“Sarah, if you’re ready, it’s time for you to lose your virginity to your brother and become a woman and his lover.”

“I’m ready, Mom,” she said with a smile.

Ellie moved to lie beside Sarah as Donny came up between her legs. He was pleasantly surprised when his mom leaned forward and sucked on his cock to make it fully hard.

Sarah had to hide her enthusiasm for her brother and pretend to their mom that this would be their first time. Poised above her slender body, he lowered himself to rest lightly on her. They watched as his hard cock poked and prodded at her pussy. Ellie told her to gently grasp it, then guide the head into her.

“See, instinct is telling you you want to mate with Donny by guiding his cock into your pussy.”

“After our first time, will Donny and I be allowed to continue fucking?”

“Yes, as often as you want,” Ellie agreed. “I’m not sure what your father will think of his son and daughter being young lovers. I’ll warn you right now, and your dad would say the same, Donny, don’t you ever get your sister pregnant.”

She placed her hands on his arms, her eyes twinkling with love and lust for her brother as she felt his cock enter her. He lowered his body, his chest pressing against her firm breasts.

“Mom has to think this is our first time,” she whispered, and he nodded in agreement.

“Can you feel his cock entering you?” Ellie asked.

“A little around the edges of my hole.”

“Push in deeper, Donny. Sarah, you might feel a little discomfort as his cock goes past your hymen, your virgin cover.” Ellie placed her hand on his ass, urging his cock deeper into her daughter.

“Do you feel any pain?” She wondered. “You might bleed a little from his cock penetrating you for the first time.”

“None at all,” she said, smiling at her lover.

“Donny, you might become overly excited about having sex with your sister. The mark of a good lover is being able to stall off cumming. When you feel the urge to cum, stop and let it subside. You should be able to do this twice, then finally cum.”

“I’ll try, Mom, but I must admit having sex with Sarah is very exciting. I never thought this would ever happen, and with your approval.”

“And it should be exciting. Sex is healthy for you and makes you feel closer to each other.”


Donny established a steady pace, fucking Sarah. Ellie had to look closer, watching her son’s cock repeatedly enter her daughter. When she could, she’d feel Sarah’s breast or suck on her nipple.

Ellie laughed lightly, noticing Buck sitting with his long, rubbery cock protruding from excitement. “Okay, you sat patiently enough.” She bent her right leg at the knee, opening her posture to him. He came to her, wagging his tail, and began licking her pussy.

“Now this is how to have fun: watching my son and daughter fuck while our dog licks my pussy,” Ellie smiled.

Sarah’s longing for her brother was stronger than she could have imagined, especially with their mother watching.

“How are you doing?” She asked several moments later.

“I’m doing really good. I never expected my first time to feel so wonderful, especially doing it with my brother.”

“That’s good to hear. A girl’s first time should feel very special.” Ellie placed a hand on Sarah’s ankle. “Put your heels on his hips; the change in angle of your pelvis will allow his cock to go into you deeper.”

She did as instructed. “I can feel my cock thrusting deeper, that’s for sure!” Donny grinned.

“What does her pussy feel like to you?”

“It feels so soft, warm, and snug around my cock. I’ve had to slow down once already, or I would cum too soon.”

“Just imagine, Donny, Mom will let us fuck and have all the sex we want!” Her eyes gleamed with love and lust for him.

“Mom, you know how I hate thunderstorms. Donny would let me lay on top of his bed with my own blanket so I wouldn’t feel so afraid. Now we’ll be able to fuck while it’s storming out.”

“Yes, you can. I hate the storms too, and your father’s excellent fucking would make me forget about the wind, rain, lightning, and thunder.”

“What will you do if we have a storm while Daddy is away?” Sarah asked.

“I imagine that I’ll let Donny help me the same way your dad does with a good fucking. In fact, while your father is away, there is no need for you to sleep in your own beds; we can all sleep together.”

“And both have Donny fuck us!” Sarah enthusiastically agreed.

“Come on, lightning and thunder!” He cried out, and they laughed.
