This will make more sense if you read the earlier parts. Don't worry, they're fun, action packed, and build the tension. Read them first! Also, all characters in sexual situations are 18 years or older. Enjoy.
A shiver ran down Julie's spine. It was cold in the hall as she stole out of her bedroom wearing nothing but an oversized t-shirt and panties. She put her hand protectively on her stomach. She could just feel the growing bump there. She wasn't going to be able to hide it forever.
Softly, Julie closed her bedroom door. She didn't want to wake her oblivious husband sleeping in their marital bed. Also, Brad and Penelope slept right across the hall. She didn't want to wake them. But more than anything, she didn't want to wake the house. She remembered well the night Frederick Palmer had chased her down the hall. She hadn't seen him since. Maybe he'd wandered off never to return. Julie padded down the hall and stopped in front of Daniel's door.
Julie reached for Daniel's door, but then stopped. Not tonight. Julie tried to give her twins equal time. She took a deep breath and thought of the pleasures that awaited her in Brittney's tower room. She hustled down the dark hall and up the stairs.
Outside Brittney's door, Julie paused. All three of her children slept under her roof that night. Brad had always been different than the twins. He rebelled at his outsider status. But now, he was more the odd one out than ever. Julie had bonded with the twins like she'd never imagined possible. Poor Brad had no idea how he'd been pushed farther to the margins. Even his own wife had betrayed him for Daniel and his monstrous penis.
Somewhere in the house, a clock ticked with ponderous precision. Julie opened her daughter's door and slipped into her room.
~~
The clock struck eleven, and then twelve, and then one. Penelope lay in bed, her body a taut mess of anticipation. Even as Brad snored next to her, she couldn't sleep a wink. She just lay there, waiting and daydreaming about the things she'd do with Daniel. Penelope let the clock tick for a while after it struck one, and then she eased out of bed, careful not to disturb her husband. She had her t-shirt and panties on, but it was cold. She pulled on some sweatpants, grabbed two blankets Julie had left for them, and moved out into the hall. All was quiet as she moved toward Daniel's room. She clutched the folded blankets tightly to her chest.
Once in Daniel's room, she moved next to his bed and shook him awake. "Danny? Wake up. It's me."
"Mom?" Daniel rolled over onto his back. His dick was so hard it was almost painful. "Get under the covers, Mom."
"It's me, Pen." Penelope paused and cocked her head. "And that's a weird thing to say."
"What?" Daniel opened his eyes and looked up at his beautiful, blonde sister-in-law. "Oh, hey, Pen. Sorry, I was confused."
"Right." Penelope smiled down at him. "I wanna go to the tower room with you. It's going to be gorgeous with the moon and snow. The perfect place to screw." She held the blankets up for him to see. "And I brought blankets in case we get cold."
"We can't ... screw in my sister's room."
"The other tower, silly." She pulled the blanket off her eighteen-year-old brother-in-law and saw he had on flannel pajamas. There was a large bulge that told Penelope he was very ready for her. "Come on, we only have a few hours."
"Okay, okay." Daniel rose. "I can carry the blankets." He held out his arms.
"Always the gentleman, Danny. Your brother could learn a thing or two from you." She handed him the blankets with a wink and led him back out into the hall. They marched across the house and ascended the stairs to the west tower.

"I love the way these feel, Mom." Brittney groped her mom's heavy boobs through the thin cotton of her t-shirt. "They're so full." She lifted herself onto her toes, leaned her head up, and planted a kiss on Julie's lips.
"Oh ... mmmmm ... sweetie ... that feels ... good," Julie said between heated kisses. She felt her daughter press into her, and Julie backed up until her panty-clad butt touched one of the cold, gently-curved windows that surrounded the room.
"Shirt ... off ... Mom." Brittney lifted the shirt over her mother's head and tossed it behind them. When her mom had come in, Brittney had been reading in bed. Her bedside lamp was still on, and she admired the perfect, hanging mammaries in the warm glow. Those little blue veins that crisscrossed Julie's boobs were to die for. "Midnight snack?" She lowered her mouth to Julie's right nipple and was rewarded with that sweet, warm elixir.
"Of course, pumpkin. Ooohhhhhhhh." Julie cupped her daughter's brown hair and pressed Brittney's face into her boob. "You're so close to my ... heart ... when you're back at my breast."
Brittney suckled for several minutes, and then pulled off the nipple and looked up at Julie with a mischievous grin. Milk dribbled down her chin. "Have you tried it yet?"
"What? My milk? No, of course not. That would be --"
"I bet you could get your nipple in your mouth. I mean your boobs are really big, Mom." Brittney traced her fingertip along the bottom of Julie's left tit and watched as her mother shivered.
"Well, maybe." Julie shook her head. She wanted to say no, but she knew there was very little she wouldn't do for her twins. "Like this?" Julie lifted up her right breast from underneath, angled the nipple up, and placed it in her mouth. "Mmmpppphhhhhh." The milk was lovely. She could see why Brittney fed on her so often. The warm, rich liquid filled Julie's mouth and ran down her throat. She closed her eyes, and felt Brittney go back to sucking on her left nipple. They both gulped greedily, standing in Brittney's chilly room.

"Look, Danny," Penelope whispered and moved through the shadows to one of the east facing windows in the tower room. "Your sister's light is on. And she's with ... she's ... oh, my, God." Penelope stood dumfounded near the window.
"We should just go back to ..." Daniel walked up next to Penelope and froze when he saw what she was looking at. The blankets tumbled from his hands. "Are they ... are they both sucking my mom's boobs?"
"Yeah." Penelope looked over at Daniel in the moonlight that fell through the windows. Along with the surprise she expected to see in his face, she also caught a hint of something else. Jealousy maybe? Longing? She looked back to the other tower. "Can they ... see us?"
"I don't think so. With a light on inside, they can't see anything outside." Daniel scanned quickly around the house. Snow fell lightly and covered the nearby fields and trees. It was pretty. Penelope had been right about that. He looked back to his sister's room, where Julie held one of her tits up to her mouth, and Brittney had her mouth clamped on the other one.
"This is ... surprisingly ... hot." Penelope quickly pulled off her sweatpants, shirt, and panties and put her hands on the window frame. She stuck her butt back at Daniel. "You need to put it in now, Danny."
"Yeah, okay." Daniel pulled off his pajamas and microboxers. He glanced down at Penelope's pale, round butt. "But if they turn off the light, we need to drop to the floor."
"Okay." Penelope spread her legs to the sides, lowering her hips. "Put it in, put it in, put it ... aaaaaahhhhhhhhhh ... God, you're so deep." She felt that long shaft slip in from behind, her eyes still fixed on the mother/daughter feeding in the other tower. "If we ... ugh ... ugh ... caught them like this ... they must have been doing ... this for a while. It would be lucky if we caught them the one time they ... um ... go at it." Penelope could see the pleasure on Julie's face as her mouth pursed around her own nipple. It looked like she was actually gulping something down. "Jesus, Danny. I think she's got ... milk ... in those oooohhhhhhhhhh." Penelope thrust back at the eighteen-year-old teenager, while his twin kissed her way down Julie's belly and lowered herself down so that she was mostly out of view. Penelope could just see the top of Brittney's brown head between Julie's legs.
