So assuming you've read my first encounter with my sister, let's call her Anne, that was the start of a sexual relationship spanning a couple of years that I still, to this day, recall fondly and consider one of my best. It didn't happen immediately, in fact, our interactions were a little stilted at first, but over a few weeks, as I'm about to explain, they got much, much, better.
To give you a picture of what Anne looked like, she was at the time about 5' 2 and very slim, in fact, into her thirties she could wear children's clothes and avoid paying VAT. She did however have a nice full bust, I'd now guess she was 34/36 C/D then, with fairly normal hips, making for a nice hourglass figure. She was blonde but wasn't stunningly pretty. She did, however, know how to dress, especially exploiting her full bust, and would turn heads often.
On the other hand, I was not only thin, but would be considered scrawny. I was 5' 4, weighed about 7 st, and could suck my stomach in so far that I could close my hands around my waist touching finger and thumb tips. I wasn't an attractive proposition for most girls, which contributed to my surprise that she had previously forced me to eat her out.
As mentioned above, things had been difficult since she'd forced me. I, for instance, now loved the thought of it happening again and couldn't stop thinking about it. She, however, clearly felt differently as she had hardly spoken to me. Whether it was guilt, shame, or anxiety at the prospect of me grassing on her, I don't know.
One major change that surprised me, to be honest, was that she would now come through my room to the bathroom at night, naked, or at least just in panties (if you don't understand why she had to come through my room, read my
first encounter with her
as it explains it).
Her naked tits were a typical late teens not fully developed woman pair, with puffy nipples and the last traces of the conical appearance that late-teen girls have, or at least that's what the two or three pairs of teenage tits I'd ever seen, looked like.
I loved them, and couldn't get them out of my head, day or night. These almost nightly trips to the bathroom though, bouncing them around as she came through my room, were more than making up for not having seen them in our earlier encounter. Even when she had panties on, they were lacy or see-through or similar, always sexy.
I was already obsessed with tits, my cousin had seen to that, showing me plenty from porn mags that he sneaked from his dad's stash. I don't know if this new show from Anne had made me more obsessed, but it certainly didn't diminish it, that's for sure. What I do know is that I would literally lay awake for hours, waiting for her to skip through my room to the bathroom, her tits bouncing on the way, deliciously.
It hadn't immediately registered that she'd sometimes leave the door partly open too, despite being in there to pee. With the bathroom light shining bright, and my bedroom light off, this enabled me to see clearly as she took a pee and wiped herself, and she always faced the door as she did it so I got a good eyeful.
I was even able to move for a better view without her noticing my movement. It also occurred to me that I could stroke my cock whilst watching her and she wouldn't see. So, many a night found me with cock in hand, ogling my sister's tits as she spent a penny in the bathroom, then pretending to be asleep once she reached my door and passed through my room, and finally, furiously, rubbing one out as I continued to picture her tits and recall the scene in the bathroom from a week or two earlier.
Life was good; and it was about to get better.
Almost every Saturday, as a tradition, we visited our grandparents on our mother's side. They lived about a thirty-minute drive away and it was quite common for us to go there for Saturday afternoon even into adulthood. The three of us would be dropped off, Anne, Andrew, and I; then Mum and Brian would go do some shopping, run errands, etc, and once done, pick us up.
A couple of weeks had passed without visiting them since Anne and My bathroom adventure. We were therefore quite pleased when mum announced that we were heading over there late one Saturday afternoon as we hadn't seen them for a while.
