"But I'm your nominal sister-in-law! We can't do this!"
"Don't worry, if you don't tell, I won't tell and no one will know."
With that, I got up and sat next to Rachel. I spread my big hand to touch her white and tender thighs, reaching towards the hem of her skirt.
My fingers stopped at her panties, a warm sensation crawling up my body, feeling like an electric shock.
I gently stroked up and down the fabric of Rachel's panties, the crotch fabric was very small, so small that with a slight hook of my finger, I could touch her warm, soft labia.
I extended a middle finger and flicked it from bottom to top on her pussy, warm juices flowing out, wetting my finger.
Rachel sat beside me, her breathing gradually becoming low and rapid.
Her excited response was my motivation.
The speed and strength of my middle finger kneading on her pussy gradually increased.
The low moan Rachel had been suppressing in her throat slowly escaped.
"Feels good?" I looked at Rachel with an aggressive gaze.
A faint pink color appeared on her fair cheeks, her full red lips slightly parted, exhaling a sweet fragrance.
My desire grew even stronger, to the point where I could no longer suppress it.
I felt like I could go on with my sister-in-law for hours, and it would be even more perfect if she called me "husband." I could tell right away her lips were super soft, fragrant, and sweet.
I couldn't resist leaning in and kissing Rachel, her sweet saliva bursting in my mouth.
So soft, so fragrant, so sweet, so delicious.
I sucked on Rachel's full lips, drawing in the sweet saliva from her mouth.
I extended my index finger, aiming for her small orifice, wanting to penetrate.
Rachel quickly grabbed my hand, pushing it away while pleading.
"Don't penetrate me anymore. I'm begging you."
"But your performance with Samuel just now was impressive. How about giving me a turn? If he can't satisfy you, why not spend the night with me? I promise you'll feel good."
"You saw everything?" Rachel's blushing face turned pale in an instant.
"Yes, but I didn't see enough, so why not do it with me."
With that, I took Rachel's hand and placed it on my erect cock.
"See, it's hard, it wants to fuck you."
As soon as Rachel touched my cock, she recoiled as if shocked.
"Nathan, listen to me. I am your brother's wife, we can't have sex, do you understand?"
She appeared very calm, but the way her eyes kept stealing glances at my cock betrayed her.
"If you stop now, I can pretend like nothing happened at noon today, and I won't tell your brother."
'Is Rachel threatening me? Isn't that like the big bad wolf saying it's wrong to eat sheep just because he hasn't eaten for days?' I thought.
Her actions actually made me feel like she was a little lamb wanting to be conquered by me and ready to be devoured at any moment.
In that case, I might as well have some fun with her.
"Fine, we don't have to have sex, but you have to agree to one condition."
"What condition?"
"Let me touch your breasts."
I stared straight at Rachel's perky breasts, feeling like the next moment these snowy white breasts would melt under my passion.
The image of her breasts swaying while making love in the morning was still fresh in my mind, how could I easily let her go now?
She was wearing a light yellow silk slip dress, with a matching shawl draped over her shoulders.
A thin rope was casually tied under her chest, completely mismatched with those large breasts. It seemed like the rope couldn't support those two breasts, as if they would pop out any second.
"Don't even think about it!" Rachel glared at me.
She immediately covered her chest with her delicate hands, afraid of revealing even a hint of her breasts to me.
"Then let me penetrate your vagina."
