When he’d recovered, she reached back with one hand to stroke his balls gently. “Feel good bro’?”
“That felt frickin’ awesome,” Bobbie said groggily.
“Good, I’m glad. But…” she poked him in the chest, shaking her head with a crooked grin. “You came too soon. Way too soon. When you knew you were coming you should have stopped and gotten yourself under control. Girls always come first, buster. It’s a good thing I’m your sister. Any other girl would be pissed right about now.”
Bobbie was apologetic, “I know, sorry, it was just too good.”
“I’ll take that as a compliment,” she smiled down at him and tucked a lock of her gold hair behind her ear. “What I want to know, studly brother, is if you think you can you stay hard still. This is round four for you now right?
“I can try…”
“Let me rephrase, brother dear,” she leaned down and lapped nastily at the tip of his nose, punctuating each phrase that came next. “Your sister is telling you to that keep that nice… big… cock… hard… in her hot… wet… tight… little… pussy.”
“Whoa,” Bobbie snickered, “The slutty talk is totally helping,”
Heather giggled. “I kinda figured it might. But I know how to seal the deal…”
Heather’s hands went to the bottom of her pink babydoll t-shirt. She slowly pulled it up, bunching it in her hands to expose the flat, tanned surface of her belly. She tugged it up further and the bottom of her pink bra peeked out.
She eyed her brother shrewdly, “I bet it would help if I took off my shirt. Wouldn’t seeing me shirtless help you stay hard for me?”
Bobbie could only nod.
“Touch my stomach Bobbie,” she reminded him. “Girls want to feel your hands on them while they make love. It’s not just about the poking part.”
Bobbie stroked her belly with his fingertips and she pulled the shirt up over her head and threw it to the floor. She was now naked except for her bra. Heather’s giant round breasts were pressed together in its over-filled pink cups. The fabric was sheer enough that the outlines of her slightly darker pink areolas were visible and her erect nipples made distinct bumps. She cupped her breasts through the bra and squeezed them until they threatened to pop out.
“So, does seeing your big sister’s tits help?” she asked with wide-eyed mock innocence.
It was a completely rhetorical question.
“They’re the ones you’ve fantasized about, Bobbie. The ones you used to picture when you jerked off in the bathroom.” Heather grinned knowingly.
The surprise showed on Bobbie’s face. “Huh? How did you…?
“Oh come on, I knew. You masturbated twice a day for the last three years before I left for college, you dope,” she laughed. “Wanna know a secret? Sometimes I snuck up to the bathroom door and listened, wondering if I’d hear you call out my name. It’s a good thing you never did. I might have kicked down the door and finished you off myself.” Heather nibbled her lip. “Did I make you horny back then, Bobbie? Was it hard to look at me and not touch me?
“Yeah,” he admitted sheepishly.
Sam’s chimed in from next to me, “You’re getting pretty good at the naughty talk there, girlie.”
