I had worked most of the weekend, filling lots of my free time laying on my bed masturbating over my thoughts of Mary - thinking of what we had done and allowing my thoughts to speculate on what we may yet do. My capacity to produce more and more spunk seemed unlimited.
Whatever was going to happen after the summer break ended, I knew that what I felt for Mary would not change. I knew it was wrong to have such strong, romantic and erotic feelings for my own sister but I didn't care. I loved her in a way that no brother can legally love his sister. I believed she felt the same way about me. So whatever happened I knew I had to find a way for this to continue into the future.
A lot easier said than done!
Nevertheless, the new week dawned and I was in a very happy place. My work shifts were not too bad this week - I had most mornings off, working afternoons and evenings only except for Friday when I had only an evening shift and so had the day free. And the weather had cleared over the weekend and we were back to warm, sunny days. All looked bright for this next week.
After mother had left for work on Monday I heard Mary's door open and the sound of her footsteps as she walked through to the bathroom. After hearing the toilet flush I heard the shower start and so got up to follow her. I walked into the bathroom and greeted her. "Hi babes - how's things?" I heard her laugh with pleasure. "I'm great" she said. "Why don't you get in here with me so we can take a shower together. It will save some water."
I agreed without hesitation. After brushing my teeth and having a quick shave I climbed into the tub and stood watching Mary as she soaped her body all over, making a great show of lifting each of her breasts and soaping underneath and then pushing the sponge between her legs and cleaning along her pussy and between her wonderful arse cheeks. Mary's hair was tied up in a spray on top of her head and, without any makeup, she looked almost innocent.
Mary reached over and picked up the shaving gel and worked it into a lather which she spread over her legs. I had never imagined that watching a girl shaving her legs could be so exciting!
Once she had done her legs, Mary then lathered her pubes and her groin. My throat was dry as I watched her shaving around her pussy, clearing away the traces of stubble that had grown over the weekend. She looked at me watching her. "It needs to be done regularly or else it gets itchy" she said. "And I don't want it be rough across your tongue and face." She smiled broadly as she said that last bit and I found it hard to swallow, such was my excitement.
She finished and washed away the remnants of the foam and turned off the shower. She leant back against the wall and lifted one leg up onto the edge of the bath, causing the lips of her pussy to pull apart, revealing her inner lips. Her shaved pussy looked magnificent and I sunk to my knees in front of her, grabbing the cheeks of her butt and pulling her hips towards me.
I stuck my tongue out as she started to grind her pussy on my face. I tasted her juices starting to drip on my lips, as I took her clit into my mouth and sucked on it. "Aaaahhhh" Mary groaned as I probed her cunt with my tongue and licked over her clitty. I pushed gently against her thighs and got her to turn around and lean forward against the wall. She raised her leg again to the side of the bath and I pushed my head between her thighs and continued to slurp up and along her pussy lips from behind.
As I worked on her cunt, I could feel my nose press tight against her arsehole. I slowly licked her along her pussy from her clit to her arse and, without conscious intent, started to probe her puckered rosebud with my tongue. She wiggled her hips and let out a moan. "Shit Adam, that feels so nice." I pushed my tongue harder and I felt her sphincter relax and my tongue probed into her arse.
My finger was rubbing across her clit as my tongue was fucking her arse. Her juices were flooding out of her pussy and I knew it wouldn't be long before she came on my face. My tongue left her arse and made its way back to her clit and I heard her moan with what sounded like disappointment at me abandoning her arse. Her moans of disappointment soon turned to whimpers of pleasure when I replaced my tongue with a finger slipping into the opening of her arse. I sucked her clit into my mouth as I probed deeper and deeper with my finger - fucking her arse with my finger while I was still sucking on her clit.
"Oh yes Adam," Mary moaned, "Please don't stop. I'm going to come. Please don't stop."
I increased the speed of my finger in and out of her arse and my tongue was lashing over her clitty. Suddenly I felt her juices squirt from her pussy and into my mouth and spreading over my face. Her hips were rocking back and forth, forcing my finger deeper into her rectum. "Oh God Adam, I'm, coming! That is soooo good!"
Mary was grinding her arse onto my finger as she came all over my face, her sphincter was contracting tightly onto my finger as if she were milking it. The feel of her warm, fragrant juices covering my mouth and lips was divine. Mary finally subsided and wiggled her arse off my finger and her body was shaking with tremors that still flowed through her. "Oh my God, Adam, that was amazing" she gasped. She turned to me and we kissed passionately, running our hands over each other's body. We clasped each other tight for a while and I could feel her heart beating like a drum through her chest.
Mary pushed away from me, climbed out of the tub and held a towel up to her chest, leaving her lush behind bare for me to stare at. "Come with me - let's go to my room" she said. And opened the door. I quickly got out of the tub and grabbed my own towel and followed her.
I couldn't help but stare at her arse, watching those fantastic buttocks swaying and jiggling as she walked. Mary glanced back over her shoulder and giggled. "Do you like what you see?" she said. "Don't you get tired of looking at my butt?"
"Never!" I replied. "How could I ever grow tired of watching your arse? I love watching every part of you. Your body is the most beautiful there is!"
Mary laughed again and gave her round behind a little shake. "It's all yours, brother dear."
Walking into her room she dropped her towel and leant forwards so that her butt was sticking out and I could see the outline of her pussy peeping from between her legs. She turned her head to look at me and, seeing my bulging eyes and my open mouth, she laughed. "You really do like it, don't you?" she said. "It makes me so excited to see you looking at me like that!"
Mary stood up and walked to me and draped her arms over my shoulders and rubbed her breasts against my chest. She leaned her head forward and started to kiss me hard on the lips, probing her tongue deep into my mouth as she sucked on my lips.
Pulling away she pushed me so that I lay back on her bed, with my feet on the floor. She knelt in front of me and took hold of my swollen cock and kissed the head, licking her tongue over it to suck up the pre-cum that was already oozing out.
She licked my cock from the bottom of the shaft right to the top and around the head, and then all the way back down again. I could feel her warm breath on my balls. Stroking my cock with her hand Mary gently took first one of my balls and then the other into her warm mouth. She rolled my balls around on her tongue and gently sucked on them. At one stage she opened her mouth wide and forced in both balls at once and it was almost too much to take. "Ooooh, mmmm..." I groaned as my spunk built up and started to clamour for release.
Releasing my balls Mary let her tongue travel slowly down underneath my balls and toward my arse. I almost exploded when her tongue slurped over my arse and around my sphincter. She gently wiggled her tongue around my arsehole and started to probe at the opening. "UUrgh..." I groaned. The feeling of her warm, wet tongue rimming my arsehole while her hand pumped my cock was too much for me.
"Mary, That's soooo good. I'm going to come" I shouted.
"Come on my baby. Come for me my darling" Mary said as she doubled her efforts, still pumping my cock with her hand and forcing her tongue right into my arse. The feeling was so intense I couldn't stop and I felt my spunk shoot up my engorged shaft like a cannon.
