I play amateur rugby for a club in the North West of England. It helps keeps you fit and makes you friends and of course all the girls seem to like a rugby player. My best mate on the team is a young South African guy, who lives over here called Gareth. His girlfriend of the last couple of years is Dianne. She is quite a bit older than him and to be honest I’ve always wondered what he saw in her. She’s 40, a brunette, about 5’3, Nice tits, with a biggish arse. Cute without being gorgeous or anything. I’d never thought about fucking her. After all she’s a mates girl, until that is a couple of weeks ago. I’d been to their house on a number of occasions and Dianne had always been pleasant. This night I called round on a Friday to see if Gareth fancied a pint. Dianne answered the door and invited me in. I explained what I was there for and She told be that Gareth was away with work till Tuesday. But she also said that she’d just opened a bottle of wine and asked if I wanted to share it and keep her company. “Why not” I thought. We drank and made small talk (mainly about Gareth), then Dianne opened another bottle of wine and I started to notice that her top was open lower than it had been and that a lot of her breasts were on show. After a few minutes Dianne caught me looking at her tits. But she was far from angry. She just teased me that I was a naughty boy and followed that by very suggestively saying, “Don’t worry I won’t tell Gareth, whatever you get up to”. I Looked her up and down. Her breasts looked very inviting and her skirt had ridden up so that she was showing a lot of leg as she half sat, half lay on the sofa. I though well if my mate won’t know why not! I moved over to her and placing a hand on her thigh and kissed her. She responded kissing me back hard and I allowed my hand to slide up her leg and started to rub her fanny though her panties. She gasped then carried on kissing me but her hands were undoing my shirt buttons and then she stroked my chest. After a little more of this “heavy petting” she slid apart from me, stood up and as I sat there watching she stripped her clothes off. She slowly unbuttoned her blouse. Then unzipped her skirt and slid it off. “Fuck me” I thought, this is my best mates girl! Then her bra came off and her tits were on show and all thoughts of my mate went out of the window, as I knew I had to fuck her. She knelt in front of me, undid my jeans and took out my very stiff cock. As she held it she ran her tongue slowly from my balls to the tip of my cock. She then sucked my shaft for a few moments, before licking my length again and again. I was in heaven as she concentrated on licking and sucking my balls before sucking my stiff length again. She was amazing, each time I felt I was about to explode she would back off and let me calm down a little. Until after ages she decided to finish me off. She took my cock into her mouth and her bobbing head picked up speed. I warned her I was about to cum and she just carried on sucking. It felt like my cock exploded my sperm into her mouth. I was bucking on the sofa as she swallowed and sucked. Just a little of my spunk escaped her mouth and dribbled down her chin. But when she let my cock drop from her mouth she ran her finger up her chin, catching every sperm and then licking them from her finger. She just said “your turn “ and then took my hand and led me to the bedroom. I tore off my clothes as Dianne stepped out of her panties. I looked at her neat fanny. It looked recently shaved and a thick strip had been left. She lay on the bed, spread her legs and then ordered me to lick her out. I took my time at first but was told to lick harder and so I licked her clit as hard and fast as I could and fingered her hard as I licked. My wrist, jaw and tongue ached like hell but I was determined to make her cum. After and age she gripping my head, forcing me into her cunt and screamed that she was cumming. She bucked and groaned and I tasted the warm juices filling her slit. We lay stroking each other, recovering and looking at each other’s naked bodies. Dianne had barely said a word to me and yet she’d swallowed my spunk and let me lick her to a shattering orgasm. Now she was slowly wanked me back to hardness as she told me what a great looking cock I had and how she wanted it in her fucking her hard soon. She got it! Soon enough she had me good and hard. From her wanking, sucking and very dirty talk. Within seconds of getting hard I was banging her hard from behind. Slapping her big arse as I rammed my meat into her. The rougher I fucked her the more she loved it as she screamed to be fucked harder. I was soon filling her hot cunt with my seed and as she ground herself into me and my cock pumped sperm into her I couldn’t help wondering what my mate would say if he knew. I fucked Dianne for the rest of the weekend and she delighted in telling me how well I shagged her and how Gareth would have a lot to live up to on his return. “Don’t worry I won’t tell” she reassured me before swallowing another load of my spunk. As I left on Sunday evening I swear I could barely walk. I had given her my number and as she said “Gareths away a lot and I do like you keeping me company”
