The situation we were in was not ideal, but we are family and I will do anything for my family. What I'm talking about is how my sister and her husband had to move in with my wife and I. Covid really put a toll on them, and their finances. They are both massage therapists and used to operate an at home massage and spa. They were actually doing really well for themselves and had quite the clientele. That is, until Covid hit.
Things have been actually pretty nice with them in the house. I get an extra hand with all the outdoor chores, and heavy lifting, and my wife has someone she can constantly talk to and gossip with. My wife Alice stays at home as we are lucky enough to be successful on a one income house. My sister Emily and her husband Tyler were able to set up their massage room in a spare bedroom that we were currently not using. We did not mind letting them do this so they could maintain an income and keep their head above water.
Alice and I are very sexual people and we maintain a very active sex life. We are used to having the freedom to explore each other at all times of the day and night. We hardly ever confine our encounters to the bedroom. Having family in the house constantly has somewhat frustrated us, my wife especially. Alice is just not comfortable with sneaking off in the middle of the afternoon. We have lost any spontaneity in our sex life. Lets just say that has left us pretty unsatisfied and extremely horny all the time.
I can't say the same for Emily and Tyler. Those two are always grabbing and flirting with each other out in the open. I think it is nice that they feel as comfortable as they do in our home. I wouldn't want them to think they are putting us out too much.
One day I arrived home from work. Alice was out taking care of some errands. I walked into the kitchen to find Emily and Tyler in a very intimate situation. The two did not notice me at first, and I remained quiet because I did not want to startle them. Emily was sitting on the kitchen counter with her legs wrapped around her husband. I could tell his jeans were unbuttoned and pulled down slightly. Emily was wearing a loose fitting skirt that had slid almost entirely up her body leaving most of her ass cheek exposed. Her back was arched with her head tilted back. I took in the site completely unsure of what I should do next. I couldn't remember the last time Alice and I were able to enjoy each other so freely. I felt pretty envious of the two.
I noticed Tyler thrusting into my sister, and her readjusting her legs to clamp down on his body even tighter. I was immediately overwhelmed with arousal. In the moment, I took out the fact that I was watching my sister have sex, and just enjoyed the view. I could feel my cock begin to grow. I adjusted myself as the bulge in my pants was growing uncomfortable. This is when Emily noticed me. We locked eyes, but she had no apparent reaction. Emily pulled Tyler closer, and positioned her head over his shoulder. We maintained our eye contact as Tyler thrust deeper and harder. I felt like a statue. I could not move. Emily seemed to find enjoyment with me watching. She gave me a slight smile and then closed her eyes. They both began to moan with pleasure, and I realized that they were beginning to orgasm. I needed to get out of there before Tyler realized I was watching. I took one last look at the situation trying to take in every detail. The look of pure pleasure on my sisters face almost made me explode in my pants. I slowly backed out of the kitchen and retreated to my bedroom.
I have never thought of my sister sexually before. She is a beautiful girl, standing 5'6 with long blonde hair. After seeing her have sex, it was hard to not think of how sexy she actually is. She grew up in gymnastics and has maintained that figure into her 20's. She has flawless pale skin, and legs that stretch up to the most perfect perky ass. I couldn't get her out of my mind.
I stayed in my bedroom until Alice got home. I wanted to jerk off so bad but I refrained not wanting to sexualize my sister further. Alice walked into the bedroom to find me scrolling through my phone. I sat her down and decided to tell her what I saw. We tell each other everything, and I didn't want to chance this event coming out any other way. Alice was shocked! She kept digging at the details of what I saw, wanting me to describe everything. As I sat there explaining to my wife how I witnessed Tyler thrusting into my sister, I noticed my wife beginning to squirm and bite her lip. She reached over to me and placed her hand on my crotch. I was rock hard. "Oh my god, did this turn you on?" She asked.
I gave her an awkward smile, feeling slightly embarrassed and ashamed for being aroused. "It's ok honey, I understand completely. You are sexually frustrated."
Alice climbed over on top of me and pulled off her top. She often goes braless, complaining that they are uncomfortable and she doesn't really need them. Well she is right. My wife has arguably the most perfect pair of breasts. Her body's proportions are almost unreal with a paper thin waist that rises up to these large perky mounds. She grabbed my head and pressed my face in-between her chest. She began to grind her body into my crotch. I could feel her pussy press up against my cock. The thin fabric of her leggings slid against me. I pulled her over onto the bed grabbing her waistband at the same time. With one motion I pulled her leggings off her body leaving her completely naked. Alice giggled at me and squeezed her legs shut crossing them slightly. She playfully pretended to feel shy that she is so exposed. I watched her struggle to cover up her huge breasts as I undressed completely. I stood over her on the side of the bed slowly stroking my cock. She watched as I squeezed out large drop of precum. I crawled over to Alice and spread my precum across her lips. She gave me the most beautiful big smile of approval. Before she could stick out her tongue, I pressed my lips into hers, and we both mixed our saliva and my precum in a passionate kiss. Alice spread her legs for me and I entered her completely. I lifted my head back and looked my wife in the eyes. She giggled a little and said, I want you to pretend I'm Emily."
