The third and last rule ist that we will do this for exactly one hour, no more and no less.When I tell these rules to my sister, she readily agrees. I...��m not sure why, it’s not like I asked her ... aaaaaand there’s the one-eyebrow-thing again. Well, we will see who has the last laugh!I double check that Anna is securely fastened to the chair, then I switch on the butterfly. Judging by her sudden rigid posture, it must be quite intense. And then I up the game by lighting four candles and holding. “This is quite the nice setup you got,” Clint said. He massaged me. Teased me. He had a hungry look in his eyes. “I like it. Things are going great.”“Uh-huh,” I groaned. He teased me. Twisted my nipples. My pussy clenched. Juices trickled down my veins. My robe caressed my rump.He leaned down and engulfed my nipple. I gasped and clenched my fists as he sucked on my nipple. His lips sealed around my nub. Pleasure shot through me. His tongue caressed around my areola. He played with me, his hands. It was so hot we were both butt naked. Teagan knew you were coming so she made me wear something.”WTF! Both of them were naked doing yoga?! - I obviously didn’t say that out loud.After leaving me speechless for a couple of seconds, Sarah laughed and added, “Well, I guess it was for the best. Watching her naked body do all those stretches was too distracting. She has a beautiful body and you’re very lucky to be able to tap that… regularly.” She ended with a wink, hinting that she knew we were. “Oh that feels nice, don’t stop.” Checking that there was no-one else around, I crept forwards and, as I got to the top of a slight rise in the ground I found out the source of the sounds. A woman was laying on a blanket with two men, one had her skirt up around her waist and was stroking her pussy through her panties, while the other had her blouse and bra off and was playing with her tits.I quickly retraced my steps and fetched my wife. I didn’t tell her what I’d seen but as we neared the top.
