My mom and dad have an unusually large sofa, which is how my sister Liz and I ended up making out on it.
We were making out with the Lees from next door. I was making out with Jenny, and Liz was making out with Dan. Our parents were down at the shore for the summer and we had jobs and money and a car and that great big sofa. Seriously, that thing was wide enough to sixty-nine side-by-side on it without fear of falling off. And it was long enough that both Liz and I could lay with our feet at the ends, heads in towards each other, and still have room between us for a tray of beers and popcorn.
We had grown up with the Lees. They had always lived there, and we moved there when Liz was five and I was three. Dan was Liz's best friend when they were little and Jenny was mine, until we switched some time around middle school. We weren't quite as tight through high school, and had more or less dropped out of each other's lives through our first years of college. But this summer, it turned out we were all in town. We had boring jobs, Liz and Jenny at the mall, Dan at a housing development mowing lawns, and me scooping ice cream at an outdoor shack by the lake. Dan was 21 and could buy liquor, and Liz had a good connection to get cannabis edibles. And we were four pretty good-looking kids. If any of us had boyfriends or girlfriends at college, and we all did, they were a long way away.
So that summer night, we all were on the couch, and in the dark while we watched the movie, with no real discussion or plan, I started making out with Jenny, and Liz made out with Dan. Just kissing. Hugging. Stayed sitting up. Just a fun, low-key make-out session. When the movie ended, the Lees went home. Liz said, "Did you like making out on the couch with your sister?"
I gave her a look of total confusion before I figured out how she'd meant it. When the penny dropped, it must have shown right on my face, because Liz cracked up hard.
Another night, a week or so later, it was just Jenny and I alone. We were watching a movie, and Jenny said, "Why don't you sit a little closer, Art?" When Liz came in from her job about an hour later we were both buck naked and fucking on that big sofa. Jenny had her legs up on my shoulders and I was pounding her, deep as I could get. I didn't have a condom that night so I pulled out and shot cum all over her stomach and up on her tits. I looked over and there was Liz, leaning on the door frame and watching. She wasn't masturbating or anything, but she wasn't looking away either. She winked and walked by the couch, into the kitchen.
A couple of nights later, Liz came into the living room late and said that she'd been fucking Dan over at his place while Jenny was working a shift at the department store. She told me all about it. It got me kind of hot to think about it, and it took conscious effort not to jerk off right in front of her. As it was I rearranged myself a few times. Liz saw, and teased me that I was getting too aroused and she would have to stop telling the story. She had dropped her bra and panties on the couch next to her, and I could see her nipples getting hard through her t-shirt as she described how easy and fun it was to seduce Dan. When she told me that he'd cum in her mouth while she blew him, that was enough for me, and I excused myself to jack off.
The next night, I went for a moonlight walk with Jenny, and ended up pulling her shorts to her knees and eating her out from behind, up against a tree by the local golf course. When I got home around two o'clock in the morning, Liz was watching TV and I told her all about it. She told me about how Dan had fucked her in the back seat of Mom's car, and mall security had almost caught them. While we listened to each other's stories, we sort of idly touched ourselves through our clothes. Eventually I excused myself to jerk off and collapse in bed.
This sort of two-stage evening became the summer thing for us. We'd have sex with Jenny and Dan off separately, then come back and compare notes. It was really nice. Sometimes we would all eat dinner together and then separate into couples at the two houses. After a couple of hours of making out and fucking, we would walk back home across the adjoining back yards.
If it was Dan and I and we happened to cross at the same time, we would high five without speaking, then crack up. I remember leaving Jenny naked on her couch, and then Dan passing me right at the Lee's sliding door. Jenny got no chance to get decent. It probably gave Dan a good thrill, I thought, and the next night I hustled home a little early to try and catch Liz before she got her shirt back on. No luck.
One night Liz's pants and underwear were on the floor, and she had a blanket over her lap. She told me about how she'd done something or other with ice cubes to Dan, and I hardly listened, because of where she had her hand moving under the blanket while she told me. I got so excited that night, that I accidentally on purpose let my cock stick straight out through the fly of my boxers. And I gave it a few strokes there, gentle and light, but right out there in the open. Liz excused herself and went off to bed, wrapping the blanket around her. I sat silently outside the door of her room and listened to her cum. Then I went to bed. I had so much lust that I couldn't even cum, and I slept fitfully that night.
One very hot night in July, we all played strip poker together. But once the girls were down to their bras and panties, Jenny pulled me back to her house to fuck her. Literally. She grabbed my arm and pulled me up off the carpet and out the door. After we finished fucking, settled down and were just kind of glowing and stroking each other, I asked, "Does it turn you on to be doing sexy stuff in front of your brother?"
"Don't be gross," she said.
"You don't have to be embarrassed about it," I said. "I totally got turned on watching Liz unbuttoning her blouse, and sliding that skirt off. And you can't fool me, either. You were really hot and bothered tonight. You're dripping."
"Uh... I guess it kind of does rev my motor," said Jenny.
"Why don't we just all stay in the same room sometime instead of going to separate places? I'd love to see Liz fuck Dan while I fuck you."
"That might be a little too real," said Jenny.
