Yes. I have seen it before my marriage. A few weeks before my marriage I was studying in college staying in a hostel. My marriage was arranged immediately after the completion of three years of study. As my groom is a resident of Canada and his India Visiting Visa is expiring soon, the marriage arrangements were fast-tracked to complete the marriage immediately and take me to Canada with him. Ours is a love marriage.
And so I finished my studies and came home just two weeks before my marriage. My house is a modest house with only two bedrooms. My dad is a businessman. He goes out during the day and comes home only to eat and sleep at night. My mom is a housewife. She spends her time doing housework and fulfilling chores for her husband. They are also married for love. When I came home I found my bedroom was being used as their bedroom. My younger brother had also gone to college at that time. So they gave me his bedroom for the two weeks I was going to be there before my marriage. It was right next to my bedroom. I had a bit of travel tiredness so I ate and went to bed early. In the middle of the night, I felt thirsty. I went outside of my room to drink water.
Then I heard someone moaning and panting inside my old bedroom. When I put my ear to the door and listened carefully, it was my mom's voice. Seeing that the window of the adjoining room was not locked, I opened it slightly and looked inside. Then there was my dad and mom giving meaning to their husband-wife relationship on the bed. Both of them were fully naked hugging each other. Dad was rude to mom. But, my mom was enjoying the pleasure without stopping my dad at all. When I saw my mother, the saffron on her forehead was erased, her hair was interlaced, her eyes were sunken, and she looked like she was intoxicated addiction. But at that time her face was brighter than before. I thought I had come at the wrong time and went to close the window. Then the scene was so good that I kept watching what was going on inside. They were minding their own business, thinking no one was watching them.
After a while, dad got up and left mom and then mom got up and took dad's cock in her mouth and started sucking it. It was like a general coloured stick about seven inches in length. Both the testicles below his cock were enlarged. Mom tasted his dick thoroughly in her mouth while occasionally jerking it with her hand. Dad held mom's head with both his hands to facilitate it. After a few minutes of blowjob, mom turned to the Doggystyle position in front of dad and showed her behind. Then mom's two breasts were hanging well, both her butts were pinkish red and swollen, and her pussy hole between them was round wide and moist. Dad bent down and started licking mom's pussy and stimulating her clit with his tongue. Mom moaned accordingly and started enjoying herself. Dad was passionately tasting mom's pussy while he was jerking his cock with his hand. At one point, when mom started screaming, dad stopped licking her and thrust his penis into mom's pussy and started intercourse. It was a sight to behold for me.
Dad holding mom's waist with both hands and fucking her, mom slowly went to heaven. Her moans became louder than before. Dad spanked mom's butts from time to time and had a hard fuck with her. When I saw the beauty of my dad's cock going inside my mom's pussy, I was in awe. When my mom started screaming loudly, 'Hey! Don't make too much noise. Just control yourself. It's okay if it's like before. Today she sleeps in the next room. If she hears our noise, we will be embarrassed. So make your noise a little.' dad said to mom. 'What do I do? No matter how hard I try, I can't. You have to slow down when you say so much. What if you made it fast and asked me to make noise little? She is getting married in two weeks. After her marriage, will not she also going to be with her husband like we are doing now? So what if she heard the noise we are making now? What if she doesn't hear? If she asks me something like that, I will answer her in the morning. So don't spoil my erotic mood by talking unnecessarily and keep doing the same as you are doing now. Sss.. ah.. ah.. (moaning)' she replied.
'Okay. Your choice. Are you in a high erotic mood today? Do you like what I'm doing to you?' Dad asked, 'How can I not like it when you do it to me? Not only that. You have tied a thaali (Tamil marriage bride’s nuptial thread) around my neck. If not for me, at least for the sake of this thaali that you tied around my neck, whenever you call me, it is my duty to have sex with you as your wife. I am here to give you pleasure. What is there separate in this that is my choice? I like whatever you do for me. Now, this too. I feel like I want to cum. Let's fuck me harder.' she said and started screaming loudly again. No matter what happened, dad started thrusting his cock hard inside mom. The bed was also shaking at such speed.
After about five minutes both started screaming loudly. Dad's speed increased and at one point mom's body started shaking rapidly (I confirmed they both were reached their orgasms). Dad thrusts his cock in a few times and then pulls it away from mom. As mom's body tremors gradually subsided, I could see thick white cum oozing out of her cunt that had been ejaculated by dad. Mom lay back on the bed and took the sperm out with her finger for the taste. Dad was also a bit tired. But the eyes of both were fulfilled with the satisfaction of having accomplished something great. Dad also went to mom's side and mom got up to lie down and licked dad's cock with her mouth and cleaned it well. Later, both of them hugged each other and fell asleep naked. It will be exactly three o'clock then. Already been more than thirty minutes.
I slowly closed the window and entered my room. I was not watched sex for the first time and felt like an electric shock went through my body. When I went into the bathroom and saw my panty it was still wet. After peeing immediately and taking a good shower I lay down again and fell asleep. But the scene kept running through my mind from time to time. I didn't ask them anything. I knew they would be unnecessarily embarrassed if I asked. They have done nothing wrong. As a husband and wife, they satisfied their basic lust in the right way. What right do I have to ask that? Really the fault lies with me. I watched them have sex at least three or four nights a week. After my marriage, my husband fed me all the lust I had developed. My husband had sex with me like my dad had sex with my mom. He is still with me like that.
