Bobbie was switching from one breast to the other, lost in the dream of his sister’s huge, perfect tits.
She screwed herself down onto him tirelessly. It had taken Bobbie three orgasms, but he could now hold out against the sucking heat of his sister’s vice-like teen sex.
Heather’s motions were soon getting more erratic, her face more flushed. She turned her head towards us and her eyes opened.
She was so lost in that faraway pleasure place that I could tell it took a moment for her vision to focus and actually see us. I had wondered if she had forgotten we were even there. Her blue eyes flashed and she smiled a wide, wanton grin as she continued grinding down onto her brother. With his face buried in her succulent young breasts, Bobbie was just along for the ride.
Heather shivered and started slamming roughly down on him. She licked her lips where they’d gone dry from panting and she moaned. Her pistoning became more urgent. Her hips were a blur as she skewered herself on her brother’s long shaft.
“So damn good, ” she mewled.
“Go ahead, sis, I’m…”
But she didn’t need his permission.
“Shhh!” she hushed him abruptly. “Keep licking my boobs. God, I love having your mouth there. I used to have this fantasy about you sneaking into my room in the middle of the night: I would fake being asleep while you slipped under the covers to lick and suck my nipples through my t-shirt. In my fantasy, I’d come so damn hard just from that – not even touching myself. Then you’d just sneak back out of my room and we’d pretend like nothing happened. Damn that was so fucking hot.”
Heather looked down at her brother, her eyes were glazed as she rode him. She was half here and half in her old fantasy. All pretenses of teaching him anything right now were gone. She was using him now.
“You’regonnamakemecome,” Heather blurted it out so fast it came as one long word. “You’regonnamakemefuckin’come!” She was gasping for air now. “Coming on my brother’s cock. The first pussy to come on my brother’s long hard virgin…”
Heather couldn’t even finish her own sentence – her orgasm stole her breath. She cried out as it raced through her. Still, she kept skewering herself on her brother. She shook her head. Her muscular thighs rippled and twitched. Her toes curled. Her hands clutched the bedspread. But she kept riding him up and down. Kept using. Kept fucking him. It was breathtaking.
“Whoa, that was really good,” she said hoarsely, still bouncing slowly. “Follow me Bobbie, I want you on top now.”
They rolled together, never separating, until Heather was on her back and Bobbie was above her. They started fucking steadily again. Bobbie eyes were locked on the rocking of his sister’s large round tits as they humped together. She wrapped her legs around him and rose her hips to met him eagerly.
“Sis, I… I love you,” he said softly, looking down at her.
“I love you too, Bobbie.”
“Maybe we should have done this earlier, sis.”
Heather smiled. “Uh uh, that would have been illegal, silly. We had to wait until you were a grown up.”
