(for the earlier parts of the story, see December Swing Club with Chris and Lesli - Part 1 and December Swing Club with Chris and Lesli - Part 2). There is still much more to come!Here we were in the cowboy room at the club. Brenda and Lesli, both naked, were laying together on the bed, waiting for me to bring them the toy they had been waiting to use for the first time. This is what I brought them. The Feeldoe is essentially a dildo that can be used in the same way that a strap-on dildo is used by one girl on another, except that the wearer can usually do without the strap by inserting the bulb into her pussy, which holds the toy in place and allows the wearer to fuck the other girl. As you would expect if you have read earlier posts about Brenda's and Lesli's respective sexual roles, Brenda was to be the one fucking Lesli, not the other way around. Brenda was on her hands and knees between Lesli's thighs, bending over her. I lubed up the toy and handed it to Brenda as she reached down under her to insert the bulb. Chris came over and held Lesli's thighs as Brenda reached down to guide her "cock" into Lesli. Their giggles of nervousness immediately gave way to sighs as the large purple shaft slid into Lesli's pussy. Although this was something Brenda really had no experience with, she slowly started working her hips, getting the feel for the rhythm. It was a somewhat strange but unbelievably erotic sight to see her on top of Lesli, fucking her in missionary position just as I would fuck Brenda. And while it may have started out a little unfamiliar, in a very short time she really got a groove, riding high up on Lesli, grinding down with each stroke. The Feeldoe has grooves that stimulate the wearer's clit; whether it was that, or the sexual high of fucking Lesli in a way they had both fantasized about for quite a while, in any case Brenda was clearly just as turned on as Lesli was. I watched her ass with fascination as she fucked Lesli and ground into her, and listened to the moaning and heavy breathing from both of them. I became aware that we had attracted a crowd again, looking through the open doorway at the girls. Brenda was holding herself up over Lesli, who was reaching up to cradle Brenda's face, kissing her face and her full breasts. Lesli was whimpering and moaning, and Chris, who was still standing behind the girls, began caressing Lesli's thighs, and started teasing Lesli's ass. Brenda continued her grinding strokes as Lesli began to climb toward an orgasm. As she got closer, Chris started fingering Lesli's ass more directly, and I could see her thighs beginning to tremble as Brenda started fucking her harder. In between moans, I heard Lesli whimper to Brenda, "You fuck me so good!" Brenda simply responded with a pleased "MMMMMmmmm" between her own heavy breathing. In a few more seconds, Lesli's whimpering intensified, and as Brenda ground deep into her, Lesli pushed over into a hard orgasm. Brenda rolled off of Lesli, as they both lay together panting. After a minute or two, they started giggling, especially when they realized the audience they had for their first dildo fuck!I crawled up on the bed next to Lesli, and began to kiss her breasts and neck. Then I got in between Lesli's thighs where Brenda has just been, drizzled some lube on my very hard shaft, and slid into Lesli's well-fucked pussy. As I slid slowly in and out of her, I bent down to nibble and nuzzle her nipples, and almost immediately she was sighing with pleasure again. Brenda had rolled over on her stomach to watch us, and Chris maneuvered up behind her. "Wow, I don't know if I can take any more after the fucking you gave me a little while ago!" But Chris paid no attention, and pulled her hips back so she was bent over the edge of the bed, and slid into Brenda again. Very soon Brenda moaned, "OK maybe I can!" I could hear how wet her pussy was as he slapped against her. After a bit Brenda crawled up further on the bed and turned over on her back, and pulled Chris up toward her. He slid inside her and began to stroke slowly. Brenda wrapped her legs around his waist, and murmered to him "Fuck me hard! Please fuck me harder! I pulled back out of Lesli, and grabbed her hips and turned her over to doggy position as Chris pounded Brenda, drawing deep "uunnnggghh" sounds from Brenda. I slid slowly into Lesli's pussy; as I gradually buried myself deep inside her, she twitched just a bit, and managed a quiet "Careful!" I tried to go easy, but wasn't sure if I was hurting her or not. Brenda's moans were more and more intense; I looked over and her legs were spread wide as she dug her nails into Chris' back, lost in the pleasure of a good hard fuck, and climbing again toward orgasm. She reached a little mini-peak, and just then Lesli jumped away. "I've gotta pee!" she exclaimed, although I think it might really have been that she was a little uncomfortable with the penetration in that position.Brenda climbed off the bed to go to the restroom with Lesli, leaving Chris and I there. Chris decided to investigate what was going on the next room where we had heard some interesting sounds, so I was sitting by myself in the room for a minute. A woman, who was apparently one of the people still enjoying watching our activities, stood in the doorway watching me as I sat on the bed, still hard from my interrupted activities with Lesli."Where did everyone go?", she asked. "Oh, they'll be back... pee break!" I said. The woman was a bit older, wearing a short black dress and quite a decent figure. "Mmmm, that looks pretty good!", she exclaimed as she looked down at my shaft. "Do you need a fluffer?" The expression on her face as she looked at my cock gave me the impression she'd be more than happy to drop to her knees, and I thought about it for a minute, and then decided since this wasn't something Brenda and I had really discussed, I'd better decline. I thanked her and said I'd just wait for the others to return, and she responded, "Well just let me know!"(to be continued)
