Part one was the first time I've shared any of my naughty secrets online and I enjoyed it - I think Karl enjoyed it too when he got home and caught me on here! ;-) Anyway; so I'd had a shower and brought myself off as I was so turned on by seeing Mel and Niall fucking with their bedroom door open. I couldn't get the image out of my head of her tanned, toned little bum sliding up and down on Niall's seemingly giant cock. I'd thrown a towel round myself and wandered back down to the kitchen to get a cold drink and have another peek... At first i thought it was quiet in their room, but as I peered round the door I heard wet slurping noises and then saw mel on top of Niall locked in a passionate 69. Her little arse was squirming as she ground herself onto his face, but again it was his cock that got me; mel was facing me but had her eyes closed, moaning as she suckled the big head of his penis and wanked him slowly with her little tanned hands. What turned me on most was that his cock was hard as steel and was so messy, covered in cum and I loved the thought that only a while ago I'd seen him pistoning in and out of mel and now she was licking it all up. My hands wandered under the towel to my breasts and I pinched my nips slowly as I watched them both with their faces buried in their most intimate parts. Suddenly, Mel choked on Niall's cock and looked up and I jumped. Smiling, she said "Shell, I can see you - we wondered when you'd be back". Even though Mel and me had dabbled in a little naughty fun before, I was still embarassed to get caught out watching my mate 69 her fit new boyfriend. I sheepishly entered the room and stood by the bed. Niall shifted under Mel and she ground her hips down further saying, "Don't stop on my clit, baby, don't stop". Smiling up at me, gripping his cock at the base and pointing it forwards Mel asked "want some?". Well, I didn't need asking twice and dropped to my knees on the floor, leaning forwards over their bed and immediately engulfed Niall's hard tool inside my willing mouth. Niall moaned and Mel giggled, she stroked my hair as I swirled my toungue round his big purple head, tasting the most beautiful mix of his cum and her juices. I let his cock drop out of my mouth and moved down to his balls, sucking each one in turn as Mel pulled his legs further apart and exposed his tight asshole, which I licked as I continued to pull him off in my hands. "I want to see you fuck him" said Mel, still sat astride Niall's face as he licked her out. I stood up and let the towel fall off, or what was left of it anyway! Mel sat upright on Niall's face and cupped her own pert little tits as she gazed at my body, taking in my full round breasts and then looking down to my moist shaven pussy. As I straddled Niall's hips and lowered myself down his long shaft, mel's hands were all over me, groping my tits then playfully smacking my arse. Niall's cock slid all the way up me and felt sublime! He was thick as well as long and I could feel my pussy stretching to fit him in. I must have closed my eyes briefly because I hadn't realised that Mel had leaned forward and was now sucking my nips. We'd done this before, but her mouth was so wet and warm, soft - not like a man's rough play. I bucked harder on Niall's cock as she moved up my body and kissed me full on the mouth. I held the back of her head to pull he closer and ground my aching pussy down to Niall's balls; feeling like his tip was poking into my womb! My hands wandered over Mel's tight little body and I cupped her pert little tits, squeezing them together and flicking her nips with my fingers. All of a sudden she cried out, then bucked and flew her arms about as Niall must have finished her off with his tongue inside her. Becoming too sensitive to sit on his face any more, she got off and went to the arm chair, leaving his face wet and red. Staying astride his thick cock, I looked Niall in the eye and ran my hands over his muscular chest before gripping his shoulders tightly. Niall hardly moved as I bounced up and down on his hard shaft, with Mel shouting filth from the armchair as she encouraged me to "fuck him harder" and "fill her cunt, you bastard". Niall was clearly getting closer and the slurping slapping noises of our genitals banging together were more intense. He suddenly broke free of my grip and spun me over, with him now on top. Gripping my ankles and pulling my legs wide apart he plunged his thick cock back into my soaking pussy and fired it in and out of me like a jackhammer, grunting and groaning as he got me to the brink of orgasm. I looked across at Mel, who by now had her own legs wide apart draped over the arms of the chair and was frantically rubbing her clit with one had and pulling her nips with the other. I couldn't moved, I could only lie and get fucked by this madman and his monster cock. Locking my legs behind his shoulders, Niall freed up his hands and used them to grip my big tits so hard they hurt, but I loved the intensity. I think I'd cum a couple of times myself by then and I'm sure I'd heard Mel cum too already on her own! With an almighty grunt, Niall sunk his cock into my wet cunt so deep that I could feel the base of his cock grind against my bare pussy. In a few big thrusts, he had pumped me full of cum, slipping out halfway through cumming he'd even fired a load over my tummy. As Niall laid next me to me in a sweaty heap of muscle, I realised I was still panting hard as I ran my fingers over my tummy to smear his hot cum all over myself, bringing my hand back to my mouth to taste a little of his love juice...
