She pushes you on your back.

Elena stares at your naked body, tracing a hand, gently, across your large tits, down your stomach and teasingly touched your pussy. "Getting wet, are we?" she teased, sliding her hand back up to your tits "Want that?"

You just stare at the ceiling, not caring. You planned it so carefully. You were going to take a blindfold, ball gag, and a pair of cuffs and take her by surprise. Instead, you are naked, your sister finally getting her wish, and...her hand feels too good. You squirmed as both of her hands roughly groped your tits, digging her nails in, and leaving scratch marks. Every so often, she uses one hand to rub your pussy, near it, and then stopped. She grabbed the cuffs and bound your hands. "Ignoring this? You'll be begging for me to make you cum, very soon."

You squirmed slightly and tried speaking thru the gag. She used her tongue to tease your clit, sucking on it, licking it. You tried to close your legs, but she **** them to stay apart. She didn't comment, only gave a devilish grin, then continued her **** on your pussy with her tongue. She crawled up to your face and kissed your gagged mouth, licking your lips "You wanted to dominate me?"

You nodded. She laughed a little, then kissed your neck, trailing kisses down to your nipples and sucked on them, before returning to face you "You know I'm not the best sub. Want to see why?"

You shook your head, but she either ignored it or took it as a yes. Either way she lowered her head "Want to see why my girlfriends never stay longer than a week?" you shook your head again "Too bad." she teased your pussy "Want my fingers in your wet, slutty, pussy?"

She was kind enough to let you consider how good or bad you wanted to be.
