Yes.

She looks back at you, looking more embarrassed than angry, although... She does look like she might have liked it.

You smirk to yourself and spank her again. She was expecting it this time but the soft moan coming from her mouth suprised even her. It seems big sister might just be a little masochistic. _Hopefully a little more than a little. _ you think to yourself. Which frankly, suprised you. You smirk as you bring her other hand to her unspanked ass cheek, slapping it a little harder than the other side, which made her moan even louder.

"Mmm. Like that Kiera? I didn't know you liked being spanked. " you say to her in a teaseing tone of voice as you thrust in and out of her, placing your hand and rubbing the smacked ass before spanking it again.

"E-Even I didn't know. " she says though a couple of moans, her face as red as her ass. She did find it a little embarrassing, but tons of people like it so it's nothing to be ashamed of. She lays there, being spanked and fucked by her little sister and loving it. Needless to say, it didn't take her to long to cum, and again, and again. Until finally the vibrator is removed from her pussy with a slight whine from her.
