“Strictly speaking, your G-spot is somewhere else, inside your pussy, and very hard for most guys to spot. Men’s G-spot consists entirely of their prostate, sis. Though there’s also your clit, of course. I’m surprised that you haven’t cum from that yet. Anyway, a deal’s a deal. Bend over again, sis. Nice kiss, by the way. Kinda steamy there. If I didn’t know better, I’d think that you like me in very … unnatural ways. Very … Targaryen ways,” I teased Becca as I slapped her buns repeatedly in her bent position.
Becca didn’t say much … she was too busy cumming … and very loudly. It was a bit of a mess, actually, but a truly hot mess, with her lady juices leaking down her thighs from me licking and spanking her firm booty. We had definitely crossed the line into some very Cersei-Jaime territory, as it happened, and I was pretty sure that Becca had me busted, too. There was no way that I could really, honestly claim that I wasn’t attracted to my own sister that way. I quite obviously was, but it was mutual, so what to do about it?
“Yeah, like you didn’t love it … every bit as much, bro! Please, sir, can I have another!” Becca now begged me to spank her some more.
It made me wonder … how far was too far. We wouldn’t … go all the way, not with her having a boyfriend and such, and us being kin, right? Damn, though … I would really have to rub one out to Becca soon if this kept up! Even so, I continued spanking my elder sister while she kept asking me for more swats. She really came repeatedly now … my hands stinging her bottom and leaving her ass red, but she seemed to love every last minute of the spanking.
“Oh … fuck … oh, that’s righteous! Yes … thank you, baby brother! You’ve now made me cum literally a dozen times! That’s by far the most ever in my lifetime! From now on, bro … you can spank me whenever you like … and you can lick my ass, too! Here’s my panties, Simon. For keeps. They’re yours now. I promise … my bottom is yours to spank … forever. To lick, too, if you can make me cream myself like that!” Becca kissed me again, very roughly, even biting my lower lip just enough not to draw blood.
“Yummy … my butt really is tasty, isn’t it? No wonder you went after it like Pooh with a honey jar!” Becca smirked as she spotted my chubby, “best rub that one out, bro, since Heather’s not around to drain it!”
Well, I couldn’t very well pressure my own sister to suck or ride my cock, could I, though maybe I could win a handjob in another bet or dare. There was always that. I thought that was the end of it, at least for now, of course. I went to take a shower and indeed stroked myself to orgasm, cumming very hard all over the shower floor. I was glad that the hot water cleaned it up, of course, but then I had to piss a nice, hot stream as well.
Nasty images of making Becca drink my hot piss or swallow my jizz naturally came to mind to me, but I knew that was in vain for the moment. We had pushed the envelope enough for both of our comfort zones, I could just tell. Even I would be awkward asking for more from Becca at this point. As it was, she still had to get Eddie to sign off on that hall pass. There was no guarantee how he would take the news, given that the only guy readily available to punch her ticket was me, her own brother.
I slipped out of the shower at last, dried off, and reached for my boxers, but they were gone. There was a note where they should be instead, and yes, it was from Becca.
“Hey, Bro, if you’re wondering your undies are, well, it’s a fair trade. Remember, I gave you my panties, so I’m taking your boxers. Nice, musky smell to them, by the way. Perhaps I’ll wear them and add my own scent to them, what do ya think? Love, Sis. P. S. I’m capitalizing the letter b from now on in ‘Bro,’ because you definitely earned it today. Maybe we should do more fun and games of this kind, once Eddie has granted me that hall pass. XOXO.”
All in all, not the worst way to spend my quarantine in central Pennsylvania, right?

“So, that was a pretty neat little bet, wasn’t it, bro? Even better than yesterday, when we bet over kissing with tongue and seeing each other naked? And then the day before, when we bet over kissing without tongue and just seeing each other bottomless? Or the day before that, when we dared each other to streak. Or the day before that, when we dared each other to moon people,” Becca reminded me now.
I squirmed as she planted her bare ass on my lap for some reason while we watched Game of Thrones per her request.
“Or the day before that, the dare to shower together? That was … literally steamy!” I replied, making Becca smirk a bit.
“Or last night, when I cooked for you, wearing nothing but my apron, just like Jane March on Color of Night? Or when I modeled for you those times in the nude or in my undies or just in Goth outfits or that one time in nothing but my boots? Nice boots, weren’t they?” Becca continued, knowing that I was sure to grow very stiff with her teasing.
“Those weren’t technically dares. They were just … weird random stuff that you did to cock-tease me, I think. I don’t know why, but you love to tease me that way with your delicious flesh!” I responded.
“Oh, like you didn’t love every last second of it? Or when I brought my friend Janine over and we streaked together through the house? Or the time that she and I both burst in on you in the shower. Or when you ‘accidentally’ caught us in just our bath towels. Little hint, bro, it wasn’t an accident. I just love to tease you for being a naughty perv who likes to see your big sister naked,” Becca laughed very hard then.
