My sister Gina was a nymphomaniac, whether it was cock or pussy she lived to fuck, and loved to be used. I got dressed that morning fairly early, we were stopping at my Aunt Marie's and her life-partner Jessica's, and ended up spending the night. I didn't fancy either of them catching me in the bed my sister was sleeping in. But my sister was a temptress, and a quick ‘see you soon kiss' turned into eating her out 

 

 

 

An almighty crash punctured my ears. I turned to see my Aunt's shocked face, and the debris of breakfast across the floor. We were in big trouble, until Gina had an idea to buy her silence. "Use me Aunt Marie, I want to be used by you and my brother.". Marie didn't have a chance to answer, she already had my sister's tongue in her mouth. 

 

 

She agreed to participate, but told me to not even think I had a chance of fucking her. Marie and Jessica had been together ever since I was a small boy. We kissed some more, and to my suprise they both sucked on my dick. My mind was asking so many questions; ‘When was her last time?', ‘Does Jessica fuck her with a strapon?','Am I her first?!'. As my thoughts raced, I was on my back, inside my sister, her body being groped and kissed by my Aunt. 

 

 

"Oh go on then" My Aunt muttered, I was confused what it meant until she was there bent over on the couch. I'm pretty sure my cock grew an extra inch as I stood behind her, I grabbed her by the waist then slid inside her wet lesbian pussy. It was magnificent, all three of us engrossed in each other's bodies, it had an element of danger, exploration, intense excitement, and unspoken taboo. 

 

 I felt oddly proud of myself when they were both in the pile, slaves to my throbbing cock. The dynamics of all our relationships had changed, I'm sure I could fuck my Aunt without my sister, but I'd like her to be there to enjoy this experience once more. We had two more nights left here, surely it wouldn't end right here.
