consider my proposition if I could prove to her beyond all doubt that her father was lusting after his daughter. She lay quiet for a long time before finally giving me an answer:
'Perhaps.'
Next morning at breakfast, I tried to see if I could detect a look of envy in Conchita's father's expression. But he was too busy nursing his wife's hangover to show any other reaction. It was for this reason that they left before eating anything. As they drove off, I was desperate to see if the photos I had left in his room had been moved, indicating that my father in law had looked at them. Conchita asked where I was off to in such a hurry, but I remained silent. I dashed into the bedroom her parents had occupied and walked quickly over to the bedside table where I had placed the pictures. I knew that a simple re-positioning of them would hardly constitute the proof that my wife needed, but at least it would prove it to me, and that would carry me on to more devious methods.
As I approached the bedside table, I could see that Conchita's father had indeed looked at the photos of his daughter, because the legs that I had left visibly sticking out between the books were not there. He must have put them well out of sight after he had examined them, maybe even masturbated over them whilst Conchita's mother had been in the bathroom. I bent down to find and remove them, but even after looking through all of the books on the table I could not find the pictures anywhere. It finally dawned upon me that he had taken them with him. My head felt very light as the realisation that I had been right all along hit me. This was the proof I needed to convince Conchita that her father really was sexually interested in her. I ran downstairs and into the kitchen where Conchita was having some breakfast. I had a big grin on my face and she asked me why I was so happy. I told my wife what I had just found, or rather, hadn't found, in the bedroom used by her father. I went through all the evidence that I had. Then, with a lump in my throat, I asked her if I could go ahead with my plans for her seduction by her father. Conchita was silent for a moment, deep in thought. It felt like a lifetime before she finally spoke;
'Do what you have to', she said. Her voice was less enthusiastic than I had hoped, but at least I had gotten her to agree to it. I could hardly believe it; she really had just agreed to having sex with her father. Now I could put my plan into action.
I had to wait until her parents came to stay with us the following month. The Saturday evening went like all the others. Conchita's mother collapsed under the excess of alcohol and was taken to bed by her father. That night I was even more horny than usual. I explained to Conchita that I wanted her to be as noisy as possible during our love making. I told her that I would be having sex with her three times before we got up on Sunday morning. She looked quizzically at me but I just said that it was essential to my plan.
I fucked Conchita as soon as we went to bed, again at around three in the morning, and once more just as the sun came up. She was as loud as I had wanted her to be, and there was no way that her father in the room next door wouldn't have heard us.
