Taken by Two (part 2)

As I said at the end of part 1 I felt like the favour needing repaying. He had never mentioned it being a fantasy but heck all guys have thought about being with two girls right?. The thought went out of my head completely for a while, that was until an opportunity presented itself. I won't go into too much detail but unfortunately when I was 18 me and my sister had a huge fall out and we barely spoke. For a while we had been having arguing with our mum and when I got together with Matty I spent a lot of time at his house to get away from it. As time passed I started to sleep at his house more and more and eventually moved in with him. This caused friction with both my mum and my sister. My mum just didn't like the fact I was moving out and my sister felt like I was abandoning her and leaving her on her own at home. I told her it wasn't like that but after many arguments we hardly spoke. We would speak whenever I went home but when we did talk it usually ended up in an argument.    

                                                                                                              A year or so later she turned up at our house in floods of tears saying she had had a huge argument with our mum and apologised for us falling out. Matty offered her refuge and she moved in with us. We soon patched things up and she became a happy part of our household. She soon find out we were all very open after seeing Matty walking around half naked after a shower. Having a naughty side like me she soon accepted it and joined in. One evening she came into our room in just her underwear to ask me something and when she went Matty laughed and said by heck, i've got two of you now, its a good job I can tell you apart. I laughed and then my mind had an idea. He did have two of us and now it was time to repay him. A few days later she made a passing comment about his mate and I told her what had happened. She was jealous having still not had any sexual contact with a man. I asked if she wanted to change that. She asked me what I meant, quite excitedly,  so I told her my plan and she readily agreed. The following night he was working and myself and Casey were at home chilling out. He text me and said he was on his way home and asked if I needed anything. I told him no and then me and Casey stripped down so we were both just in our knickers and got into bed. He got home and came upstairs and found us laid in bed watching TV which was common practice for us.   As he stood there talking to us I felt myself getting excited knowing what we were going to do. He started to take his work clothes off to get changed and go shower. He got down to his boxers and we both said his name. He looked round and we flipped the duvet off revealing ourselves. His jaw almost hit the floor and he went to speak but he could only mumble nonsense as he tried to come to terms with the sight in front of him. I walked over to him and put my finger on his lips and told him to shush. I led him over to the bed and pushed him down next to Casey. She took his left hand and cuffed it to the headboard and I did the same to his right. He went to speak again and I told him not to talk, just watch. He looked at me puzzled until we both knelt across him and started kissing  . Our tongues slowly ran over each others and our hands ran up and down each others bodies. I heard a gasp and looked round to find him staring at us slack jawed. We both giggled and continued our kiss. I brought my hands up to her boobs and softly massaged them and pinched her nipples. She moaned into my mouth which made my pussy moisten. I stopped kissing her and moved my head down to lick her nipples. Her head threw back as she moaned. I kissed and sucked her nipples for a while before kissing down her tummy. I reached my hand down and pulled down her knickers. I flung them at him and ran my hands down to her sexy bum and slowly squeezed it as her tongue found my nipples. I looked over at Matty who was frozen staring at the scene unfolding in front of him. My eyes travelled down and landed on the bulge growing in his boxers. Her hands ran down my body and slowly pulled off my knickers which she flung on top of mine on his chest and her fingers slid between my legs and stroked up my clit. I shuddered and did the same to her. Before long we were leaned over him kissing and rubbing each others clits. We were both moaning as our bodies filled with pleasure. I felt her bringing me towards orgasm and I know her well enough to know she was too. I broke the kiss and whispered to her to wink at me when she was going to cum. We continued rubbing for a few minutes and she moaned out and winked at me. I let go of the orgasm I was holding back and we both started moaning and trembling as we both came. Once the feeling had died down we both looked at Matty who just nodded and said Wow! We giggled and Casey said you know what Gem, I think he should get some fun now what do you say. I nodded in agreement and we laid down next to him on either side and we slowly ran our hands over his chest and stomach. He groaned out and I moved my hand a little lower and brushed over his bulge. The jump his body gave as I did was good, it meant his cock was getting really horny. We took it in turns to gently brush over it until he was groaning in pleasure. I reached down and pulled it out and started stroking it. He moaned as I rubbed up and down his shaft. The previous day when we had discussed this Casey has asked how far she wanted me to go and I said she could go as far as she wanted. She asked if she could touch and suck his cock and I said I would love to see that and I would to have him eat her out. She got excited at this idea having never had it done by a guy. He loves it when I get dominant with him so I gripped his cock in my hand and said you are going to make her cum and until you do you don't get to, understand?. He nodded and he reached out towards her. I shook my head and said no fingers. Casey stood up and moved across to him and knelt down resting her pussy on his face. He started lapping at her pussy and it looked so fucking sexy. I resumed the rubbing of his cock and leaned down and sucked on the head. He groaned out and I looked up and watched him licking and sucking on my sisters pussy. I was getting so turned on and could feel my pussy dripping with excitement. I could feel his cock tightening in my hand and I slowed down and told him he had to wait till she came. I stroked it and licked achingly slow making him moan. By now she was moaning like crazy, her hips bucked back and forth as she rode his tongue. Her moans got louder and louder and she said she was close. Suddenly she screamed out and began to shake. As she did I sucked his cock deep into my mouth all the way to his balls. As I did this I felt it tighten and he groaned out as his cum shot out and all over my tongue. Casey stood up and sat on the bed next to him whilst I sucked every last drop off his cock.   I told him it was my turn and stood up and sat on his face. His tongue lapped up my pussy and I moved forward so he could lick my clit and tongue my pussy.   I looked down and found Casey stroking his cock with both hands. It looked so nice and made me so horny. When she took his cock in her mouth I almost came instantly.   She looked so god damn hot. I held back enjoying the pleasure until I couldn't take it any more. My pussy burst in pleasure and sprayed cum all over his face. I leaned forward on to his chest for support as pleasure filled my body. I heard a scream and I looked down to find his cock spurting cum all over her tongue and her boobs. I giggled and flopped down happy.  I was in the perfect position to suck his cock again. I licked up one side of his shaft whilst Casey took the hint and licked up the other side. He moaned and shook as both our tongues ran up and down his cock and licked over the head. It didn't take too long before he was spurting more cum out of his cock as he went stiff and moaned out. He asked if he could have the cuffs undone as he wanted to do something. I unlocked the cuffs and he grabbed me and threw me down on the bed. He turned round and grabbed Casey and threw her down next to me. He slipped his hands between both our legs and began stroking our wet pussies. His fingers felt so nice and judging by the moans from her she was enjoying them too. We  kissed whilst he fingered us.   It was sexy to have him doing that.   Before long we were both squirming and getting close to cumming. She came first. I watched as her body arched and she silently screamed as her body was rocked by orgasm. Watching her cumming made me cum and I joined her. My body arched off the bed as intense unbearable pleasure shot through me. Once it had died down we laid there and snuggled up to each other, both being rocked by aftershocks. He leaned down and thanked us for his present and went off for a shower. Later on we were  in bed and he told me he now knew how I felt as I had it done to me. Having two girls pleasure him and being able to pleasure two girls at the same time, not to mention twins was the best thing ever. I know I enjoyed it ;)
