My Best Friend’s Sister part 7 [MF]

I’ve been seeing my best friend’s sister for about 6 months without him knowing about it.

She had always been my friends little sister until she came back from college a stone cold fox and we’d been flirting for a year before a drunken night gave way to a threesome with her and my friends’ ex.

After that we started fucking on the regular and her kinky side came on like coffee – hot and strong!

We were getting busy everywhere when her Roomate, Marie, found out which turned out great because Marie started joining in and we became kind of a throuple. My best friends sister, Stephanie, only had one rule, that I didn’t have sex with Marue when she wasn’t there.

This wasn’t an issue until Steph went out of state to visit her sister and Marie seduced me and we had a sex fueled weekend.

But Marie took a photo of us in the act without me realizing.

Steph came back nine the wiser, but Marie
has been using the photo to blackmail me.

Unless I keep sleeping with her on the side of our throuple, she’s going to tell Stephanie and her brother about everything.

I’d been walking on this tightrope for 2 months until we got to this weekend…

Strap yourselves in folks –

Stephanie and I went camping this weekend.

We arrived at the campsite, set up our tent and camping equipment and walked down to the beach for a swim.

She was especially horny today. She lead me out into the ocean and pulled my shorts down and hoped oh my dick right there with dozens of people on the beach 30 feet away.

She rode me subtly and gently until she came about 5 minutes later.

She hoped off and jerked me in the ocean and I came in 30 seconds.

We went back to the camp sight and showered together. She asked me to watch her as she stood under the shower and started playing with herself until she started squirting.

She was making noise but she didn’t care.

She came again hard and her legs started shaking.

We dried off and got changed and went to dinner.

She was extra freaky tonight, flashing her tits at our dinner table when the waitress had just walked past, almost like she wanted to get caught.

The waitress was a petite blonde. He hair wasn’t very long, only enough for a high pony tail.

Stephanie kept commenting on how cute she looked and would love to get with her.

Stephanie is a very kinky girl but it normally only comes out privately. She was being very nonchalant as she rubbed my dick through my pants under the table.

After we had our entrees, I looked at the desert menu while Stephanie went to the restroom. After 10 minutes and her still not returning, I went to look for her.

I was waiting outside the woman’s restroom when an older woman came out shaking her head in disgust.

As the door closed I heard a familiar moan.

I poked my head in and saw Stephanie’s shoes under the first stall, she was kneeling down in between someone’s legs.

“Stephanie?!” I whispered.

“Is that you?” She responded.

“Yes! What are you doing?”

She laughed “come in and see.”

I checked the coast was clear and slid into the bathroom and opened the stall door.

My eyes locked with our blonde waitress.

Her white button down was open and cute B cups were popping out of her pulled down white bra. Her pants were around her knees.

Her blonde haired pussy was hidden behind Stephanie’s head as she ate her out.

Stephanie turned and smiled and stuck her tongue out suggestively.

She beckoned me to come in and shut the door before going back to eating the waitress out.

The waitress smiled a guilty smile.

She looked to Stephanie and Stephanie smiled and nodded up at her.

Without a word, the waitress reached forward and pulled me towards her with my belt.

She unbuckled it and unzipped my pants and pulled my 7 inch cock out and started sucking.

Stephanie pulled her dress down and let her perky tits out and started playing with her nipples.

The waitress came at the same time I did and I came all over her face as she moaned in pleasure.

Stephanie laughed and clapped at our delight and kissed the waitresses cum stained lips.

We got back to our table and paid the check. No desert needed.

We went back to our campsite and pulled out a bottle of tequila.

We were laughing and making out and enjoying each other’s company.

A car pulled up to our campsite and out hopes the waitress. Stephanie had invited her to come party after her shift.

We played truth or dare as we got to know each other.

The waitresses name was Delanie and she was working her way through school.

She had broken up with her long term boyfriend a month ago and was on the hunt for some fun people to play with.

And she had found us.

We drank and sucked and fucked til the early hours of the morning. Stephanie was insatiable. I had nothing left in the tank after we had fucked 4 times.

I was exhausted and ready to pass out when the waitress said goodbye and drove off. It was 5am.

The campsite was quite as everyone was sleeping.

Stephanie came into the tent and cuddled up next to me.

We shared a sweet kiss.

“That was fun.” She whispered with a grin.

“Mhmm” I replied, satisfied and half asleep.

The next day we packed up the camp and headed home.

We were still recounting the weekends festivities as we pulled off the highway and toward her house.

“I feel a little bad about replacing Marie with Delanie though” she said after I mentioned our waitress love fest.

“Oh yeah?” I replied.

“Yeah. It’s only been you, and Marie before tonight.”

“Except for our first time with Tori.” I reminded her.

She giggled. “Yes, but that was before we all decided to be together.”

“I mean, it’s always been pretty loose with our promiscuity. But as long as two of us are involved, I think it’s okay.”

“You and me, you mean.”

“Huh?”

We pulled into her driver and I put the car in park.

“You said ‘two of us’. Not you and me.” She stated.

“That’s what I meant.”

Marie heard the car and came to the front door and waved at us. I waved back.

Stephanie looked at Marie. She looked at me. Something clicked in her brain.

“Did you have sex with Marie without me there?” She asked plainly.

“What?”

“You heard me.”

To be concluded…
