“It’s about time, Big Brother.” Jenny winked at him. “I’d thought you’d forgotten about our deal and that I might have to go wake up Mom to tell her what I caught you doing earlier.”
It took several moments for Billy to get his brain engaged enough to respond. “Look, Jenny, I’m sorry about perving on your friends, I really am. But I don’t see what this…”
He again lost the function of speech as his sister casually lifted the negligee up and off, fully revealing herself to him. “What THIS is is me getting a little experience with the male anatomy before going off to college, and YOU, Big Brother, are going to help me.”
Billy was torn. It was one thing to be secretly fucking his own mother. But now, his sweet, innocent little sister suddenly wanted him too? Nothing good could possibly come from this, and yet he couldn’t deny the throbbing erection already forming in his pants.
Jenny noticed it too. “I knew it wouldn’t take much to convince you. Now bring that damn thing closer, I’ve been dreaming about getting a better look at it all day.”
As Billy approached the bed, Jenny sat up and moved to the edge of it. Billy stopped directly in front of her, and Jenny found herself now face to bulge with her brother’s erection.
Jenny suddenly felt… well, a mix of emotions, all at once, like clothes tumbling in the dryer.
She was excited, for sure, her pussy already swollen and wet. But she was also nervous. For all her bravado, she’d never done this before. She also felt quite intimidated by the size of the beast currently struggling to free itself from its cloth prison just inches from her flushed, freckled face.
Billy noticed her hesitation. “Hey, it’s okay. You don’t have to do this if you don’t want to, you know.”
“No, I want to.” Taking a deep breath Jenny found her resolve. Reaching out, she found the snap to his shorts, then the zipper. “You just might have to, um, coach me as we go. I mean, I’ve seen porn of course, but I always assumed most of what they do is… exaggerated.”
Billy laughed kindly. “Oh, for sure. Trust me, I’ve been with a few girls at college, and trust me, none of them ever came close to sucking or fucking like they do in porn. In fact only Mo…ummm, one ever managed to deep throat me all the way.”
Jenny tugged at her brother’s briefs, his cock jumping out like a coiled spring suddenly released. Her eyes went wide at her first good, up close look at it. “I can see why most girls would, um, struggle with that. I think I’ll start slow. Just, um….”
Her voice trailed off. She hated this sudden feeling of insecurity, of not knowing what she was doing. She wanted to be strong, take charge, show her brother SHE was in charge.
Taking his huge phallus in hand, she marveled at the heat of it, the pulse, throbbing in her palm. Billy was already groaning in pleasure and she’d barely even touched him. Jenny had a sudden revelation as the first drop of precum made an appearance from his swollen purple tip. She WAS in charge. Experienced or not, he was already putty in her hand.
