Sister's best friend Pt. 1

The seduction of my sister's best friend.

My name is Jack and I live with ny sister in an apartment. My sister's best friend, Lavinnia, is staying with us for family reasons.
I walked in from a long day at work to see Lavinnia with her back turned to me in the kitchen. She had a skirt on so short I could see her cheeks peeking out.
"What's up Lavinnia?" I say casually.
"Oh! Hi Jack, uh i'm just fixing some pasta up for dinner." Lavinnia said as she nervously tugged at her skirt in an attempt to cover her ass."
"Great! You're an amazing cook!" I replied.
She blushed . "Th-th-thank you."
"So Sara (my sister) said she wont be home until pretty late tonight. so its just you and me." I said as I move closer to her.
she avoids eye contact and focuses on stirring the pot. "Yeah... anyway this is almost ready. So uhhhhh."
"Great! I'll set the table."

About 15 mins later, after eating.

"Alright what do you wanna do now?" I ask.
"Whatever you want to do." Lavinnia replies shyly.
"How about a movie?" I suggest.
"Sure!" She replies.
We sit down on the couch close to each other. I chose a rom-com i liked that i knew had a sex scene in it.
I draped a blanket over both of us and scooted closer to her, to the point where we were almost touching. I could tell she was uncomfortable, but I didnt really care.

When the sex scene begins I get horny and get a large boner. It was sticking out of the blanket and Lavinnia could definately see it. I reached my hand under the blanket and groped her ass.
She gasped softly. "Jack, no. We can't do this. I have a husband."
"Lets be honest, who would you prefer, me or your husband? Isnt he the reason why you are staying here?" I whisper as my hand moves up her thigh.
she didnt reply but instead whimpered softy.
"Jack this is my first time." She said barely audibly.
"Then lets make it one you'll never forget."

I kiss her deeply, our tongues intertwinning. I could feel the sexual tension growing. I removed the blanket and paused the movie. I reached for her tits and began gentally massaging them. She moaned softly, and let me take full control of her body.

I removed her shirt, leaving her with her sexy black lacy bra. I removed my own shirt, then my pants, then her skirt. We were now both in our underclothes. I slowly removed her bra, exposing her big beatiful tits.

Lavinnia moaned as a pinched and sucked her nipples. "Ooh yes, I need this." She moaned in pure delight.

After about 5 minutea of sucking and playing with her tits, I pulled out my cock.

"Have you ever sucked a dick before?" I asked.
She shook her head no.
"Well, no better time than the present!"
