I was stood at Donna's front door, ringing the bell. Peter answered the door, I took a pair of red panties from my pocket. "Donna in?" I asked pushing past him, "She left these in my car last night," I informed him. He looked confused at me. "Yes your wife Donna, you know the one, she left these in my car last night in the carpark behind Woolworths. There she was stretched out on the sofa. She looked up to see me twirling her panties around my finger. Peter knew I was fucking Donna and I knew, he knew, I was fucking Donna. I was sick of the pretense and had decided to put things on a whole new footing. "Hi Donna, thought I'd return these," I told her flicking them by their elastic at her. "Thought you'd get cold without any panties on," as I flicked her skirt up showing she was wearing some Blue ones today. "Huh, blue ones, weren't they the ones you left in my car last week?" I quizzed. Peter finally found his voice," You didn't leave them in his car did you dear?" he asked Donna. I butted in before Donna could answer. "You remember you left them last week when I fucked you in the back seat of the car. Oh he means the red ones, that was when I gave you the blue ones back and fucked you over the bonnet of my car last night. That shut Peter up, he was lost for words still taking in that I had admitted to fucking his wife on several occasions. Donna had gone quite red with embarrassment, know everyone in this triangle knew who was fucking whom. "Your nearly as red as your panties," I told Donna. " Nearly as red as your pussy was when we finished last night. Are you still red I asked reaching for her panties." She moved to prevent me from grabbing them. "Don't be shy now," I told her, "we've both seen it many times before." Peter had slumped into an armchair and sat there with his mouth open. "You don't mind if I have a look do you Peter?" I asked him not caring what the answer would be or if there was an answer. This time when I grabbed, I caught hold of Donna. She struggled to get away. " You didn't struggle like that last night or any of the other nights when we fucked," I told her. I pulled her over my knees as I sat down beside her. Her panties were on full show. I stroked her arse a little and she moaned. "Look Peter, she likes her arse stroked," I told him, just before I pulled her panties down, "no its not red tonight is it Peter." His eyes were on stalks looking at me showing him his wife's fanny. "Perhaps it only goes red when I fuck it," I mused, as I inserted one then two fingers. Donna was wriggling trying to get away, but as soon as the two fingers were inside her she just lay there groaning. "Not gone red yet Peter," I informed him, although he could see for himself. Donna was now pushing back on my fingers trying to get them deeper. "Look Peter she likes this, see how she moves to get more fingers. Still not red though. Perhaps I have to fuck her?" I could see that Peter was now sporting a hard on. "Do you want me to fuck you Donna?" I asked her. Donna just groaned. "I take that as a yes shall I?" I asked her. Not waiting for a reply I removed her panties completely along with her slippers. I lay her on her back on the sofa and stood unbuckling my trousers and letting them drop to the floor. "Oh how rude of me, You don't mind me fucking Donna do you Peter," I asked. not waiting for a reply, "Thanks Peter I knew you wouldn't mind." Then I had my shoes ,socks, trousers and boxers off. "Think I'll fuck you Doggy style," I told Donna, maneuvering her into the best position for Peter to see his wife being fucked. Then I was behind her with my cock just touching her pussy lips. "Do you find her tight," I asked looking at Peter. Then I eased the head of my cock into her pussy. "Look Peter, it's in her." Then with a few strokes I was balls deep. "Look how deep it goes," I told peter. He already knew as he was leaning forward from his chair, watching my cock plowing in and out of his wife's pussy. Donna was moaning loudly as I pounded her pussy. "She's a good fuck isn't she?" I asked Peter. Donna was thrusting back on my cock. "Does she do it for you like this?" Peter shook his head. "You mean she doesn't fuck you like this?" I already knew that he only ever fucked her in bed with the lights of in the missionary position. Here I was fucking his wife in daylight on all fours on his sofa. "Perhaps if your lucky she'll let you have a go like this," I taunted Peter. Then Donna came and writhed and thrashed about just before she went stiff with her arse pushed back hard on my cock. She was groaning very loudly. I shot my load in her pussy. Then we were both slumped on the sofa bathing in the after glow. Then Peter finally got out of his chair and fell at Donna's feet and licked my come and her pussy juice from her fanny. "I didn't think you had it in you Peter. Donna says that you never go down on her and here you are licking her out." I told Peter. "Tell you what Peter, instead of me taking Donna out tomorrow night and fucking her in the car, I'll just come here and fuck her in your bed. That ok with you?" again not waiting for Peter to reply, "Thanks Peter I knew you wouldn't mind. Saves Donna from getting her pretty little arse cold." Peter had finished licking Donna out and had started to put Donna's panties back on her. "Don't bother with that Peter, I might just fuck her again. Don't mind do you." Peter just had a silly sort of a grin on his face. I pulled Donna up and dragged her upstairs and into their bedroom and lay her on her back on the bed. I was getting hard again as I fingered her pussy and bared her tits. Peter had followed us, just in time as I raised her legs up and pushed my now hard cock back into her pussy. "This is a good position Peter. It goes in deep like this," I informed him. Then I was slamming Donna's pussy real hard. The slapping noises of our bodies meeting almost drowned out Donna's moans. "She likes it like this Peter, She likes it nice and deep." Just then Donna came shaking her head from side to side. "Think she liked that Peter," I teased. Then I moaned as I pumped my second load into his wife's pussy. I rolled on the bed to recuperate from my efforts. Peter was back between Donna's legs licking her fanny clean. "It's all red now isn't it Peter," I teased. Then when Donna had recovered we lay kissing whilst Peter kept on licking and sucking Donna's pussy. It was getting late in the afternoon and there was things I had to do. "Sorry to have to leave you Peter. It's been a lovely afternoon, but I have things to attend to. Never mind Peter I will be back tomorrow night. That'll be good wont it?" again I didn't wait for Peter to answer. "See you tomorrow," I told him as I kissed Donna goodbye and went down stairs, dressed and left.
