I dropped round my mate Sam's house as he said I could borrow a couple of tools to fix my car. I knew he was at work and said they were just inside the garage door. I tried the door. He had forgotten to leave the door open. I let myself into the kitchen which was unlocked. I was expecting to see Becca but there was no sign of her. Then I heard a noise from upstairs and went to look for her. She was there alright, but she was in just a flimsy bra and panties, and tied to the beds headboard by her wrists. To top that she had a blindfold on and had no idea that I was there. I stood there looking at her. I had often fancied Becca. It was hard not to as she is a tall long legged blond with large tits and very friendly. Talking of hard, my cock was like and iron rod and it almost hurt. I moved a step forward and looked between her legs at the few pubic hairs that had escaped the panties. She was definitely a true blond. The collars and cuffs all matched. I took another step forward. Suddenly she knew someone was there. I wasn't sure if she heard me move or if it was my aftershave. "That's enough now Sam. Untie me and take this blindfold off," Becca ordered. I stood frozen for a few minutes. I wasn't sure what to do. If I untied her she would know it's me and not Sam. I was about to move into flight mode when Becca added, "Well for gods sake do something to me." Excitement now won over fear and I took another step and put a hand on her tits. Becca groaned and thrust her breasts at my hand. I slipped my hand between the bra and her tits feeling the soft pliable flesh and the heat in them. They were gorgeous. Becca groaned and said, "Yes, play with those titties. I was in luck the bra had a front fastener and was easy to flick open. Her titties spilled out. I had seen them in a bikini before but never swinging free like this. I bent forward and took a nipple into my mouth. There was a gurgling noise come from Becca's throat. I was now swapping sucking first one nipple and then the other, whichever one wasn't being sucked was being mauled by my hands. "Finger my pussy Sam, do it. Please do it. You bastard you can't leave me like this, " Becca pleaded when I hadn't moved. I could now see a damp patch on her panties. I leaned over and gave it a light rub. "Ooooh, Ahhh," escaped Becca lips. "Yes please do me," she asked. I slipped a hand inside the panties and stroked the damp pussy. More moans and groans escaped. I let go of her tits and with my other hand moved her panties to one side. She had a nice blond bush just above her crack that was already gaping open exposing her clitoris. How many times had I dreamed of getting into Becca's panties and now I was and she was groaning encouragement even if she did think it was Sam. I moved to be completely between her legs and dipped my head down towards her pussy. I only intended to sniff it, but passion overcome me and my tongue snaked out and licked her exposed clitoris. Becca let out a long deep groan. "Yes Yes Yes," was all she said as my tongue played with her clitty. I continued licking for quite a long time. "Fuck me now, Please fuck me," she asked. I wasn't sure which of us needed to fuck the most, Becca because I had worked her up or me as my cock had been aching for some while. I stepped away and dropped my trousers and boxers and then pulled Becca's panties down and off. As I climbed back between her legs I raised them and put them over my shoulders. Then I lined my cock up and slowly drove it into Becca's pussy. It slid in fairly easily. Then I started to slowly plunge in and out of Becca's pussy to loud moans and groans. Becca was thrusting her arse off the bed to accept and take as much cock as I could give her. She moaned and groaned as I quickened my pace and played with her tits. Becca was straining for me to kiss her as I pounded away at her pussy. I bent further forward and engaged in a kiss. Silly me, I have a tash and Sam is clean shaven. Becca stopped for a brief moment when she felt my tash, then she was thrusting again with a renewed vigor. I could tell that Becca was on her way to her orgasm and I wasn't far behind. Becca was aware of this and said, "Come in me. Yes Argh," as she came and I was just seconds behind pumping my cum into her pussy. After we had recovered a little I replaced her panties and quietly left Becca still tied to the bed. Later that evening I returned and Sam welcomed me at the door. He apologized at forgetting to leave the door open for me. I told him that other things came up and I didn't have the chance to get around to the repair so it didn't matter if he forgot to open the door. Well some of it was true, something had come up and I had been too busy to start the repair. Sam went to get the tools and as he did Becca said, "You had better come around again tomorrow and see what I had got. She winked at me just before Sam returned and although Sam offered me a beer, I declined saying I had things to do. I lay awake half the night wondering what Becca had that she would wink at me about. My wife asked if I was alright as I was so restless and eventually I went to the spare room so she could sleep. Next morning at ten I returned to Sam's house. Becca was waiting for me. "Come in lover," she said. I was told to sit on the sofa and look at the TV. Becca set the player going and right away I could see that she had recorded our session from the previous day. She told me that when Sam decides to play one of his games with her he rigs the video camera up to record them in action, only this time he caught me fucking his wife. After Sam had returned home he fucked Becca and before he had a chance to review the tape Becca swapped it with a blank tape and hiding the evidence of our encounter. As I sat watching the tape I found my cock straining to escape again. I was lost for words and just sat glued to the screen. Becca had spotted the bulge in pants and after a while took my hand and led me back to her bedroom. The sex session that followed was intense and insane to say the least, and I fucked Becca both on her back and also on her front. As we lay on the warm down from our efforts I asked about Sam. Becca told me that she would tell him sometime, but for now it was just our secret. I was alarmed that she would tell Sam and that could wreck my marriage. Becca told me not to worry as her and Sam had an open relationship and she had her men and he had some women he saw. Occasionally they would swap with another couple or attend a party, but for now she wanted me all to herself. Becca suddenly grabbed me by my ears and pulled me towards her pussy, "Lick it again like you did yesterday," Becca asked. I was quickly back licking her pussy. After an appreciated period I moved Becca to standing on the floor and bending over the bed. I pounded her long and hard from behind. Before I left Becca gave me the tape and told me that I should keep it well away from my wife as she wouldn't appreciate it. Far from it, it would have resulted in a divorce. When I managed to watch it, it had not only caught me, but also Sam as he pounded Becca for some sloppy seconds. Not that he knew at that time. I was now fucking Becca on a fairly frequent basis. Then one evening, about ten months later, I was in the pub with Sam and as we sat drinking our beers he calmly said, "So you've been fucking Becca." I almost choked on my beer. "Good for you," he added, "I gather you caught us in the middle of one of our games and took advantage of it." Man was I glad he laughed. "Shame your missus wouldn't join in." I asked him to not go there as the inevitable outcome would be a divorce. He said he knew and wouldn't spoil things. Later after a second beer he told me that he had something for me at home. Later back at his house I found Becca again tied up with her blindfold on. Sam made sure his camera was rolling as her pushed me to start with Becca. I went straight for her pussy licking and fingering it. Becca knew there was both of us when Sam pushed his cock into her mouth. It wasn't something I had tried with her but decided that it was a must for another time. I fucked Becca first and then Sam took his turn, telling me that Becca was happy to suck my limp cock. I hadn't had to wait long to have my cock in Becca's mouth. I wished my wife sucked cock that good. I fucked once more before going home to my wife. That was eleven years of fucking Becca before the Corona Virus issues. Sadly since the first lockdown I have only had my wife to keep me happy. In the year that we have been pretty isolated, I have got my wife wearing blindfolds and tied to the bed. She wasn't happy with me using our camera to start with but since it led to several great sex sessions when I played it back, she has got used to it. If only I could get Sam to fuck her when she's blindfolded like I did to Becca.
