Ive been with angie for 10 years. She's born in birmingham of Jamaican descent and has that lively Caribbean manner and is sexy without trying. As is her sister Jackie. Both beautiful, angie is tall, size 12 busty with that typical black woman's ass. Jackie is slightly shorter, maybe size 14 but it suits her and even bustier. Angie loves her sex but Jackie loves it even more. I know this because they are the closest sisters I've ever known and tell each other everything. Also Jackie will always answer Angie's calls no matter what and it's not been unusual for angie to cover the receiver and say to me "dirty bitch is only at it again". But then Jackie left her husband, he'd cheated, god knows how or why, and she'd come to stay with us. Which was great, I love being with them both and Jackie has seemed her usual sunny self. I'm a bit slow to catch on to the obvious, I'd heard a buzzing noise but couldn't work it out and one evening as angie and I lay in bed I heard it again and asked her if she knew what it was. She laughed thinking I was joking but then had to explain it was Jackie's vibrator and Jackie needed to use it several times a day now she had no man. That thought turned me on and I was soon emptying my balls into angie who came with me and at the same time the buzzing stopped so 3 mutual orgasms I guess! A few days later angie started a week of night shifts which meant no sex for me. But I was happily wanking at night to the buzzing and if I listened hard I could hear her whimpering too. One late afternoon me and Jackie watched tv as angie slept and Jackie excused herself and went upstairs. Sure enough buzzing. I couldn't help but take the chance to get an even closer listen and crept up to outside her door. I was delighted to hear sighs moans and even the slurp of her wet hole. I needed release and so slipped my cock thru my jeans fly hole. Quite suddenly the buzzing stopped and I heard footsteps and in a panic stuffed my cock away but as Jackie appeared at the door I hadn't zipped up and my crime was obvious. Red faced I whispered my apology but Jackie just beckoned me downstairs. I continued saying sorry but Jackie just said "it's really ok I don't mind. I have heard your bed springs at night so I knew you was wanking. It's natural Steve, it's only what I'm doing". My breathing calmed but soon increased again when she said urgently " but its not enough, I need cock". And I needed pussy so forgetting angie upstairs I re exposed my raging hard on. Jackie waved her hand "no no no not yours. Steve put it away. I couldn't do that to angie"" embarrassed again I stuffed my desperate member back in spilling pre cum down my jeans. Jackie then explained that she fancied my mate Chris who she knew was a bit of a player and could I arrange something. She said all it would be was sex, she was just craving cock. I rang Chris who couldn't believe his luck and invited her straight over. Well Jackie was in no mood to delay and as she doesn't drive I took her over and waited in the car stroking my aching cock as Chris gave Jackie what she needed. An hour later a much relieved relaxed looking Jackie got in the car. Her kiss of thanks on my cheek did nothing to subside my hot horny cock. She asked why I was driving so fast. I told her I needed to see angie before she left for work meaning I needed to deposit a hot load of cum in her cunt. Jackie phoned angie for me. This was the conversation. J- what time are you leaving? A- about 5 minutes, my lifts on its way. J- can you hold on Steve needs you for something. A- no I can't we 'll be going as soon as Rubina gets here. What's he need me for? J-(giggling) he needs your pussy. A- WHAT? J- you heard. A- no way I'm all showered for work. I put my foot down and arrived just as Rubina did. Jackie acting as my wingman asked Rubina inside for a second. Once inside I grabbed angie who tried to protest and I took her upstairs and into our room. "Steve we can't they'll hear" she said as I hooked her nurses dress above her waist and struggled to get my cock out. I pushed her against the wall and forced myself inside her thong. "There's no stopping you is there" she gasped as I went in dry. I answered "no I need to cum in you" "okay babe" she said " just try to be quiet" I fucked her harder than I ever have knocking over a lamp in the process and slamming her sexy black ass against the wall. I'm normally a quiet cummer but I yelled in absolute pleasure as this long pent up jism spurted into angie. "I'll take that to work with me" she said with the sexiest smile.
