Chapter 13 – The Lessons Continue

Over the next few weeks I almost always had one, or more usually two, girls in
my bed each night. We continued our sexual activities but as is often the case
the tempo slowed down a bit. Many nights it was just cuddling and some gentle
kissing. Occasionally Ashley would decide she wanted to do something new and
Tara would sleep in her own bed. Tara wanted it to be just her and I when we
had intercourse but one Friday night she agreed to allow Ashley to come in and
watch. That night was one of the most erotic nights I've ever had. Tara had me
lay on my back and she got on top. "So Ashley can see what happens." was
Tara's explanation.

Tara had got used to having her clit stimulated and if I didn't do it, she
would do it herself. She loved it when I lightly pinched her nipples and if I
ran a finger over her anus. That night I chose to do both of those while she
was playing with herself. I happened to look over and saw Ashley with several
fingers working on her own clit and pinching her own nipples. That picture was
all it took to make me cum and cum I did. As soon as I started to cum, Tara
joined me and came herself.

Once we'd come down from our high, Tara pulled up off me. I was astounded to
see Ashley lean over and take my cock into her mouth. She'd seen Tara giving
me a blowjob but had never done it herself before. Once my cock was clean she
saw that there was cum on my stomach and on my legs where it had leaked out of
Tara. Ashley started to lick all of that up and without saying anything moved
so that she could lick it off of Tara's pussy lips. "Your stuff tastes good,
Daddy." she said.

I looked over at Tara who was looking shocked. "Are you all right?" I asked
her.

Tara nodded her head. "Dad... I didn't expect that and... and... I don't know
what." she said.

'Time for a quick discussion about lesbian sex' I thought. "Girls, let's talk
about what Ashley did, and no Ashley, it's not wrong." For the next few
minutes we talked about lesbianism and I tried my best to answer their
questions. Finally I had to stop as the questions were getting into areas that
I didn't know about. "Look, if you want I'll phone Grandma Mabel and see if
the two ladies can talk to you tomorrow. They can come over here and I'll go
to the office for a couple of hours. When you're ready you can give me a call
and I'll come home." The girls started looking at one another. "Get off me
please sweetie." I asked Tara and then went into the bathroom to clean myself
up. I took my time, listening to some whispering. Once the whispering stopped
I returned to the bedroom.

"Okay Dad, can you do that for us?" asked Tara.

"Okay, give me a minute." and I went off and called Mabel. She said she would
call Helen and see how quickly they could get organized. A few minutes later
she called back to say they'd be over at about 10 the next morning.

I was waiting when Mabel and Helen came over. "The girls are up in the master
bedroom. I'm going into the office. Take all the time you need and one of the
girls will call me when they're ready for me to come home." I said and went
off to the office.

I'd been gone for about 2 hours when Tara called to say I could come home.
When I got home there was no sign of the girls downstairs. I called and heard
an "Up here" from Tara. I went up looking each of the girls' rooms but no sign
of them. When I got to the master bedroom I was greeted by two naked girls
with wet faces. "Look Daddy" said Ashley as she dove back down to continue
eating out her sister. I looked at Tara to see that she was following suit.

Finally the girls came in each other's mouth. Once they'd relaxed they started
to tell me what had happened. "Now Dad, you remember what you told us about
not talking? Well the same rule applies to you." Tara said. Here's the girls'
story:

Mabel and Helen came into the bedroom and immediately started hugging and
kissing the girls. At first they were a bit afraid but soon warmed up to the
grandmas' actions. At some unseen gesture, both grandmas stopped, got off the
bed and stripped. "I was shocked, Dad." Tara told me. Grandma Mabel took Tara
by the hand and led her off to Tara's room. When she got there, Mabel lay Tara
on her bed and joined her, playing with her breasts while giving her full
tongue kisses. Soon Tara said she could feel Mabel's hand down on her pussy
and shortly thereafter she felt a finger on her clit. When Mabel urged Tara to
suck on her nipples, Tara complied.

Suddenly Tara felt Mabel get up and move to the side of the bed. She reached
over and moved Tara so her pussy was right at the edge of the bed and after
putting her heels up on the bed, Mabel got down and ate Tara out. "It was the
best I've had, Dad." she told me. When Mabel asked Tara to do her, Tara
couldn't wait. Finally Mabel and Tara went back into the master bedroom where
Helen and Ashley were just cumming.

Ashley said that she and Helen had done much the same thing as Mabel and Tara.

Once all four were relaxed, the grandmas told them of their history. The
grandmas had grown up as neighbours and with no other kids their age nearby,
soon became fast friends. Both were quite shy and were afraid to talk to boys
or to let them know that they were interested in going out with them. One
raining day they were in Mabel's bedroom and started horsing around. Pretty
soon, they looked at one another and without saying a word, got up, took off
all their clothes and got back on the bed where they started kissing and
petting one another. This continued even after they went off to college. In
college they met Paul and Harry and soon had sex with their future husbands.
In spite of this, the two women got together often and had sex together. Even
after marrying they carried on their relationship. To this day, they've not
told their husbands and as far as they can tell, their husbands are unaware of
their relationship.

Tara said that for the rest of the afternoon, Helen and Mabel continued to
play with the girls, switching partners from time to time. Towards the end of
the day the grandmas told the girls that girl-girl sex was normal between
sisters and that they shouldn't be afraid to try it. They then got the girls
to go and have sex with each other. "I finally understand why it's called
'sixty-nine'." Tara said with a smile. Once the ladies left the girls phoned
me and went back to enjoying one another and waited for me to come home.
"We're going to try it again." Ashley told me. I just smiled and nodded.

Over the next year things continued with one or both of the girls in bed with
me most nights. On some occasions the girls informed me that they were going
to have a 'girls only' night and I knew they'd be eating one another out. I
continued to fuck Tara but in spite of Ashley's pleading with me to fuck her
also, I wouldn't. On night I had to put a stop to the asking. "Sweetheart, you
know I promised that I'd do things to you the same as I did with Tara but only
once you've reached your thirteenth birthday. I'm not going to bend from that
rule. Okay?"

I could see that Ashley wasn't happy, but she nodded and from then on I heard
no more requests. One day when the girls had told me they were having a 'girls
only' night, I got a call from Mabel asking if I could come over after supper.
I asked if something was wrong but was told, no, she just wanted to chat with
me. I was left wondering what about, but after supper and telling the girls
where I was going I headed next door to Mabel's. When I rang the doorbell and
walked in I was greeted by both Mabel and Helen. This didn't surprise me as
the two ladies frequently visited back and forth.

"Hi David," Helen said, "Mabel suggested I come over to as we'll likely both
be involved in this." I looked at Mabel and raised my eyebrow in a question.
"Have a seat while I get you a coffee. Helen and I need to talk to you." I did
as requested and after the coffee was delivered and Mabel had taken her seat
again, she started to explain the reason for the 'meeting'.
