Ugggh, my head...

Why did I take that drink from Aversa?

Stupid, stupid stupid. I should have know better. Thraja was smiling when she said I could trust Aversa, and Tharja only smiles when we do something intimate, like hold hands or cuddle, or when she is about to do something abominable. We weren't holding hands.

My reverie was shattered by someone with very soft hands grabbing my hand. Probably Tharja. Pale-n-boingy is the second to last person I feel like talking to right now, but I can think of a lot of things she could do to make this up to me. She just needs to learn that “use both hands” does not mean “fist me with both hands at the same time.” That experiment with lesbian sex ended poorly. How can a dark mage as cruel as Tharja have so little imagination? How can she get off to cuddling and holding hands?I threw away my Chrom poster AND my Basilio poster for her, and th-

“She's ready for you, Robin.”

Oh, right, Tharja.

Fine, I'll open my eyes, but you better not be experimenting on Noire again. Last time it took two weeks to convince her eating unpeeled oranges would not give her blue hair.

I opened my eyes and saw Tharja staring down at me, holding my hand. And blushing of course. Unbelievable.

I sat up and realized we were in a tent I didn't recognize. Not mine, not Tharja's.

And then I saw her. My darling older sister Aversa, tied spread-eagle to a table with a gag in her mouth. Still dressed, not that her clothes left anything to the imagination. Still not sure what is going on here.

Before I could say anything, Tharja spoke again. “Look down.”

I did, and saw nothing out of the ordinary. Breasts still there, don't look any bigger. Still wearing my shirt and pants, only mildly surprising. Pants feel a little tighter than normal though.

Looking back to Tharja, she started blushing ever harder and preempted my question again. “Inside your pants.”

Oh Tharja, I wish you talked dirty like that all the time. Taking my pants off with Aversa so close seemed a little weird, but at this point I was too curious to care about brown-n-boingy. I fumbled with the buttons on the front of my pants, which were definitely tighter than normal, and discovered the surprise Tharja had left me.

I recognize that bulge! It's a penis! A large, erect penis. And testicles. A million thoughts raced through my mind as I stared at my new equipment in shock, some of them not even lewd.

“Tharja. 'Splain. Now.” I didn't even look at my girlfriend as I asked.

“I hope you like it. It's only temporary, but I can make the potion for you again.” Tharja's voice was tinged with something I had never expected from her: concern. It was oddly touching that she was worried I didn't like having a large penis, but she had somewhat missed the point.

“No, no, I love it, really, but why do I have it?”

“Your sister asked for my help in creating a potion that would turn you into a man. She thought you were the reason she has been unable to seduce Chrom. I agreed to help. She trusted me because she thought I would prefer you as a man.” Tharja paused to flash me her I-Love-You smile. Adorable. “But she miscalculated. She didn't understand our bond is deeper than that.”

I was touched. And horny.

Tharja clamped down on my hand and led me over to Aversa. “And now, she will pay” the original boingy witch declared before looking at me expectantly.

Even Chrom would understand what Tharja wanted me to do. And I wanted to, so very badly. Just being close to Aversa had pushed my meatpole to the breaking point. It took all my self control not to rip off Aversa's whore-rags and cover her in girlmanmilk.

Brutal rape is well beyond the moral event horizon for what Aversa tried to do, but then again...

Tharja went through all this trouble just so I could ravage Aversa with my magic cock. It would be rude not to, right? And this bitch needs to be taught a lesson anyway for trying to get between Chrom and Sully. As her only surviving family, I have an obligation to teach her right from wrong. With my girlcock.

That settles it.

While I was busy grappling with the moral quandaries inherent in magical-penis-girl-rape, Aversa had been thrashing against her bonds, but Tharja's preparations were flawless. As I rounded the foot of her table, erect penis swinging free, she had calmed down, but was already hot and sweaty from exertion.

