Hubby fucked my sister with my permission and I can't stop masterbating to the thought of them fucking.

He had been through a rough divorce cause his ex wife was a cheating slut, we met through work and immediately hit it off, flirting at first which quickly turned in to him picking me up from work (we worked at different sites) and me blowing him in his car. Soon we were very much loved up and he was staying with me at my parents house, they all loved him, something about him being my protector and looking after me so well made them absolutely adore him, he met my sister after one of her drunken nights out and she came home very drunk and she started flirting with him. She w wearing a very slurry black dress which didn’t leave much to the imagination, she is much more well endowed in the boob region than me and I watched him peeking at her perky young tits. This went on for a while until I noticed he was rock hard in his shorts. I took him to bed didn’t mention the reason why he was so erect and blew him until he shot loads ( much more than usual). Of cum all over my face and tits.

Next morning he was already up and in the shower when I got downstairs, my sister was already on the sofa nursing a small hangover when she said to me, he’s awesome and I heard you to at it last night! I giggled and just said that his big dick needed some attention and I was a good gf and sucked him dry.

A little later I woke up from a nap to find them in the garden smoking and laughing, her hand constantly touching my bfs shoulder and arms. She’s always had a thing for big guys with tattoos and he’s got two full sleeves of beautiful artwork and very masculine strong arms. I watched for a minute as they flirted and I got a little wet thinking about them being so touchy.

Later in bed I asked him if he liked my sister and he coyly said yeah she’s cute and funny! I asked is he wanted to fuck her and he obviously said no but with a face full of ‘fuck yeah I do’ I told him I wanted him to fuck her on our bed while I’m waiting in her room listening to them to at it. He was shocked and thought it was a plan to catch him and chuck him out so dismissed me.

A few weeks go by of them flirting like crazy and my mum and dad went abroad on holiday so we were house sitting with my sister, I had an appointment (planned) on a day I knew they’d both be at home and I gave my sister the green light to flirt with him freely. She gave me all the details of what transpired when I returned. He was in the shower when she knocked at the door saying she was desperate for a wee, he let her in and she went to the toilet while he was finishing off. He finished and ce out to her sat in some tight booty shorts no bra and a very revealing almost see through top. She asked him if he’d ever been with anyone as young as her and they started to flirt, she told him she’d had a good peek at him in the shower and that I was a lucky woman to have him. To herself. She walked over to him and smacked him on the ass as she passed to go make lunch. She told me let out a little moan as she did and he watched her walk away, her young tight booty swaying as she went in to the kitchen.

I returned home to them sitting and chatting the air thick with atmosphere and I knew we were on! Later that evening I took him to bed but left the door open slightly, so she could hear him rail me fully. He fucked me harder and for longer than ever before! This time, for the first time leaving his cock in and filling me with his huge load.

Next morning sis told me she heard it all and even peeked through the door to see him bending me over and fucking the ass off of me!

It was on! Part two coming later….
