Day two, at the water fall. About five miles into the ride, headed for a water fall, Scott told Anne to ride topless since we have not seen anyone out on the trail. She told us if the e out your short come off. Scott and I stopped, stripped off, and said your turn! Anne removed her top, a perky 34b and nipples to die for, proceeded with sucking and wanking the both of us. It was the first time I saw Scott's cock close up and hard. Just five inches and thin. Myself an average six but quite thick. Soon Scott took Anne from behind and I got to fill Anne's mouth once again. I popped my load into her mouth she swallowed most of it. they contined fucking for another ten minutes. Scott pulled out and laid on his back. Anne lowered her neatly trimmed pussy down over him. I watched her lips being parted as his cock was enveloped. A rode him long and hard like I was not even there. I stroked myself to a second erection and A reached out for it. I stepped forward and again she sucked it. Her tougue was circling around the head and one free hand cupped my balls. Next she started to penertrait my ass with a finger all while riding S. Ahhhhhhh i gave her three spurts and then dripped a little on A's tits. Next A lent forward grind her mound into Scott. They both came and A fell on top of him. Soon we all were back on the trail, riding slow, with Anne topless. Headed our way was group of guys they all approved of Annes attire or lack of it. The last one stopped and told us that there was a boy scout troop a few minutes behind them. Anne covered up and we were on our way again.
