After aunt Dorothy told me that uncle Ron was actually my father I was stunned, but looking at the photo of him when he was my age I totally believed her, the likeness between us was unmistakable.
"So, I'm actually having sex with my step mum?" I asked.
"Yes Paul, I'm so sorry that you had to find out the truth like this, but once we started having sex I was hooked and I've fallen in love with you. I understand if you want to end it but I'm happy to carry on seeing you."
"Your mum and Uncle Ron had an illicit affair for a few months until your Dad discovered them together. There was a massive fallout about it but over many years we all forgave each other, it was obvious that Ron had made your mum pregnant because your dad had a vasectomy after they had their second baby."
I felt sick at learning this, but I really loved my Dad and he will always be my dad, that will never change.
"I don't want to stop seeing you, I want to be with you forever." I said.
"That's great, I feel the same, but let's keep it secret for now, people won't understand us being together so soon after Ron's death." Replied Aunt Dorothy.
As I looked at Aunt Dorothy a feeling of extreme lust came over me, I wanted her now. I grabbed her arse and kissed her, I pulled her tight to my body and rubbed my ever hardening cock against her pussy. "Fuck me right here" Said Aunt Dorothy.
She lifted her dress up around her waist and I dropped my pants around my ankles, she bent over the back of the sofa and offered herself to me, I slid her panties down and they fell to her ankles where she took one foot out of them, I dropped to my knees then parted her arse cheeks and breathed in her pussy and arse aroma.
I licked her arse hole and put the tip of my tongue just inside causing her to gasp.
"Ooh that's nice" she said.
I moved my tongue down into her open pussy and it was soaking with her juices. I lapped up her beautiful sweet juices then stood up, I rubbed my cock up and down the length of her wet slit coating my cock in her juices, I teasingly placed the head of my cock at the entrance to her arse and pushed very gently, "not there baby, put it in my pussy."
I moved the head of my cock to her gaping pussy and shoved it all the way into her, slowly I fucked her wet hole and then felt her fingers touching my balls each time I buried it deep inside her, she rubbed furiously at her clit as I continued thrusting in her, "I'm going to cum." I said.
"Me too."
I pulled out of her and rested my cock between her arse cheeks as it pulsated and emptied it's load between her cheeks, my cum dripped down her arse and onto her pussy. As aunt Dorothy rubbed her clit I inserted the head of my cum covered cock just inside her arse hole and felt her pussy throbbing as she came too.
