No, he decided to mess with Nadine.

I didn’t really need to lie down. Instead, I headed into my room and stripped again, activating my power.

Seeing Nadine, all dressed up in her tight-fitting business wear, had gotten me wondering about exactly what I would be able to do with my newfound power. Obviously, I planned to use it to start making me money, but for now, as I had been told to take it easy, I planned on having a little fun with it. Tomorrow was for business, today I was more focused on pleasure.

I gently opened my door, scanning the hallway to make sure that Amy was not lurking around. With the coast clear I headed towards Nadine’s door. It was closed, no surprise there, and I placed my ear against it, listening for the tell-tale signs that her shower was running.

I could hear the pitter patter of water hitting glass, she’d already gotten in. Now was my chance. I opened the door as silently as possible and snuck into the room, closing it behind me.

Nadine’s room was much bigger than my own, with closets and clothing racks running all along the walls. Her bed had light grey silk sheets and was left unmade, and to the right of it was the door leading to her ensuite bathroom. Steam already gushed out of the open door, and I felt my excitement increase when I saw, on the floor, the discarded blouse and skirt that she had been wearing when she got home. Next to them was a matching bra and panty set, and some tights.

My dick was as hard as steel. In all the years that we had lived together I had never been able to sneak even a quick peek at my older sister naked.

I cautiously creeped towards the open door, seeing, behind fogged glass, my sister soaping her full breasts. Despite their large size they were still incredibly perky and seemed to defy gravity as she moved around inside the shower.

I moved into the room, thankful that her shower room was much larger than mine, taking position just in front of the glass sliding door of Nadine’s shower. The steam whirled around me as I tried to think about my next move. In front of me, Nadine was putting on a show that would turn most men into unthinking wrecks. Her hand snaked sinuously around her body as she washed herself. On a shelf, to my right as I faced the door, her shampoo bottle sat next to her razor.

Thinking quickly despite the distraction, I realised that she would have to open the door to grab the bottle. Hopefully, if I was the luckiest man alive, she would leave the door open.

I stroked my cock, feeling it throb in my palm. Was this another side effect of the jab? I rarely needed to cum this much normally, and usually after fapping for a second time I would need to recharge for a few hours.

Nadine opened the door, reaching out to grab the bottle with one hand and giving me a mental image that I will never forget. Her curvy body glistened with the wetness of the shower, her nipples were dark and hard, begging to be sucked. I was pleased to see that she was completely shaven, and I could even see that her large clit jutted out ever so slightly from her open slit.

My cock ached and I knew I had to do something to relieve it. She left the door to the shower completely open and a light spray bouncing from her body and onto me as she turned her back to face the shower head.

Nadine began wetting her hair, letting the hot water cascade off the top of her head as she squeezed the shampoo out of the bottle. I watched, in awe of her perfect porcelain skin and sexy curves, as she lathered her hair for what felt like hours. When she was satisfied, she took the nozzle of the shower out of its holder and bent forward, giving me an amazing view of both of her holes as she began washing the lather off.

I made a decision. I moved forward, grabbing my throbbing cock in one hand and steadying myself with the other, and began wanking it vigorously as it pointed at her hairless cunt. I imagined impaling her with it, hearing her gasp in surprise as my invisible cock filled every square inch of her tight little hole.

I felt like I was standing there for ages, but she kept washing the lather off so it couldn’t have been for too long. I felt my orgasm coming as my balls tightened and I pointed my convulsing cock right at her hairless slit. My cum erupted like a geyser, spraying her pussy and upper back with my hot load. She didn’t even notice, I guess because the hot shower water was falling on her back, and I watched in a post-orgasmic stupor as she straightened up and my load began sliding down her legs and ass.

She turned to face the open door, and once again I was left with a mental picture that would last me a lifetime. My older, uptight, bitchy sister, standing like Venus as my cum slid out from between her milky thighs.

She stood there for a moment, clearly enjoying the hot water streaming over her back, and then she began tweaking and pulling her nipples. I watched, mesmerised by the show, as her right hand slipped down her body and parted her pussy lips and she began rubbing her clit.

The mere thought of her rubbing my cum into her pussy had me excited again. Although my cock definitely needed a break, the image was amazing. She rubbed herself, gently at first, as she tweaked her left nipple with her left hand. Light moans began escaping from her plum-colored lips as she picked up her pace, and her left hand moved along her body and began thrusting two fingers deep into her now slippery hole.

Holy fucking shit. Holy fucking shit. When I get out of here I’m going to need to make sure she is on birth control. My brain was enraptured with the thought of her impregnating herself with my seed, but, I knew for a fact that there were ways to tell if a baby was born from ****, and I definitely was not going to be getting myself caught.

I watched her finish, her moans building into a crescendo of pleasure as I wished I could be the one to give it to her.

A satisfied smile crossed her face as she turned to face the shower nozzle again, and I took this as my opportunity to slip into her room and check to see if she had birth control.

I snuck out of the room, being careful not to drip any of the steam onto her things as I looked around quickly. On her bedside cabinet I noticed a pill packet, and I rushed over to it to check its contents. Reclipsen. Bingo! Thank you, sex ed.

I tip toed out of the room, being careful to shut the door behind me, and headed back to my own.

I wished myself visible, positively shaking as I put my clothes back on, and then lay back on my bed and reviewed the events of the past few hours.
