Best weekend ever!

We just had the most amazing weekend ever with Heidi and Dave [HDmichcpl] at our lakehouse in Michigan. We had played once before with H&D at their house but it was mild and low-key. Since then, we had exchanged many messages, texts and phonecalls about meeting again... especially the girls. Since the weather was going to be nice for the last time this year, we decided this was the time. The girls must have worked it out ahead of time but they both dressed very sexy... even slutty... the whole time [at least when they weren't naked. Even when we went out to the local bar near our cottage. It turns out Heidi had had a fantasy about being a slave for a weekend and was finally ready to go thru with it. As soon as we arrived, Dave announced that Heidi was free to be used by all of us for the next two days and she couldn't say "no" unless she used a safe word... she never did. I wasted no time and stripped her, licked her and then fucked her as fast as I could. Amy started a little slower kissing and hugging Dave while they watched us but by the time I came with Heidi, Amy was on her knees sucking Dave. I ordered Heidi to get under Amy and start licking her. She had been very shy about going down on Amy the first time we got together but time she just said "Yes Sir" and slid under Amy's dripping pussy. Amy didn't last long and came quickly while she was still sucking Dave. I was impressed he'd lasted that long and he quickly got Amy on her hands and knees and fucked her doggy style under he sprayed his load. While they fucked, I had Heidi suck me back to life and then I made her lick Amy's full pussy while I fucked her from behind. Dave filmed this part and if I can figure out a way, I'll post it for friends. The whole weekend, Heidi never said no ... even to some pretty daring orders... We all went hiking and made her strip to nothing but her sneakers. Only one couple saw her on the trail, but just giggled. Dave said "you can have her if you want her" but they just kept going. Later that evening we took her back to the bar dressed in nothing but a crop top, short skirt and black boots. She was almost in a trance the whole time ... glassy-eyed and flushed cheeks... but she never said "no." Dave even took her out to the car, fucked her, and then brought her back in. He told Amy to stick two fingers into Heidi's pussy and then lick them... which Amy suprised me by doing without hesitation. The rest of the night and Sunday morning was spent fucking, sucking, showering and repeating. Dave ordered Heidi to ride home naked [with just a blanket] and play with herself the whole way.... I wish we could have gone with them. Amy was so hot when we got home, she attacked me as soon as we pulled into the garage. We didn't even make it to the bedroom... fucking instead right in the kitchen. As we went at it, she confessed how turned on she was by the entire weekend and that next time, she wants to be the slave. I'm hard just thinking about it ...
