“Is your penis as big as granddad’s?” Lucy asked calmly. “I’ve often wondered.” She realised that she had said too much and hesitated before she let me in on her secret. “It’s not the first time I’ve seen granddad’s penis.” Without warning she placed her hand on my crotch. “Your’s feels big just like his.”
Spreading my legs I allowed my sister to feel my hardening penis and I pushed my hand onto her pubic mound. Moving her legs apart she allowed me to explore her mons.
She unbuckled my belt, unzipped my trousers and pulled my pants down releasing my cock. Running her fingers gently over the tip of my penis then along its shaft she finally cupped my balls in her hand.
I pulled my shirt over my head and dropped it onto the floor. I was naked. My penis was solid and lay flat against my stomach.
Putting my hands underneath her skirt I moved along her bare thigh stopping at her knickers. Our lips met in a soft and gentle kiss while I fingered her vaginal lips through her panties. “You can take them off me.” She said.
Lucy held my cock in her small hands while I pulled her knickers down her legs and flicked them aside. I rubbed her breasts with one hand and put my other onto her back to undo the clip. “It unhooks in the front.” Lucy said.
Lucy unclipped her bra. Her breasts looked fantastic just like our grandmother’s breasts did in the pictures.
“Your penis looks just like granddad’s.”
Moving my sister’s legs apart I knelt in front of her and ran my tongue along her opening while she fingered her clitoris. I moved her fingers away and kissed her clitoris before playing my tongue on it. After a while Lucy gasped. “You’re good. You’ve done this before haven’t you.”
“Shell we go into the bedroom and fuck?” I looked up and saw that she was her covered in sweat.
“Yes.”

We went into the bedroom and fell onto my bed. Lucy guided my penis up and down her slick opening. We kissed for the second time. This time a hard open mouthed sexy kiss. She was so wet down there that when we moved my penis slipped into her. She did not try to stop me entering her.
We were fucking bareback.
Her vagina tightened on my penis. Putting her arms around me she held me tight and pushed herself down onto my penis. With our bodies pressed firmly together I pushed up and my penis moved deeper inside her.
With each stroke I went deeper. I came first and Lucy immediately after. My penis became soft but was still big and I kept moving it gently in and out of her.
“Thank you that was wonderful. That’s the deepest my penis has ever been inside anyone. Weren’t you worried?” I asked.
“No. I’ve taken a big penis before?” We looked at each other and I suddenly realised who’s penis it was.
“Granddad?” I asked and stopped moving. My penis slipped out of her.
Putting my fingers onto her vaginal lips I collected my cum that was oozing out of her and I took my cum covered fingers up to her mouth. She licked them and guided my penis back into her vagina.
“I’ve just fucked my brother.”
