I shouldn't fuck my girlfriend's neighbour

there was a knock at the door

"Are you there is there are you there Andy I was wondering if you had a spare cigarette" It was D, my lover's neighbour

This is happening a more and more frequently. I get it - cigarettes are expensive - but it's hard for me to cover my own needs. D was a character - she rubbed my lover up the wrong way so they didn't hang out much. D was boisterous where my J was quiet. D wore skimpy and see through clothing where J covers up and feels unattractive. The thing is - neither of them meet the narrow beauty standards that dominate our society. But I thought they were both hot as hell. D and J had both put on a lot of weight in the last few years - and that's normal. J retained tiny tots and slender legs whereas D had floppy saggy boobs, a mighty paunch and chunky thighs. I so rated her decision to wear purple string singlets with a thin semi transparent shirt underneath. She is sexy.. and even though I'm poly I didn't think it would be wise to make a move on J's neighbour. But that morning, I couldn't help myself. Yeah I will buy you a whole pack D, but in return can we go to your flat and kiss and cuddle for 10 minutes? Her eyes sparked Oh Andy!! We walked to the shop together and I bought us a deck each. We didn't talk much, just looked at each other and smiled. Back at her flat, she let us in and closed the door. I pulled her against me and kissed her soft lips. Her tongue locked with mine immediately so I molded myself into her, getting harder and not caring if she could feel me poking into her fleshy crotch. She caressed my arse and pulled back from the kiss " Can you please fuck me? I'll buy you 2 packs of cigarettes next week. Oh D yes please!! I pulled off her top and then my own, pressing my slender smooth chest into her wonderful warm soft pendulous breasts. She felt so good skin to skin! I slid her track pants down to her knees and ran my hand gently over her crotch, encased in cheap and skimpy frilly undies. She knelt and pulled down my pants, greedily slurping my stiffening cock into her mouth. I pulled out and said Lie on the floor and get those knickers off. She has barely got her back down before I was between her legs, folding them back over her fabulously enormous tummy and whipping off those panties blocking me from what I knew would be a taste treat. I greedily plunged forward and ran my tongue around her outer labia and teased these lips apart. My cock was like bone and I was drooling with anticipation as I started seriously working my tongue from her hot little cunt to her clit. She was getting really sloppy down there and it wasn't just my drool. D pulled at my hair and whispered urgently Come here and fuck me! She pulled her legs up and out with her hands around her thighs and I knelt before her, sliding my quivering and upward curving cock along her sloppy slit and over her clitoris twice before pushing my cut head into her heat. Oh yes - this is worth the complications. I just can't understand fat shaming - people come in different shapes and sizes, but size is no indication of worth, or even super hot fuck action. I slid my cock slowly and deeply into D as she spread as wide as possible, inviting me all the way into her. This is ecstasy. I slid my knees under her thighs, tilting her pussy up and rolling her butt off the floor slightly, as I leant forward and kissed her chest, her neck, her lips. Her body felt fantastic against mine and I could feel my cock getting even longer and harder and deeper into her stinky fuck hole. Good stink, the stink of fuck. We found our rhythm and she took my throbbing cock again and again and again into her, urging me to fuck her and moaning with pleasure. I was making little soft moans too - this wasn't just a quickie - this was a proper dirty fuck. I wasn't wearing a condom which was naughty - although I've had a vasectomy so at least there'll be no babies. And at this point I wanted to fill her incredible pussy with my come. Can I come in you, I asked? Not yet, not yet! We kept sliding in and out, her pelvic motion synchronised with mine so our fucking was like the ocean - mighty and unstoppable. At some point D squeaked I'm coming, come with me and I relaxed my clenching, thrusting against her warm soft voluptuousness and heading towards the cliff of orgasm. There was a flood of hot wetness where we joined and D nodded, wide eyed. Fill me up do it now!! I became delirious and ecstatic as her throbbing and quivering pussy drew a mighty squirt of semen and another and another, jetting deep into the ends of her heavenly fuck hole. We were both sweating and shaking - I lay on her and held her tight, kissing her and slowly withdrawing from her. We cuddled on the carpet and our juices seeped from us across our skin. This will take some explaining, but I think it's going to happen again.
