It was a warm sunny day and I was heading to the garage to get the car checked out. I’d not long been driving before I spotted a familiar figure walking along on the pavement. I checked my mirror before slowing to check them out, yes it was Catherine, she was carrying a couple of bags, so I pulled over. I pressed the button to open the passenger window and called over to her. She had headphones in so it took a couple of calls and a honk on the horn but eventually she stopped and walked over to the car. I wasn’t in a rush to get to the garage as I’d planned a drive first to let the car run so I offered her a lift. It was the gentlemanly thing to do considering she had her hands full. She was reluctant at first, afraid to be seen with me, but the heavy bags and potentially long walk meant she gave in. Opening the back door she put her bags in, pushed them over to behind me and hopped in the back. I think she felt this was more discreet, like being in a taxi. I asked her where she was off to and she responded with an address a bit further out of town. It was only a few minutes in the car but a lot longer by foot. I took it upon myself to take the scenic route just to keep her in the car a little longer, she either didn’t notice or mind. We made small talk and I asked her what was in the bags. She explained she was taking clothes to a friend’s house because her kids had outgrown them. Unfortunately, despite the detour, the journey was over far too quick. We stopped in the road, Catherine grabbed her bags, opened the door and we said our goodbyes.
It was a cul-de-sac so I drove to the end of the road to turn around. I watched Catherine in the rear view mirror as she walked up to house near where I had dropped her. I was surprised to see a guy answer the door but just assumed it was probably the boyfriend or husband. I was still running early so I pulled up and parked and took the opportunity to check my phone. With a clear line of sight to the house I soon noticed movement upstairs and the curtains closed. Weird I thought, had I seen Catherine up there with the guy. It was then that I noticed a smaller bag left on the back seat. It must have fallen out of one of the bigger bags and she hadn’t noticed. I suppose I better drop it in before I leave. I grabbed the bag from the back and got out the car and started to approach the house. I couldn’t see anyone downstairs but that didn’t mean they weren’t out in the kitchen or something. Getting to the door I noticed no bell so gave a knock and waited, nobody came, I knocked a bit harder which gave me to realise that the door wasn’t locked. Being a postman and having knocked on many doors it’s a skill useful for determining if someone is actually going to be in. Still no answer. I thought about giving up but decided to send a message, a couple of minutes passed with no response. Looking over the back gate I was able to see that there was no one in the kitchen and that’s when curiosity got the better of me. I glanced around before trying the front door, it opened, heart beating heavily I leaned in and listened. There were recognisable noises from upstairs and I thought she can’t be. Before I knew it I was creeping up the stairs and before I knew it I was at the bedroom door. It wasn’t shut and looking through the gap I could see Catherine naked on all fours on the bed, luckily she was facing away from the door otherwise she would have seen me. I could now hear the sounds of skin smacking against skin and the moans of pleasure as the engaged in rough sex.
I kept watching enjoying the view but secretly wishing it was me positioned behind that beautiful ass. I slowly pulled my phone from my pocket and activated the camera. I took a few shots and then activated the video trying my best to hold it still in my shaking hand. My other hand was subconsciously rubbing my hard cock through my jeans. As the adrenaline started to subside I began to realise there was a chance to leave or walk into the room and take my chance. It was in this moment that the two switched positions on the bed. She turned towards the guy that had been ploughing her wet pussy and took his dripping cock in her mouth and started giving him a blow job. I wasn’t sure if she had seen me or not as she turned, she wasn’t wearing her glasses. I decided to position myself so only she could, remembering how she’d mentioned that she’d like to be caught and watched. It seemed to take forever before eye contact was made, there was a moment of recognition and she just carried on. I wasn’t sure what to do next. Common sense said to just leave but I’d come this far and this may be my only chance to get what I’d so desired. I slowly backed down the stairs then announced my entrance, apologising for the intrusion and started up the stairs again. There was no movement from the bedroom so I just tried to casually walk in with the bag held forth hoping it was enough to explain my intrusion. They both just looked at me, maybe expecting me to leave or at least say something but I think at least Catherine knew what was to happen. She was already back to getting her pussy pummelled, I can see why she chose this guy, his stamina was good.
I moved into the room to a chair at the top of bed where Catherine could see me. I watched her face as she faced forward, her eyes were closed and mouth slightly open from which the occasional ‘oh fuck’ and ‘yes’ moaned from. I slowly undid my jeans so I could free my bulging cock, I stroked it as I enjoyed the show. I took off my shoes and stepped out of my jeans so I could approach the bed. I reached out and put my hand under Catherine’s chin and directed her to my waiting cock, she was a little surprised by my new position but caught up in the moment began sucking away. It wasn’t long into the blow job/face fucking that the guys stamina finally waned and he moved to sit on the other side of the bed. I saw this as my chance to assume his position and withdrawing my cock from Catherine’s mouth I approached the end of the bed. I admired the ass before me and ran my hands over it and found the wet pussy between. I gently fingered it, gauging its size and position before I would line my cock up with it and plunge it deep inside. I just slid straight in but it hadn’t been stretched too much that I couldn’t feel it around my cock, it felt amazing and I held it there for as long as I could before I gave into the need to fuck her. I started thrusting in and out, pacing myself, not wanting to cum too soon. She shifted herself to take the guys cock in her mouth and I did my best to keep myself inside her. I began to pick up pace, I wanted to make her orgasm and cum inside her. Neither of these things I was certain should or would happen but I kept going. It was then that I glanced down at the bag on the floor and noticed that it was actually partly filled with sex toys rather than clothes. I reached down and took a small vibrator from the bag then turned it on and placed it against her clit. It was awkward but I managed to keep it in place while I resumed fucking. It didn’t take long before I could feel Catherine’s body reacting to all the stimulation. I alternated between fucking her harder and placing the vibrator on her clit till I was certain we both would cum. Her moaning had got louder as she no longer had the guys dick in her mouth and then I felt her pussy start to tighten around my cock, this then set me off and I fucked her hard and deep as I could. This put me in a position where I was now bent over her, one hand on the bed keeping me up and I’d managed to find a breast to squeeze with the other. I too then began to orgasm and unleash a large load of cum inside her. She collapsed underneath me and I withdrew from my position. Before too much clarity could kick in I decided it was best to leave, the other guy would keep her occupied now. I picked up my phone, stopped the recording and took one last pic before grabbing the rest of my stuff and finding the bathroom. By the time I’d cleaned up and dressed they were back at it. I headed downstairs and back to the car.