I began by rubbing my cock against her groin. Even through her clothes I could feel her quaking in anticipation. “You've been a very naughty girl, big sister” I began, placing my hands on her inner thighs. “I have to punish you now. I'm going to start nice and slow, but I will not end slow. Let's see if you can keep up.” Countless perverted fantasies I could be living out right now, and I settle on lesbian sibling incest, the most cliche of them all. Oh well, it works for Miriel and Ricken. There is just something about that boy in a skirt...

After this short grinding session I could feel a wetness between her legs. The ashamed, lustful look on her face left no doubt she was ready to move on from foreplay.

“Tsk, tsk, so eager Aversa. Patience is a virtue you must learn. Good things come to those that wait.” I stooped forwards and began tracing her right areola. Her nipples were poking through her shirt. “Let's start with your clothing, dear sister. Your attire sets the pace. Heavy armor like Sully's takes time to remove and tells a man you expect patience and commitment. When a man perseveres, you owe it to the both of you to enjoy it properly.”

I paused my lesson to adjust my position. Straddling Aversa, I scooted up her chest, toy soldier bouncing all the while, and started vigorously playing with her breasts. You better be paying attention to this Tharja. “And then you have girls like Olivia and her whore-curtain. Her clothes practically fall off. No effort needed. She practically screams 'I'll fuck even you because I'm a desperate tramp'. And a night in her bed is like Sully's cooking: everyone has had it and no one enjoys it. When you're with a girl like Olivia, you just want to finish up and forget about it. It ends too quickly for anyone to really enjoy it.”

Another pause as I inched forward to slide my girth between her massive melons. I thrust a few times in silence before continuing my lecture. “Of course, Sully and Olivia are at the far ends of the spectrum. Not every girl wants to wait for Mr. Right like Sully. But where does this leave you, big sister?”

I paused the titfuck to moisten two fingers with my saliva and jammed them into her sopping vagina. This brought on a brief round of thrashing. In truth, my hardware needed the reprieve. Talking helped keep me calm, but even so I was steadily leaking seed onto Aversa's sweaty flesh-mountains. Fingering practice would have to do until I was ready to finish, because it simply wouldn't do to come early.

“The root of your problem, Aversa, is that you are being dishonest with yourself. Your body promises the finest of carnal pleasures, and your dress promises them immediately. Relationships, I am afraid, do not work that way. Good things take time to build, and you expect them instantly. You will never be satisfied with such expectations. Quality relationships take time to build. You need to learn to pace yourself. Consider tonight an example.” I withdrew my fingers from her pink depths and got off of her. Walking back to the foot of the table I began removing her smallclothes, slowly and carefully. “We have had our fun taking things nice and slow, haven't we sister? But the time is upon us -” Her underwear off, I positioned my questing wurm just before her gushing mound “-to go fast”

At last, I thrust into her with all my might. Aversa's hungry cunt tightened like a vise as I penetrated her, the length of my shaft sliding in and out as quickly as I could thrust my hips. Moving as one we shook the table, my “sister's” mammaries glistening with sweat and sperm as they fought to escape the scrap of cloth barely covering them. Aversa's eyes rolled back, her face forming a picture of pure ecstasy even around the gag. With one primal grunt I came, a bucketful of sperm flowing into her. The witch's greedy hole swallowed every last drop.

Exhausted, I reluctantly unsheathed my member from my sister. She continued to twitch in pleasure as I turned to Tharja, who I swear hadn't moved a muscle during the entire session. And she was blushing. Have I finally found something Tharja enjoys as much as holding hands?

“You said the potion was temporary, right Tharja?”

“Yes. It is supposed to last a week.”

This could be a problem. At least I don't dress like Olivia. That left one last question, though.

“Tharja, I can't get a girl pregnant with this thing, can I?”

Tharja started blushing harder than I had ever seen her. She walked up to me, our faces almost touching before she whispered, “You just made Morgan. Lets make Noire.”
