Spending the summer at mothers in laws place

My wife sprung a helluva surprise on me at her mother's beach house

"We are going to spend most of the summer at my mother's beach house!"
exclaimed my 28 year old wife, Lori.  She is a slender gal with 32 - 24 - 36 measurements, curly brown hair and brown eyes to match.  When she is naked, her 32 B cups are tight,  with pink nipples and she has a nice shapely ass and trimmed brown pubic hair on her pussy.

I wasn't thrilled as I didn't think highly of my mother in law.  She is a retired hippie, who I think doesn't take life serious enough.

I knew better than raise a fuss, so I began packing for the three hour drive to the South Texas beach town of Corpus Christie.

When we arrived, mother in law, Shawna, opened the front door of the beach house and welcomed us in with big hugs, much to my chagrin.

Shawna, 50 years old, a mixture of brown and grey straight hair, had a decent figure for her age.  38c tits, a bit of old age sag and still good looking bubble butt despite her half century age.

Shawna made dinner for the three of us and afterwards, Lori and I made our way down the hall to the guest bedroom.

As we lay in bed naked, Lori whispers,

"I have a surprise for you tomorrow night".

"Surprise?  What is it?"

"It wouldn't be a surprise anymore if I told you now."

So to keep me happy despite not giving me any clues, my wife gives me a blowjob, swallowing every last drop of cum.

The next day went by with not one clue as to what my "surprise" would be.  My wife seem to be in a better mood than I can recall ever seeing her in.  Shawna seemed a bit more chipper as well.

As evening approached, my curiosity was really starting to ramp up.   We enjoyed a nice dinner with my mother in law, then retired for the evening.

I undressed as usual, climbed into bed, when I noticed my wife had disappeared.   She walked back into the bedroom carrying leather restraints and a blindfold.

"Are you ready for your surprise" She asked?

I was a bit intimidated as we had never tried any kind of bondage play, but I wasn't going to shy away from this challenge.

"Yes, I am".

She tied my wrists to the headboard and then tied my ankles to the bedposts at the end of the bed.  Much to my surprise, she blindfolded me and still turned off the lights.

Smooth jazz start playing .

I was really starting to enjoy the situation when I felt a hand start stroking my cock.  I was getting harder with every stroke.  After a few minutes, a mouth replaced the hand.  The mouth slowly took in every inch of my erection.  My wife had always struggled with deep throating my cock.  I was roughly 6 inches when hard but that was just a bit more than my wife could handle, so I never complained because she was still very good at getting me off during blowjobs.   The mouth kept deep throating me, and then backed off.  Then all the way down again.  I knew if this continued, I wouldn't last much longer and then her mouth stopped.
I heard a bit of shuffling on the bed, then the weight of a body was on top of me.  I felt a hand wrap around my erection and I realized it was guiding my cock into a warm, wet pussy.
The person on top of me (im thinking it's my wife) started riding my cock.  Up and down, up and down.  I heard a low moan as that pussy was enjoying having my cock inside.

I thought the moaning sounded like my wife, but she was not really the vocal type.

Suddenly the fucking stopped.  The body lifted off me, but they just turned around and impaled themselves back down on my hardon.

They slowly rode me for a good ten minutes at least.  I felt the pussy start riding me faster, then a little faster.   Now I was to the point of no return.  I let out a moan

"I'm going to cum"

I felt the pussy muscles really clamp down on my cock.  I don't remember my wife ever doing that while on top but I wasn't too concerned as I started to fill the pussy with my sperm.   I felt squirt after squirt  release inside until I had no more to give.

The person on top, started slowing down until she came to a stop, just resting on top of my body.  Those pussy muscles continued to squeeze my cock. Relax and then squeeze again.  I was in heaven and didn't want this night to end.   The squeezing finally stopped.  Whoever was on top, raised up and got off.

I heard my wife ask

"Did you like that honey?"

"Oh yes I did"

Then I asked "why haven't we done this before?"

She said "doesn't matter, we will however, do it again soon if you really enjoyed it".

Next thing i know, blindfold came off and I was released from my restraints.

She didnt turn the lights on, just climbed in bed with me to cuddle and fall asleep.

The next morning I woke up to find my mother in law naked in bed with us.  I was quite surprised.   She and my wife had scooted down to be able play with my cock.
Shawna then opened her mouth and deep throated me.

Suddenly, I realized who was pleasuring me last night.  I looked wide eyed at my wife who had the biggest smile on her face.

Then my mother in law straddled me and slowly slid down onto my hard cock.
I felt her pussy doing the same squeezing technique as what I felt last night.

Lori then said

"You said you enjoyed it last night, how do you feel now"?

I was speechless for a moment, then my wife leaned in to give me the most erotic  French kiss.  So hot and sweet it was.

"My mom and I wanted to find a way for you to like her better.  I hope you do know."

I looked at Shawna who was smiling while still on top of me with my cock buried in her pussy.

"Yes, i think I like her a hell of a lot better" I laughed.

Lori  then said

"Oh good, now are you ready for another surprise?"

I don't know what could've been a better surprise than that but of course I was ready.

She and her Mom stood up, faced each other and began making out.  Then Lori laid down on her back, on the bed.  Her mom turned around, got on top and they began performing a sixty nine on each other.

I watched as they both proceeded to make each other orgasm while licking each others pussies and clits.  They then flipped over so my wife was on top, thus allowing me to slip my cock inside her pussy doggie style and fuck her like I had never fucked her before!

Once I shot my load in her, we all collapsed onto the bed to catch our breath.

I knew this was going to be a summer like no other!
