"Oh, I'm pretty decent, for sleeping, anyway," she decided. "But I have to check the house. Jenny and the boys are probably settled down in bed by now."
Light came from the boys room, though, and strange noises besides, so Cheryl pushed the nearly closed door quietly open. Ben and Neal were sitting on the sides of their beds, naked, facing each other across the center of the room. Shocked by merely seeing that her brothers were completely undressed, the blonde felt her nerves really curl up and buzz as she tried to find out just what the twins were up to.
At first she saw almost nothing. The viewing angle from the door was bad. Btu she heard sickly slapping noises and much panting and gasping from Ben and Neal. They sounded very hard at work. Their right shoulders were moving up and down fast. The blonde guessed they were pounding something with their right hands.
Barefoot, she padded around the foot of the closest bed, Neal's. Then, for the first time in her life, she saw a cock. Two cocks, in fact. Very stiff cocks. They boys' right hands were flashing up and down on them.
Cheryl hadn't seen Ben or Neal naked since their babyhood. Now she saw them not only stripped but playing with their dicks. The boys looked much alike. So did their pricks. Both hard shafts, sticking up long and thick, had fat purple knobs on their ends.
The twins did not yet see their beautiful sister. They were too much in trance pounding shivery thrills into their stiff cocks. With their eyes clamped shut in pleasure, they had jism-loads fizzing so high that all their attention was on their hotly rolling balls.
The young blonde couldn't believe the sight. A staring shock froze her, stopping her breath. Wanting to move on into the room and stop the mad cock-jerkings of her two very red-faced, panting brothers, she could not do it.
The virgin blonde didn't know about boys jacking off, so she was still trying to figure out exactly what she was seeing. All she knew was that Ben and Neal were totally naked and pumping hard on their solid pricks as they perched stiffly on the sides of their bed. But she felt sure they were doing something wrong, and when she could move again, she charged in on them to stop their gooey jack-jobs.
"Ben! Neal! Stop that!" she yelled on the run.
"Shit, Neal! It's Cheryl!" Ben gasped, but he ignored his sister and went on with his jerking, his load bubbling and burning too much in the base of his cock for him to interrupt his work.
"Aw, God, Sis!" Neal exclaimed, his primed excitement driving him on in his jacking too. "We can't stop now! We're cummin'!"
"What the hell does that mean?" Cheryl shrieked.
She soon found out.
She stood squarely between the beds. The twins sat on them facing her, both of them hammering their cocks to get their sizzling loads out. The young blonde had no idea how dangerous her place in the line of fire was. She was all eyes for Ben's stiff prod, hypnotized by it, watching its purple knob pop in and out of the milking tight circle of Ben's fingers, which were spattering juice around in almost invisible droplets.
The stiff prick stabbed up harder and longer through her brother's squeezing fist with every pump. It bucked. White gobbets of cream spurted out of the end of the long shaft, lightning-fast. Seeing this absolutely new thing startled Cheryl, and she gasped. Her stomach knotted and spasmed as the jetting white goop shot straight at her lovely face. The first blob of cum darted directly for her bugging left eye. She tensed to move herself and duck the globby missile, but couldn't. It cannonaded up too amazingly fast and true for that, splatting slappingly onto her wondering eyeball and over her eyelids as she froze in horrified shock again.
"Oh no! NO! Don't get me dirty! Don't slop that-!"
But another spouting stream of cum splashed hard on her chin. The spreading heat and slickness of the jism made her shudder. The next long shots of jism spewed between her lips, already sprung wide open by her cry of surprise. As the hot cream spattered across her pretty teeth and back over her curling tongue, Cherry's brains buzzed and she shivered harder.
The salty-sweet goo ran down her throat. She told herself she should spit her brother's buttery warm sperm out of her mouth. But she surprised herself by automatically swallowing the cum instead. In a helpless, hungering act of sexual depravity, she gulped the runny white jelly all the way down. Its syrupy lumps and strings slithered into her stomach and warmed her guts before she quite knew it was there. And Ben jacked more of the milky bullets at her.
"Uh, uh, UH!" he grunted, in time to his cock-jerking strokes. "It's shooting from way down in my balls! Sis! Oh, Sis! Oooooo! Look out! OH! AAAAAA GGG HHHHH!"
Cheryl realized she liked this new drink, in spite of her shock and shame. She had no idea how that could be. It just was. Guzzling sperm excited her in a strange new way.
