Ann and I arrived at Barb’s house after lunch that Saturday. I made a point of trying not to be alone in the same room with Barb, but in fact she seemed subdued from her usual flirty self. I wondered if she was feeling embarrassed about going too far with me on the phone.
After a long afternoon of packing, strategizing about packing, unpacking and re-packing, it looked like almost everything she wanted to move would fit into or on top of our SUV, so we’d be able to get it all to the storage place in one trip.
Almost. There were two boxes that just wouldn’t fit.
Barb pondered the situation, her hands on her hips. She was wearing scruffy clothes – a loose-fitting pair of shorts and a T-shirt ¬– but she looked adorable anyway. With her small breasts she didn’t really need a bra, and in the cool air outside her building it was clear she didn’t have one on. ‘Well, screw it,’ she finally said. ‘Put the two boxes on the front passenger seat.’
‘But then where will you sit?’ I asked. ‘The whole back is packed solid with hardly room for one of us to sit back there.’
‘It’s simple, Jake,’ Barb said. ‘Ann will drive, since she knows the way. I’ll get in the back first and you can sit on my lap!’
‘Very funny, Barb,’ I said. I’m six foot three and not skinny. The idea of me sitting on Barb’s little lap was pretty silly.
‘Well then I guess I’ll have to sit on your lap. Unless you think I’m so big and fat that I’d squish you.’
‘You don’t weigh a hundred pounds soaking wet, Barb. I think I can handle that.’ Even as these words were coming out of my mouth, I was regretting them. A flirty, sexy, scantily-clad Barb sitting on my lap for a half-hour drive was sure to be a very special brand of torture.
‘All right then,’ Ann said as she got into the driver’s seat. ‘You guys get in so we can head out.’
I got into the left rear passenger seat of the SUV and held the door open for Barb. After she got in and settled herself on my lap, she leaned back and whispered into my ear, ‘You’ve never seen me soaking wet, sweetie, but I think you will soon!’ So much for my theory that she was easing off on the flirting.
As the car pulled out of the driveway, Barb shifted herself a few times on my lap. ‘Let me get into a good position here, Jake. We’ve got a long drive and I want us both to be comfortable. There, that’s better!’ With her last wriggling shift, she grabbed the elastic waistband of her shorts and pulled them down to her thighs. Then she sat back, resting her naked ass on my crotch. ‘Is that comfy for you, Jake?’
Anyone looking at my face at that instant would have thought I’d just stuck my dick into a light socket. Barb had never done anything this blatant – or this crazy – before. My first reaction was to look up into the rear-view mirror to check if Ann could see anything. But I couldn’t see her face in the mirror, so I knew she couldn’t see mine. With relief I calculated that Barb and I were too far over to the side to be visible to Ann unless she adjusted the mirror. And since we were directly behind her, it would be hard for her to turn around far enough to see us.
Still, this was flat-out crazy. I thought about yelling at Barb to quit fucking around; if Ann looked back and saw what her sister was up to, that was Barb’s tough luck. I also thought about grabbing Barb’s shorts and pulling them back up her legs myself. But mostly what I thought about was what a sweet, smooth, beautiful ass my sister in law had.
Barb reached behind her, pressing her fingers against the crotch of my jeans. ‘Let me know if this gets hard for you Jake, and I’ll move so you’re more comfortable, OK?’
‘OK,’ I managed to choke out. It was getting hard already.
We drove along in silence for a few minutes. After a while I started to get over the shock of what Barb was doing. My cock was swelling up in my pants, with the associated effect that my higher brain functions started to shut down. I decided to enjoy this, and I put my hands on either side of Barb’s waist, holding her hips and feeling her firmly muscled stomach under her T-shirt.
‘It’s really great of you guys to help me out like this,’ Barb said, speaking so Ann could hear her in the front seat. ‘I just hope I can do something nice for you, real soon.’
I started using my grip on Barb’s waist to slide her slightly back and forth, causing her naked ass to rhythmically press against my hardening cock. Looking over Barb’s shoulder I could see down to her bare belly and the neatly trimmed triangle of curly brown hair there. I moved my hands over her skin, inching them forward and downward and then back again, creeping my hands towards her pussy and then retreating. I was thinking revenge; if she was going to drive me crazy, maybe I could drive her a little crazy too.
