Right from when we 1st met, my wife Sammy made it clear that she craved fresh cock from time to time so I decided I could live with the situation and have done reasonably happily for years. Thinking of it tortured and excited me and I sort of wanted to watch but was never invited and hadn't the courage to ask. And then she met Scott who seemed to have a bit of control over my usually domineering woman. She'd get out of bed in the early hours to attend to his needs. And one night he fucked her in our hallway after he'd been on a night out while I lay in our bed. She'd enjoyed that fuck by the sound of her squeals. Anyway, he wanted to fuck her in our marital bed which was hitherto forbidden. And he wanted me to watch. Any other lover she'd have told no but with Scott she put it to me. My hesitant yes earned me a cum in mouth blow job, a rarity. On the day I went to work sick with nerves and with a boner that wouldn't subside. Arriving home I saw Scott's BMW already parked on the drive. I threw my bus pass on the table and heard giggling from upstairs. Shaking with nerves and excitement I climbed the stairs and pushed open my bedroom door. I saw Scott in my bed. "Hey Paul!" He grinned widely tipping his can of lager toward me"how you doing?" It was then I noticed Sammy's feet sticking out of the quilt, her head would have been around his crotch region so I guessed he was being pleasured. He lifted the quilt "hubby's home babe," he said. I heard a muffled grunt. "She's got her mouth full mate" he put the can down and settled his head on the pillow moaning contentedly. "She's good ain't she Paul? Oh you don't get it much these days do ya?" Defencively I told him about my recent gobble. He pretended to be impressed. "But you didn't do this tho did ya ?" His hands disappeared inside the quilt and he began violently thrusting his hips to which Sammy squealed and spluttered. "She likes her face fucked Paul," he said thru gritted teeth "you need to fuck your woman. Fetch me another beer mate" arrogant bastard but my cock was rigid as I went to fetch his beer. As I went back up the stairs I could hear him moaning "ah yeah baby that's good, keep doing that " Walking in the quilt was gone, Scott was on his front while Sammy licked his hairy arse. She waved at me quite sweetly. After a while Scott turned over. "I need pussy babe" he said. Christ his cock was huge. He beckoned and she complied. He rubbed his cock against her wet snatch and then applying firm pressure on the small of her back he disappeared inside her. "Fuck me good baby" he said holding onto her ample swinging tits and as she began to move he motioned at me to hold his beer to his lips saying "got my hands full" in between sips he talked " I like her titties. Going south a bit but a nice size. Mmm that's it baby. She's got a nice tight cunt Paul, you ain't too big are you? She likes mine don't you babe. Oh here she goes, that's it baby, that's the way, faster. Here she goes Paul. Cum sugar cum. Yeah that's a big one. Nice. You've never seen her cum like that have you Paul ?" She slumped onto his chest and I even brushed her hair aside to give Scott more beer. He lifted her off him and lay her on the bed. "You wonna fuck her Paul?" I tore my clothes off and he moved aside to let me in. She opened her legs obediently and I slipped in fucking fast although Sammy couldn't really feel me. However the excitement of the situation soon had me spunking. Scott pulled me off and put Sammy on her tummy llubing his cock. I'd never been in Sammy's arse but he was going to do her there. "No" I protested. "Shut the fuck up " he shouted as he thrust up her taboo hole. She looked in pain but said to me "it's ok, it's the only place he can cum" I held her hand as he fucked harder pulling her hair back. I couldn't tell if her face was contorted in pleasure or pain but I guess it was pleasure as they came simultaneously and then lay in a sweaty mess. Scott slopped out of her and announced he was going for a shower. A spent Sammy lay motionless but I got hard again. I got on her and entered where Scott had just withdrawn. Again Sammy lay motionless while I fucked in excitement again spunking very quickly. A freshly showered Scott stood in the doorway and clapped before dressing. He kissed the well fucked Sammy passionately on the lips saying he would see her in the morning. She smiled back thru hazy satisfied eyes. I can't help thinking that this time I may lose her
