We were quiet for a while, then Gail said softly "Scott, can I ask you a question?"
"Sure, what?"
"Last night, you were my first. Was I also your first?"
"You were," I told her. Well, technically anyway: the previous night Missy had snuck into my room and sucked my cock, letting me eat out her pussy. I hadn't known it was her until this morning, when I had my hand less than an inch from her bald and wet pussy -- neither encounter being something Gail ever needed to know about.
"Oh, I see you remember it fondly," Gail said, and I realized she was staring at my crotch. Of course losing my virginity to my twin sister was one of the high points of my life, but this particular erection came from thinking about what I'd done with Missy.
"Of course I do," I told Gail.
"You know," she said, "Mom and Dad sent us here to buy school clothes, but there's no reason we can't stop off at the bikini shop. There were a few I couldn't show you the other day."
Well,
that
answered the question neither of us was discussing: whether what we'd done the night before was going to be a one-time thing. And whether my fucking Cathy meant the end of fucking my sister.
And just think, a week ago I was thrilled to have briefly touched Alison's bare breast.
We got to the mall, bought the requisite school clothing first, and locked it away in the trunk of the car. Then we went to Hot Summer Fun, and I settled in for what promised to be an interesting show.
And today, unlike the other day, I didn't have to pretend not to be interested.
First, Gail came out wearing a bright red bikini that seemed pretty conservative, though definitely flattering to her large breasts -- then she showed me how the cups could be adjusted from being so close together that there was no cleavage exposed t,o (as she called it) "Promise you'll bail me out when I'm arrested." She illustrated this, after making sure nobody was around, by moving the cups so far apart that I could see part of her aureoles. "Wow," I told her
.
She smiled and went back inside the dressing room. When she came out, she was wearing a one-piece that stretched so tightly against her crotch that it might as well have been a thong bottom. Above, two strips of nylon covered both of her breasts completely, but the "cleavage" went down to her waist. "nobody ever actually wore that in public," I said.
"No, but maybe in private. If we had a pool at home you wouldn't mind seeing me in this, would you?"
"Not at all," I said; though looking at the bottom of the thing, it didn't look at all comfortable. And speaking of which...
She saw where I was glancing, and answered my question before I asked it. "Cathy showed me how to shave down there before she left. She helped me a bit, actually; which might have felt awkward if I hadn't just, you know, watched her fucking my brother. Okay, one more."
She ducked back into the dressing room and a few minutes later said "I'm not sure I can come out in this."
"Oh,
that
sounds interesting. Can I come in?"
"Eh, screw it, here I come," she said, and opened the curtains and came out.
She kept her back to the dressing room, because the bottoms were little more than a string in back and exposed her whole ass.
On top, her aureoles were completely covered, but that was about it. She looked down at my crotch and said "I see you like it."
"You think?"
"Honestly, though, it seems to me anybody wearing this might as well just be topless. You got the time?"
I took my phone out of my pocket and checked. "Okay, do you want to see the movie after all? I think I'm going to buy the red one, so you go ahead and get the tickets and I'll meet you there."
When she caught up to me, she was wearing her cotton shorts as before but she'd replaced her t-shirt (and bra) with the red bikini top. She wasn't the only girl in the mall that evening wearing a bikini top as a shirt, of course, but I don't think anybody wore one better.
She smiled when she saw I approved.
Without discussing it first, we both made our way to the back of the theatre. It was empty enough here that once the lights went out, we'd be able to make out as if we were dating. I realized we'd fucked last night -- twice, in fact -- but we'd never kissed.
She pushed the cups of her bikini top just a bit further apart, exposing a little more cleavage. Well, now I'd just have to kiss her there too.
Just as the commercials were ending, just before the lights went completely out so the show could begin (and our fun could begin), we noticed somebody else coming down our row. As they came closer -- they were coming very close, why were they coming so close??? -- I noticed they were a couple about our age. The girl had long, jet-black hair, falling over a white, button-down blouse, and wore a denim skirt that couldn't have come down more than an inch or two below her panties.
Knock it off, I told myself, you shouldn't be looking at other girls when you're out on a date... um, with your sister.
