I am in a unique/weird relationship, am Bi who`s in open relationship with nice & loving guy Dan , his sister Sarah is also Bi , she and I have been intimate on several occasions , since there`s no secrets between Sarah and me , she confessed that during her teens she and Dan got naughty, except for Vagina sex brother & sister did everything sexual ,even today both of them are very close to each other

It was lazy Sunday morning I was at Dan`s place, we had some incredible sex on Saturday night , he was resting on the sofa while I was watching TV and fondling his cock, the doorbell rang and it was Sarah, she said she was in the neighbourhood and just wanted to say Hi to us,I made coffee for Sarah and myself , Dan was still lying on the sofa, Sarah got engrossed in watching TV, Dan too my hand and placed it on his cock, in other words he wanted me to keep on fondling

Dan was just in his boxers, my fondling graduated into stroking which made Dan`s cock hard and throbbing , all this time Sarah was watching and smiling , I wanted to test the water, I pulled out Dan`s boxers and began to suck his erect cock ,as I was sucking my eyes met Sarah`s, I winked at her , she got up and knelt near me, without a word she grabbed her brothers cock and pulled it out from my mouth and took in her mouth, since there was not element jealousy , we sucked him in turns

Dan was shaking an shuddering, whimpered that he`s going to cum any moment , Sarah pleaded me to let him cum in her mouth, I had no problem with this , Sarah began to suck him ferociously while I licked Dan`s balls , with muffled moans Dan came in Sarah`s mouth, she swallowed every drop of his cum, thereafter I milked his cock for the remaining and ended with French kissing Sarah

Had a memorable Sunday
