My cock is hard and pulsing, angry as my knot already swells.Fuck.It’s throbbing, aching, and so desperate for relief.Reaching down, I grip the swollen bulge, wringing it until I can get a modicum of relief.I squeeze the base of my knot in a pathetic attempt to ease the pressure that just keeps building.
"You're not gonna peek, are you?"she purrs from the other side of the curtain."I don't think I can go if I'm worried you're watching me."
"You're my sister," I grind out, running my hand up and down my stiff cock, stroking slowly, trying to stay quiet."I'm not going to fucking watch you pee.Besides, even if you weren't my sister, I'm not into that sort of thing."
"Step," she corrects as she lifts the toilet seat cover with a bang."So what are you into then?Is it safe to assume spanking?"
I bite back a groan as I continue to pleasure myself, keeping my breathing light and even so she doesn't know what I'm doing in here while she's just simply trying to relieve herself, my fist tight around my shaft as thick ropes of precum make the glide easier, slicker.
"I'm not having this conversation with you," I bite out."It's inappropriate."
"Oh," she giggles."And spanking me was?"
"It wasn't really a spank.Two light swats barely qualify."
I lean my head back as I jerk my hand up and down, faster now, my hips bucking slightly into my grip.My balls draw up tight, sending pinpricks of pleasurable pain down my spine.
"Did you like it?"she breathes.
I nearly come at that soft question.My cock jerks in my hand, so close to the edge.
"Did you?"I eventually counter once I can find the words.Several moments go by where all I can hear is the sound of the shower rushing near my ears."I don't hear you going.Are you done yet?"
"I'm trying.It's hard when I know you're in here."
"I suggested going somewhere else."
"I know."
Unable to help myself, I peek around the edge of the curtain.Lila sits there with her pajama shorts around her ankles, thighs spread, sitting on the toilet, so vulnerable and exposed.She bites down on her thumbnail as I continue to stare and jack off like the pervert I am.
From this angle, I can't really see anything, but my imagination doesn't need that visual.I already have more than enough from those godforsaken shorts she keeps walking around in.I can picture exactly what's between those thighs.It’s not hard to imagine how pink and wet she'd be.As she opens her mouth, I duck back behind the curtain, my hand working faster as I grip tighter.
"You never answered my question," she says."Besides, it's not like we're related or anything.If you tell me yours, I might tell you mine."
"Oh, you don't have to tell me," I blurt out as need swirls through my veins and pleasure coils tight at the base of my spine."I already know."
The only excuse I have for blabbing my mouth like this is that there's no blood in my brain.Not one drop.Every fucking bit is down in my cock and balls.
She doesn't answer but soon flushes the toilet and washes her hands.After, she stands in front of the curtain, and based on the shadow, she has her hands on her hips.
"What exactly do you think you know?"
"Forget it," I grit out.
Fuck.So close.Right on the fucking edge.
"Tell me," she demands, "or I'll rip open the curtain and embarrass you.Want me to see you naked?"
"No!"I roar.
"Then tell me."
"God, you're such a brat."
"Why don't you spank me again then?Not that it did all that much the first time."
Sparks blur my vision as annoyance, lust, and longing coalesce into one massive ball of need.Fuck, if she only knew.If she only knew I want to bend her over right now and spank her until she's sobbing, until her ass is crimson and she's begging.Biting down on my lower lip, I continue to furiously stroke, desperate to purge myself of this unholy desire.My fist flies up and down my shaft as my knot swells even more and becomes so sensitive that every splash of water that grazes it nearly makes my knees buckle.
