Three days after my seventeenth birthday, and eight weeks after my mom and dad split up, Neil invited me round to collect my present. What I didn't know, was my sister had been round the day before to collect hers. Sat in his lounge Neil walked in with my drink he'd offered me, wearing only his flip flops. His massive cock was semi hard and I couldn't help staring at it. He gave me my drink and then said "This is yours if you want it". He paused before he added "I've noticed you watching me and this for some time, so if you'd like to have some fun, I'm and it's all yours for today".
I couldn't get his cock in my mouth quick enough. It had been my desire for so long, or so it seemed and there it was ready for me to enjoy. And enjoy it I did. I spent the next quater of an hour giving my uncle all kinds of pleasure with my mouth and tongue. His wasn't the first cock I'd sucked, but it was by some margin the biggest. And knowing he was enjoying what I was doing for him, made me enjoy the whole experience until he came flooding my mouth with his cum, all the hornier.
With his salty cum filling my mouth, he asked me if he could tongue me. Taking of my skirt and panties but leaving on my top, I lay on his couch and spread my legs. Neil gave me such an amazing tonguing, I found myself cumming four times. The first time I'd ever orgasmed that many times in a row. After my final climax, I asked him if he'd fuck me as I was desperate tro feel his cock inside of me. But Neil told me he wouldn't fuck me until I turned eighteen.
It was a very long, yet sexually satisfying year. My sister and I without knowing for some time fell in love with Neil, and his wonderful way of teasing out many many orgasms with his masterful tongue. And every time I gave him head, he'd give me such quantities of cum, I found myself gulping down what seemed like gallons.
Throughout it all and up to finding out about each other, my sister and I grew very close, but neither of us told about the other. Then my sister got a cold, a bad cold and didn't go over to Neil's when they'd arranged. Thinking she'd miss their weekly sex session, Neil text me and asked me to call by after college. I was sucking in his huge cock when my sister walked in.
It might be that we are twins, or that we went through such tough times with our parents splitting up, but my sister didn't react as maybe you might think. Instead of shouting about Neil being her lover, my sister said "Move over girl, let me get some of that". Neil's response was to say "Thank fuck for that, now I don't have to hide one from the other".
Over the next half an hour with my sister stripping naked as I was, we both pleasured our uncles cock and had him tongue us both to orgasm, as we took turns to sit on his face. Then with my uncle having his cock sucked by my sister, I looked at her freshly climaxed pussy and couldn't resist putting my mouth down to her wetness. In all our time growing up, we'd not once touched each other sexually, so when my tongue lapped up and down her wet slit, I thought she might tell me to stop. Instead she held my face to her pussy and encouraged me to give her cunnilingus. No sooner than Neil had cum in her mouth, my sister had a violent orgasm soaking my face with her juices.
Totally sexed out, we all lay naked and then looking at one another began to laugh. Neil went on to tell each of us about the other, and also added he hadn't fucked either. It was such a relief in a way, knowing the taboo surrounding Neil's and my sexual encounters, were out. And out with someone who loved me dearly.
For the next four months my sister and I met up at Neil's home and had sex as a threesome. Each week we'd stay at one of our parents home and then couldn't wait to have sex together. My sister and I also started to have sex alone without Neil. It wasn't as intense, but a more loving type of sex. Kissing more, stroking each other more and definitely more gentler oral sex.
Then three weeks off a year ago, Neil invited us both over to collect our "Birthday present". Watching his cock bury itself up my sisters pussy will saty with me forever. They fucked and fucked until he had my sister screaming with delight from a huge orgasm. With her settling down, I mounted my uncles pussy juice covered cock and rode him as you might see a guy riding a rodeo horse. It was such a thrilling fuck, I kind of forgot for a while my sister was right there watching me take Neil's large cock up my pussy. It was my turn to cum as Neil had had me get into the doggy position. As soon as he moved us around, my sister got infront of me, opened her legs and asked me to tongue her. When I orgasmed from Neil's forceful fucking, I also brought my sister to climax and had her bucking in my face.
We stayed having sex together for another two hours, with my sister becoming more of the dominant person in regards to us. Neil took his sweet time pleasuring us both with his massive cock, and only afterwards did I discover he'd taken a little blue pill to give a birthday present to remember.
This past year has been hard with regards to my parents, as it's been a messy divorce to say the least. But Neil and my sister have been rocks to me. Both in a family way and of course sexually.
If and when I eventually move on from fucking Neil (Not planning to quite yet, as he's too good in bed), and find a man to marry. I don't think I'll ever stop having our time together, as sister and sister lovers.
