Wicked Sister: Mommy's Girl

Note : This story is completely fictional!

 My girlfriend Deirdre have been gal pals forever. We're both 18
and her mom is totally hot. Mrs. Sims is a 37 year old brunette with
nice 34D breasts, killer legs & butt who I've lusted after for years.
She's very domineering and once caught my wayward older brother going
through her panties & things. She punished him & sent him crying home
to his dear sweet Sis for comfort. He's been my slaveboy ever since.
Now I'm sitting at my bedroom window watching Deirdre & her Mom in
the back yard sunbathing. My brother Jamie is tidying up the room as
usual and I catch him looking at them through the window. "Get back
to work you peeping tom!" I tell him. I then tease my naughty brother
by telling him how Deirdre is rubbing suntan oil all over her Mom's
shoulders, neck & back. "Ooh, and now she's undoing her bikini top!"
Deirdre knows I'm peeking at her and gives me a wink. "Now she's got
her top off and is whispering in her ear!" I continue to torment my
poor horny brother. Deirdre then rubs oil all down her Mom's back to
her round cheeks poking out of her thong bikini bottom. She squeezes
her buns and blows a kiss at me. I blow a kiss back at her and walk
over to my brother and escort him to the window. I sit him down and
give his pretty face a good slap. "You can watch, but don't ever let
me catch you with Mrs. Sims again OK?" Jamie gave me his word as my
devoted obedient slaveboy brother and kissed my hand. I then tied him
to the chair and sat on his lap. We watched in awe struck wonder as
Deirdre massaged her Mom's shapely tan legs with oil. Slowly, all the
way from her supple thighs to her firm calves to her pretty feet.

I gave my brother a good lapdance as we continued watching Deirdre
give her Mom a full suntan oil body massage. It was simply amazing.
Jamie was holding my hand inside my moist panties as I ground my butt
into the growing bulge in his pants. He was kissing my back & neck as
he fondled my breasts with his other hand. Deirdre now took her Mom
by the hand and led her topless back inside. That was it! Jamie and
I had the most incredible climax together as I guided his hand to my
clit while he came in his pants. We caught our breath and looked at
each other dumbfounded. I gave my brother a playful smack and told
him to finish up in my room. I had to go over to get something that
Deirdre borrowed from me. I can't remember exactly what but I'm sure
I'll think of something when I get to Deirdre & her Mom's apartment.
And my devoted obedient slaveboy older brother will be waiting for me
to tell him all about what we gal pals get up to together. I'll tell
him only if he continues his slavish devotion to me. You must excuse
me right now. I have a date with Deirdre her Mom..............later.
