Series on OTGC: Sealed with a Dick Caps

"I don't know. I guess I got a little carried away at the mall."

"A little?" My step-sister Katie looked at me warily. She moved into my flat after college and has spent most of the time lounging around and not finding a job.

"Tsk. But there were soooo many cute outfits. I couldn't just stop at buying a bathing suit. Especially when I have a body like this."

My sister sighed. "Brandon, you should have gone to the doctor, not the shopping mall. There still may be a chance to reverse the pill."

"But Mike invited me to the pool and it's soooo sunny outside!"

"He's also came inside of you like an idiot and locked you in that body. You need to get yourself under control. This is your life we are talking about."

I sighed and looked at my bags. "I know. But, I trust Mike. He was the only person I could count on to make my first time comfortable and safe."

My sister laughed. "Well, he sure did a great job." She grabbed my shirt.

"I mean, geez!" Katie grabbed my blouse and pulled. "These tits are huge. What ChangePill did you even order, the bimbo model?"

"Ha! Mike says a bimbo is just a girl who knows she's beautiful." Katie rolled her eyes. "And I like completely agree with him to be honest. I mean, wouldn't you love to have tits like these?"

"No! I like my tits."

I rolled my eyes. "Yeah, what's so great about them?"

Her face was priceless. "Figures, one day a woman and you're already a total bitch!"

I crossed my legs on the couch. "You still haven't answered my question."

My sister scoffed and put her head down. I could tell she was a little intimidated by my new form and part of me wanted to reach out and let her know everything was okay. But I stayed still and waited. When she started to unbutton her flannel it felt like a challenge. I knew I should tell her to stop but I let her continue until she stretched her arms wide to let it fall from her shoulders.

"They're not bad, sis. Not bad at all." She smiled slightly as I took off my blouse.

"To be honest yours are much bigger. I always wondered what tits that big could feel like. Are they heavy?"

I nodded. "More than you could imagine. The way my bra holds them makes them feel even more substantia - I mean, like BIGGER. They feel like they have minds of their own. Like they need to be reigned in or else - "

"Or else they'd bounce everywhere and smack you in the face!"

We laughed.

She grew quiet. "You're really liking this aren't you?"

"I. . . I'm not sure. I mean, I'm so totally going to try to change back. I mean really. I can't be a woman forever. That would be like sooo weird. . . "

"Are you sure?"

"Yes, I even promised to myself I wouldn't, like, fuck anymore. Just to make sure I don't go too far down the rabbit hole. Having a dick in my pussy again would be too much."

"Okay. Sure. . . But are you sure you can keep your hands off Mike? Doesn't part of you want to be fucked again to see if it's better the second time?"

Her questions were making me nervous. For some reason whenever I was nervous I wanted to babble on to cover my anxiousness - and the silence. "Absolutely! I'm going to hop my tush into my bathingsuit, hang out with Mike in the sun, and then I'll go straight to the urgent care and get everything taken care of. All of this is just a little diversion. When I change back I'll take all of this stuff back and go back to being your big brother!"

She nodded again, sheepishly looking at my tits again. "If you say so, big brother" She looked down at my skirt. "So. . . Is your pussy nice?"

My eyes widened. "Y-yes. . . it's nice." My brain was foggy. "And it's tight. So tight I'm almost jealous of Mike." We had never talked so openly about our bodies before. I thought maybe I should stop, but instead I asked: "What about yours?"

She swallowed. "Well, big sister. You'd have to take my shorts off and see for yourself."

She motioned with her eyes down towards her crotch. Her words rang in my ear. "Big Sister." I could feel the nothingness between my thighs. I was her big sister; at least for a little while longer. The realization sent tingles into my pussy.

What was happening? Was my step sister actually attracted to me? I couldn't think straight. For some reason all I could do was reach towards her shorts and unbutton them. I totally needed to see it. I needed to compare it to mine. I grabbed her panties along with the waist of her shorts and pulled everything towards me.

"It's beautiful."

"I thought you'd like it." She smiled for a moment, fingering its countours lightly before getting on her hands and knees and leaping towards me.

"Katie! What are you doing?"

"I'm taking your skirt off. I've shown you mine, now show me yours. You have time to play before going to Mike's don't you? I mean - we should, right? Since you are going to change back afterwards and all? Oh wow. Yours is so tight and delicious looking. I can't believe this is your body now. Please, sis, can my tongue have a taste of it? Please?! I want to see what my big sister tastes like!"

Oh fuck. I want her to see too. Is this really a good idea? I already resolved at the mall not to have any more sex. But would this even count? It's my step-sister. I mean, she is hot and we aren't even related or anything. I kind of like the way the curves of my body totally dwarf hers. Maybe if we just make out a second I can decide what to do.
