Getting it on with my sister.
Mom was very eager over the next few days, but Gran managed to outdo her. I fucked them both eagerly, but I wanted to make mum pregnant and Gran was sapping my strength. These last few days had been very tiring, waking up with my cock in Gran’s mouth making me hard and then getting me to fuck her. She was insatiable. Mom was not much better, expecting me to give it to her whenever she felt like it. I had to have a rest. I told them both that I would be too tired to fuck if they carried on as they did so we worked out a rota. Mom was Monday Wednesday and Friday, Gran was Tuesday, Thursday and Saturday and Sunday was a day of rest. I didn’t mind too much but three times a day, for six days sure made my cock sore. Mom kept mentioning my sister and how we should be planning on getting the stuck-up cow to be part of the proceedings. I told her that at the rate we were going there would be little to no chance of me having the strength to fuck my sister.
Strangely enough it came about by sheer chance. Mom and Gran had left for some shopping after both of them had completely drained me on a day that should have been Mom but Gran had to join in. While I was reaming Mom’s cunt, Gran was rubbing her oozing quim over my face and screaming for me to stick my tongue into her hole. Of course I complied and after about five minutes of this, she released her cum over my lapping tongue with a squeal. It ran down my chin and dripped onto my chest, forming a pool. Mom immediately leant forward and licked it up and as she did I felt her muscles contract round my cock causing me to erupt inside her.
She lay on top of me and Gran stood up. I looked up to see her wide-open hole and a drip of cum slid out and dropped on my nose. Mom began to laugh and my cock slid out making a popping sound that made us all get the giggles. When Gran was laughing her tits began to wobble and this made us all worse. After we had got over our fit of the giggles Mom and Gran took a shower together and I lay watching them clean each other. I hid my growing erection from them with a pillow as I didn’t really feel like going another round at that particular Moment.
After they had dressed and left for the shops I fell asleep on the bed but was awoken by the door slamming and my sister storming up the stairs. I quickly leapt out of bed and pushed Mom’s bedroom door closed.
Sis stomped past and went into her own bedroom. I noticed the
light on the phone come on and soon heard her shouting. I could tell by the conversation that it was her boyfriend that she was shouting at and I caught the words “You bastard, you are a pervert,” and then I heard the phone slam down. As I listened I could hear her sobbing so I came out of Mom’s room and entered her bedroom.
“What’s the matter sis?” I enquired.
She answered through her sobbing “I can’t tell you it as too disgusting.”
I kept on at her and eventually the story came out. I had told her that it would make her feel better if she told someone else and assured her that whatever it was it would go no further than the two of us.
As she began to tell me I began to massage her shoulders lightly and the story unfolded.
She had been at her boyfriend’s house and they were smooching on the bed.
He had got her to agree to a quick fuck and they had both stripped off.
I was a little shocked at this as I was sure that she was a virgin and a sex hater. Obviously I was wrong as she continued her story.
“We were making love when he asked me to turn over so we could do it doggie fashion. When I was in position he slid into me and I was enjoying it immensely…”
As she spoke my hands went lower on her back and then under her arms to lightly caress the sides of her breasts. She didn’t seem to notice as she continued her story.
“He pulled his cock out of me and the next thing I know he is forcing it into my ass. I couldn’t get away because of the position I was in and he must have got more than four inches in before I managed to buck him off of me. I told him that he was a pervert and getting dressed I came home. I never want to see him again, the dirty bastard.”
My hands were now cupping her breasts and still she did not push me away. I noticed her breathing had increased slightly and her eyes were closed. It was now or never, Kissing her on the neck, I lifted her blouse and slipped her bra up so her tits were sticking out underneath.
My hands began to knead her breasts and I tweaked her nipples until they became like hard little acorns. She moaned slightly but other than that, let me continue. I walk in front of her and pulled her to her feet. It was if she was in a dream as I kissed her on the lips. Her mouth opened to accept my tongue and we kissed for about a minute while all the time I massaged her butt. I lifted her skirt until it was at waist height and put my hands back on her panty clad ass. She was still moaning as my hand slid under her crotch to run along her covered cunt. It was wet.
Sliding my fingers into her gusset I found a pair of thick swollen lips, very wet and open. My finger slid into her hole and she pushed down. All this time neither of us had spoken and the silence was only broken by our heavy breathing and her moans.
My cock was hard and as I unzipped my pants with my other hand, I was shocked to feel her help me and as soon as it was free she grabbed hold of it. I broke the silence.
“Oh sis, that feels gorgeous…”
My finger was rapidly sliding in and out of her spasming cunt producing load moans and wet slurping noises.
Suddenly she pushed me away and ran to her bed throwing herself down onto it and making sure her skirt was over her waist. I immediately moved over and got on top of her and pulling the gusset of her panties to one side, positioned my cock at her waiting hole. Still nothing was said as I slid into her. She was tight compared to Mom and gran and I could feel her cunt muscles gripping my shaft as I slid my full seven inches into her. She moaned and for the first time since this had started she spoke.
“Fuck me little brother, ream my cunt with that big fat cock of yours.”
I felt proud. I knew my cock was not anything special size wise but I also knew that, with the practice I had had with Mom and gran, I knew how to satisfy a woman. I slowly fucked my sister into orgasm after orgasm. I thought that Mom and Gran came a lot, but it pissed out of my sister. I could feel her juices squelching on my balls as I slid in and out of her. Her lags were wrapped round my waist as I fucked her, forcing me in as hard as she could on every inward stroke. She was shouting and moaning as I came in her. Jet after jet of hot spunk entered her womb and I imagined my sperm swimming towards her fertile eggs.
“That’s right son, fuck her good, make the stuck-up bitch pregnant.”
I glanced over my shoulder to see Mom and Gran standing in the doorway.
