Listens in on her way to the bathroom

Lil carefully moved Eric's arm off from her and got off the bed, making her way to the bathroom in the nude.

As she went past Gary's room, Lil could hear Bernie moan and the sound of the bed springs creak. She paused to listen.

"Oh yeah Gary, oh fuck," Bernie said. "Oh yes. Real slow. Ahh...unggggh. Oh yeah."

"Oh God you're so hot Bernie," Gary said. "Uhh."

"Oh yeah move your cock now. Oh fuck. Oh yeah," Bernie said.

"So. Fucking Hot," Gary said. "God you feel so good."

Gary's bedsprings creaked rhythmically, speeding up bit by bit.

"Yeah, faster," Bernie said. "Deeper. Oh."

The air was warm, but Lil felt cool as the sweat from her fuck with Eric slowly cooled on her damp skin and hair. Was Gary going to come with Bernie like she had come with Eric? Eric. So sweet. So nice. So good with his arms around her. So good inside her pussy.

"Oh yeah. Oh yeah," Gary panted. Skin slapped against skin. Bedsprings creaked. "Uh-huh. Ohhh."

Lil listened hard. Gary sounded close. She knew that last note in his voice from when he jacked off. She liked hearing Gary come. She held her breath.

Bernie moaned. There was a low electric purr. Bernie's voice deepened and she moaned louder. "Uhhhh, ohhhh, mmmhhhh. Yeahhhh."

Lil's mouth twitched up in a grin. She knew Bernie liked her vibrator, but using it while she fucked? Yeah. Fuck yeah!

"Bernie I'm gonna come!" Lil's brother cried.

"Yeah, gonna come too. Come with me lover. Come in my ass," Bernie crooned as her vibrator purred away.

Lil's eyes widened. Gary's penis was pretty big, she knew from the sauna and the nudist resorts their family frequented. Bernie was taking Gary's big boy in her ass?

"Yeah, yeah," Gary whimpered. "Oh Bernie. Gonna."

"Gary love. Honey." Bernie's voice was low, almost a moan, a groan. The vibrator hummed along. The springs creaked.

"B-bernie?" Gary whimpered.

"Nn-hh-uh," Bernie panted as her vibrator buzzed. "Oh shit oh no oh fuck ooooh Gary COME!" she commanded.

"C-cc-uhhh. Ahhhh!" Gary groaned.

Gary and Bernie's voices rose together, drowning the growl of Bernie's vibrator.

Lil smiled to herself and walked into the bathroom. After Lil got up from the toilet, Bernie walked in bare naked, the glow of sex and satisfaction emanating from her.

Lil studied Bernie carefully. Lil had seen women in a happy haze after sex a few times -- well, and her mom every Sunday morning -- but Bernie was something else. The curvy, mop-haired brunette seemed to just radiate MY MAN FUCKED ME UP THE ASS TILL I CAME AND I LOVE LOVE LOVE IT from every curve of her body and every pore of her naked golden skin.

Bernie's hazy eyes suddenly focused on Lil and blinked in surprise.

"Oh hey Lil, didn't know you were in here." Bernie said, about to step back out of the bathroom.

"It's okay Bernie, come in, I always have to pee after I do it." Lil told her brother's girlfriend. She waved her hand. "Just go ahead."

Bernie laughed. "Me too," she said. "Thanks, Lil." Naomi Bernice Bernstein stepped in and closed the door, unashamed now that Lil had welcomed her.

Lil washed her hands and watched her brother's latest lover in the mirror as Bernie settled her nude golden body on the toilet.

A bubbly tinkling sound started as Bernie's urine streamed into the bowl. "So how was it?" Bernie asked with a mischievous grin on her face.

"It was incredible, I've never felt that way before. I've had sex plenty of times, but I've never made love before." Lil said with a beaming smile on her face.

"I'm so happy for you, I felt the same way with Gary the first time we made love." Bernie replied. She patted between her thickly sex-swollen labia with a fold of soft paper, then stood up and went to the sink. "Your brother was such a surprise to me. I never thought I would love a man. Maybe choose one to father my child. But Gary won me over. Gary is so much sweeter than he seems at first. So good to me. He makes me feel beautiful all over. More beautiful than I ever felt with a girlfriend."

"I think you're beautiful too," Lil said, looking at the naked, heavy-breasted young woman radiating heat and pleasure. "And Eric was good to me too. Really good. Thanks for introducing him to me Bernie." Lil said, giving Bernie a hug. Bernie's big warm breasts pressed against Lil and the gentle curve of her belly touched Lil's nude body. Bernie's full dark bush tickled Lil's sparse blonde one. Bernie's warmth felt so nice to Lil.

"Anything for my li'l sis." Bernie replied, giving Lil a kiss on the cheek.

"Anything?" Lil asked, sending a mischievous grin back at Bernie.

Bernie tilted her head. "Now just what are you thinking?" she asked, grinning back at Lil.
