Meet Erica's sister

In the evening, Erica prepared for her sister's visit. Her sister, slightly taller and slimmer than Erica, arrived punctually. She had the same long blonde hair and blue eyes, but her figure was less athletic and more delicate. She wore a loose, summery dress that accentuated her slender figure and long legs.

As she entered and after she greeted Erica, she turned to me with a shy smile. "Do I need to do anything special to come in?" she asked, her voice tentative, betraying her uncertainty about the latest rules. She was aware of the unique relationship dynamics in our household and seemed eager to show her respect for them.

I smiled reassuringly. "No, the entrance blowjob rule only applies to my three girls. You're a guest, so you don't need to worry about that."

She nodded, looking relieved but still curious. "I understand. But if you want, I can still contribute in some way. Maybe by letting you have access to my body?" she offered, her voice softening with a mix of shyness and willingness. "I want to show my appreciation for how you take care of my sister."

Her offer was unexpected but appreciated. "Thank you," I replied, my voice warm with gratitude. "I would love that." Erica smiled, clearly pleased with her sister's willingness to join in our unique dynamic.

As we moved to the living room, the anticipation was palpable. I began to explore her body as she and Erica chatted. Standing behind her, I let my hands roam over her slim form. Her dress felt soft under my fingers, clinging to her body in all the right places. I could feel the warmth of her skin through the fabric, and she shivered slightly under my touch.

Her delicate frame was a contrast to Erica's athletic build. My hands moved gently over her shoulders and down her arms, then back up to her neck. I could feel her pulse quicken as I traced the line of her collarbone. As my hands slid down her back, I felt her relax into my touch, her body becoming more receptive.

Erica's sister let out a soft sigh, her head tilting slightly to give me better access. I moved my hands to her waist, pulling her gently against me. She responded by pressing closer, her body melting into mine. I could feel her breath hitch as my hands moved lower, tracing the curve of her hips.

Erica watched us with a smile, clearly pleased with her sister's willingness to join in our unique dynamic. The atmosphere in the room was charged with a new kind of anticipation, a blend of familiarity and fresh excitement.

The soft fabric of her dress shifted under my hands, revealing glimpses of her smooth skin. I took my time, savoring the sensation of exploring a new body while maintaining a respectful distance. Her offer was a gift, and I intended to appreciate it fully.

"John is always so attentive," Erica said with a grin. "He knows exactly how to make a girl feel special."

Her sister nodded, biting her lip as my hands roamed over her thighs and up to her hips. "I can see that," she murmured, her voice trembling slightly.

I continued my exploration, sliding my hands under her dress and feeling the warmth of her skin. She shivered under my touch, her body responding eagerly. As I caressed her, Erica and her sister continued their conversation, their voices a soothing backdrop to the intimate moment.

My hands moved to her breasts, smaller and softer than Erica's. I massaged them gently through the dress, feeling her nipples harden. She closed her eyes and let out a soft moan as I deepened my touch.

"Are you okay with this?" I whispered into her ear, my lips brushing against her skin.

She nodded, her breath hitching. "Yes, it's... it's nice."

Encouraged by her response, I continued my exploration. I moved my hands down to her waist, tracing the curve of her hips. Her skin was smooth and soft, and I felt her react to every caress. I squeezed her hips lightly and let my fingers glide over her firm, round buttocks.

I lifted the hem of her dress, exposing her long, slender legs and the delicate lace of her panties. Her skin was flawless, a soft, creamy white that contrasted beautifully with the light fabric of her underwear. I ran my hands up her thighs, feeling the muscles tense slightly under my touch.

As the sisters continued their conversation about their week and other sisterly topics, the contrast between the normality of their chat and the intimacy of my actions was striking. It highlighted the unique dynamic we shared.

"Let’s move to the couch," Erica suggested, leading her sister.

They sat down, and I followed, taking my place behind Erica's sister. She settled next to Erica, and I positioned myself so I could continue my exploration. I lifted her dress higher, exposing more of her legs and her panties.

"Your dress is lovely, but I think it would be even better on the floor," I said playfully, starting to pull it over her head.

She giggled nervously but raised her arms to help me remove the dress. I gently pulled it off, leaving her in a matching set of delicate lace lingerie. The bra and panties were a pale blue, almost white, which complemented her fair skin and light blonde hair.

I knelt beside her, letting my hands explore her body more freely. I cupped her breasts through the thin lace of her bra, feeling her nipples harden against my palms. She leaned back, her body relaxing into my touch.

Erica continued talking, occasionally glancing over at us with a smile. "He really knows how to make you feel good, doesn't he?" she teased her sister.

Her sister blushed but nodded. "Yes, he does."

I unhooked her bra and slid it off, revealing her small, firm breasts. Her nipples were a soft pink, standing out against her pale skin. I took one nipple into my mouth, sucking gently and flicking it with my tongue. She moaned softly, her hands gripping the couch cushions.

Moving lower, I hooked my fingers into the waistband of her panties and slowly pulled them down, exposing her smooth, pale skin. She had a small patch of light blonde hair above her pussy, neatly trimmed and soft to the touch. I ran my fingers through it, enjoying the sensation.

"You're beautiful," I murmured, my lips brushing against her skin.

She shivered, her body responding to my touch. "Thank you," she whispered, her voice barely audible.

I continued to explore her body, my hands moving over her hips and thighs, caressing and squeezing gently. She opened her legs slightly, giving me better access. I leaned in, inhaling the sweet, musky scent of her arousal.

I then licked her inner thighs, and she let out a series of soft moans, her body trembling with anticipation. I moved my mouth to her pussy, parting her lips with my tongue and tasting her deeply. She gasped, her hips lifting slightly to meet my mouth.

"God, that feels amazing," she breathed, her hands tangling in my hair.

Erica watched us, a satisfied smile on her face. "Just relax and enjoy it," she said softly to her sister.

I took my time, savoring the taste and feel of her. I explored every inch of her pussy with my tongue, teasing her clit and dipping into her entrance. Her moans grew louder, her body writhing under my touch.

When I finally pulled back, she was breathing heavily, her skin flushed and glistening with sweat. I kissed my way back up her body, savoring the feel of her soft skin against my lips.

"Thank you," she whispered, her eyes half-closed with pleasure.

"You're welcome," I replied, kissing her softly on the lips.

She looked over at Erica and then back at me. "Do you mind if we start dinner now?"

"Of course not," I said, giving her a final gentle squeeze on the thigh. "Go ahead."

The sisters stood up and headed to the kitchen to prepare dinner together. As they worked, Erica glanced back at me with a grin. "You know," she said playfully, "if you keep this up, she might never want to leave."

I chuckled, watching them move around the kitchen. "I wouldn't mind that at all."

As they cooked, the smell of delicious food filled the air, and I settled back on the couch.
