 Just then the front door bell rings.  I look through the spy hole and see
Joan and her kids.  I open the door and invite them in.

   "Hi Joan," I say.  "Hi kids, they're outside,"

   The kids rip their clothes off as soon as the door is closed.  Adam
(10yrs) is sporting an erection it bobs in front of him reddened from
earlier exertions, Chris his (9yr) brother is soon naked as well his little
cocklet also shows signs of previous use and is semi-hard.  Chloe (8yrs) is
a beautiful little blond with hair almost down to her lovely tanned little
bum and her little pussy looks red and puffy.  7yr old Julie yanks her
shorts down and tugs her t-shirt off her little belly has dried glistening
cum stains on it.  Joan swats her little tanned bum as she races off with
the others naked as the day she was born.

   "Hi," Joan says.  "How are things?"

   I laugh "Our Postman has just made three deliveries."

   "What!" Joan says.  "I meant what have the kids been up to."

   "I know what you meant," I laugh.  "The Postman has just made two
deliveries into Sandy's little hole, and given her a white wash."

   "Wow!" says Joan.  "Did she enjoy it?"

   "Rode him like a cowgirl," I answer.  "Loved every minute seeing him
tomorrow for another load."

   "He's in his sixties isn't he?" Joan says incredulously.

   "Yeah!  But got a 10" cock," I tell her.  "And thick as her wrist."

   "Wow!" says.  Shaking her head.

   We walk down through the lounge and pass Chloe and my Brian fucking
doggy-style.  Brian tugging on her beautiful hair as he pounds her from
behind.

   "Randy buggers," I say to Joan with a wink.

   "Been at it since 6:30am this morning," she says.  "Heard Julie
screaming thought it she was having a nightmare instead found her on top of
Chris screaming as she came hard."

   Joan tells me she has brought toys for us to play with while we watch
the kids, and I smile and look into her bag full of various dildos and
vibrators.

   "It's gonna be a fun day," I laugh.

   We go to the patio in the hot sunshine and Sandy and Colin run over to
greet Joan with Julie and Adam tagging along.

   "Hi Sandy," Joan says cheerily.  "Heard you and the Postie got it on
today."

   "Sure did Auntie Joan," Sandy says happily.  "His cock is this big in
me," she indicates a mark on her stomach beside her belly-button.

   Joan laughs.  "Lucky girl."

   Joan and I strip off as the kids gather around Adam asks Sandy if he can
fuck her.

   "Course," Sandy replies.  "Sit down I want to ride you."

   Colin and Julie lie down on towels and are soon 69ing each other.

   Joan hands me a 10" thick looking vibrator and takes an even bigger one
for her and soon we are both buzzing as we stroke our engorged clits and
tease our hot boxes.

   Sandy sits on Adam's lap facing him and he kisses her small erect
nipples her little body is still covered in dried cum.

   Sandy takes a hold of Adam's 6" erection stroking it then rises and
shuffles until her little pussy is stretched just above it and slowly
lowers herself onto Adam's length.

   I push the vibrator into my pussy and immediately have a gut wrenching
fantastic cum followed by two more small one's I nearly drop the vibrator,
but Adam catches it with his free hand as Sandy rides him.

   "Thanks," I gasp.  Adam smiles and pushes the vibrator in and out slowly
and I strum my clit and I have another crushing orgasm just as little Sandy
has a big one mounted on Adam's erection.

   She moans and grabs his neck spasming her little belly rippling and
sweats dripping from her.

   Adam lets go of the vibrator and it drops buzzing to the ground as I lie
back gasping post-orgasm looking at Adam taking hold of Sandy's little bum
cheeks and his hips pumping rapidly into her.

   Within a couple of minutes he's shooting loads of sperm into Sandy

   "Here It comes Sandy," He gasps.  "God I'm coming gallons," he spurts
into her.

   Just then Joan comes by her own vibrator and lies back gasping for air.

   Just then Chris comes through and immediately starts licking out his
mother who grabs his little head pulling him tighter into her.  His little
hairless cock lolling on his thigh.

   Joan comes quickly again and lets go of her son's head and he comes up
smiling licking his lips.  Colin and Chloe joins us as we all pause for
breath.  The boys for the first time today are not erect and the girl's
little pussies are all red and puffy.

   Joan and I feel very comfortable naked around the kids although we are
older and soon we are all relaxed enjoying the sunshine chatting.  Sandy
shows Chloe and Julie that Joan's big vibrator is the same size and the
postman's cock.

   "God it must have nearly come out your mouth," Chloe gasps
absentmindedly rubbing her prominent little clit making herself shiver.

   "Did a bit," says Sandy enjoying the attention.  "But he was really
gentle but it really filled me and he shot loads into me,"

   "I'd love to try that," Chloe gasps her finger busy diddling herself.

   "He's gonna be here tomorrow," says Sandy.  "You can have his second
load if you like."

   "Can I," Chloe gasps nearly coming again.

   "Sure if your mum says it's okay," Sandy replies ignoring her friend
frigging herself.

   "Oh!  Oh!  Ah!" Chloe gasps giving herself orgasm thinking about the
postman's cock.

   "Can I mum," she gasps coming down from her orgasm.

   "Sure dear," Joan says.  "If Sandy or her mum doesn't mind I'm sure the
postman would love to fuck you."

   "Cool," Chloe says picking up the big 10" vibrator.  "Who's gonna help
me practice?"
