Becoming My Sister

Chapter 4

It felt like I was in a trance as I climbed into my sister's bed with her gorgeous boyfriend. I knew what I had just done and could still taste his cum in my mouth. I could feel the conflict in my mind. The 'male' part of my brain fighting against what I had just done but the 'female' part of my brain was winning, was dominating, my thoughts. All the hours spent dreaming of being my beautiful sister, wishing more than anything that I could be her...it could not be denied. I giggled just like my sister did and pushed my long blonde hair over my ear just like she did as I smiled at him and joined him in her bed.

Despite being more turned on than I'd ever been before, incredibly my dick was limp and seemed to shrivel and shrink. No tenting of the panties which always happened when I was alone! Maybe it was because I felt sooooo feminine and my brain was now thinking 'I'm a girl and girls can't tent panties like guys'. I think this feeling was reinforced by the fact that I was freshly smooth just like my sister, and all her friends. It seemed to me like every girl in the world says was completely bald because it's what guys had seen in porn films and therefore expected the girls they dated to be the same. I certainly found it a turn on! Because it felt and looked like there was nothing beneath my panties therefore it couldn't be 'me' but must have been 'Aimee' in bed with her boyfriend.

He took me in his strong arms and held my slim smooth slender fragile hairless frame against his big strong muscled body and kissed me deeply. I moaned with pleasure as I felt his strong fingers exploring me, caressing me, stroking me as his big thick dick grew and pressed against me. We breathed in deeply reveling in each others scent as we made out, his rock hard dick rubbing on my soft smooth skin, my false red nails gently digging into his muscled body as I dragged them slowly over him, causing his back to arch with pleasure...dragging the heel of my shoe over his calf, using everything at my disposal to give him one pleasurable sensation after another.

His moans told me I was doing all the right things and I was amazed at how easily I had fallen into the female role, how I seemed to know exactly how to please a man, how to react to what he liked and what he liked less. Well, it was because I was a 'man' and this is how I'd fantasised a girl would act for me in bed...my whole focus was on turning him on and pleasing him just like in porn films.

But at the back of my mind there was always a hint of panic around how I looked. Did he like my hair? How was my makeup looking? Was my lipstick smeared all over my face making me look like a clown? When he breathed in deeply did he like my perfume? Were the heels I was wearing high enough? Was my jewellery too subtle or too bling? I knew I had no breasts and did he wish he was with a 'bigger' girl? Did he think I was fat? I must go on a diet. Is this what my sister and every other girl thought? I knew the pressure on girls to be perfect was drilled into them by society, social media and their friends. I know a lot of girls crumbled undo that pressure but to me it was the most wonderful thing as I wanted to be perfect for a guy. If pressure came from every side to make me perfect then I decided I wouldn't fight it but embrace it.

I slowly started to kiss and lick his chest, loving the feeling of his fingers playing with my long blonde hair as I moved down...over his abs until his beautiful dick was inches from my mouth. I breathed all over it and then began to kiss, lick and then gently suck his smooth balls hoping they were full of his cum again. He moaned with pleasure as I dragged my tongue slowly up and down his shaft, tracing the tip over the thick veins which stood out, my fingers gently holding the purple head, feeling the precum oozing from it.

I made sure I looked up into his eyes as I wanted him to see just how much I was loving this. I wanted him to appreciate the effort I'd made to look perfect for him. Just a small compliment was all I needed. Just affirmation that he noticed was all I craved. I wanted him to look at my makeup, to look at my glossy red lips, my big blue eyes, my long nails. I wanted him to think I was pretty and feminine and submissive to him. He moaned with pleasure as I fluttered my eye lashes up and down his shaft giving him 'butterfly kisses' and I made a mental note to get some long false eye lashes for next time...oh god, I so hoped there would be a 'next time'.

"I think you're even prettier than your frigid sister," he moaned as my lips slid slowly up and down his beautiful dick.

"She's frigid?" I asked breathlessly and giggled.

"Fuck, yes! She may be the hottest girl in town but she will do jack shit in the sack. She has never even given me a blow job," he complained bitterly. This was music to my ears and I loved that I was doing things better than her...for probably the first time in my life.

"You like the way I suck?" I asked hesitantly as my mouth slid down, taking him as deep as I could. His moans of pleasure, his fingers holding my head in place and the slight buck of his hips as saliva streamed from my mouth gave me the only answer I both needed and wanted.
