It was just a small boat that Jack and Jill had, a small half cabin runabout with an outboard motor. One day they invited Terry and his wife to go with them on a trip in the boat. It was a warm spring day when they headed off to the Myall Lakes. It was just a short cruise up the river to get to the lake at the end. The weather was perfect, very little cloud in the sky and very few other boats around. They seemed to be more interested in fishing that sight seeing. By the time they reached the top lake itself, there were no other boats to be seen anywhere around.

Taking advantage of the situation, both Terry and Jack stripped off to work on their tan and encouraged the girls to do also. Which they did, they all enjoyed the warm rays of the sun on their naked bodies. Cruising around the foreshores they found a small beach with shade trees around. It looked perfect for a picnic spot. They ran the boat close to the beach and put out an anchor to keep the boat safe then waded ashore. The spot was perfect, shaded and private, just in case there were any other boats around, which there were not, as the lake appeared to be deserted. After having morning tea, they spread out blankets to lay upon and enjoyed the suns rays and the quite tranquillity of the lake. The boys, laying out on their backs had not noticed that the warmth of the sun, plus of course, their thoughts as they watched the girls spread a sun protection on their bodies. The sun glinting on naked female breasts and thighs brought their inner thoughts to subjects that were to say the least, were a little naughty.

“Hey Jack”, Terry said. “Do you remember that time we took the girls up the hill at your place?” “Sure ” replied Jack. “What are you thinking? “I am thinking we try it on both girls?” “OK sounds good to me”, said Jack, “but how do we talk the girls into it?” We will start with something small and build up to it.” Terry asked the girls if they really knew their husband's body very well? “Of course we do.” they both said ”Why do you ask?”. “I don’t think that you do” said Terry “and I can prove it!” “How”? asked both girls Easy, just kneel down and put on this blindfold so you can not cheat, then we will stand in front of you and you have to say who it is in front of you. We will not say anything and then change places and you have to guess again as to who it is in front of you. If you get it wrong, you have to do anything we say. Sounds like fun said Janice, and what if we get it right does that mean you have to do what we say you have to do. Sounds fair enough, both boys agreed.

Both girls knelt and put on their blindfold, Jack indicated to Terry to stand in front of Janice and Jack stood in front of Jill. A tap on the shoulder meant ready to start. At first, both girls used their hands to feel the legs in front of them. Janice got a bit more adventurous and slid her hand up the leg to the groin area. Feeling around, she could feel the cock she was touching slowly rise. She thought, “this is simple, its Terry, he always gets worked up when I touch him there.” Meanwhile, Jill was having a good feel around Jack cock and his balls and he very soon was hard. Jill said to herself, “This is Jack he always get worked up this fast”. Jack bent forward so he could pick up a small jar. Inside it was soft chocolate mix he had prepared earlier. He put some onto his thumb and held it close to Jill's mouth and got her to taste it which she did and because she likes chocolate she sucked it off his thumb. Then Jack poked his penis into the jar and covered it with the chocolate and put it close to her mouth. She immediately started to suck the chocolate off his penis. Terry seeing what Jack had done, did the same with Janice.

Jack reached down and using his fingers slowly inserted a finger into her pussy and first one, then two fingers and slowly massaged her and could feel her pushing down onto his hand wanting more. Jill was so worked up that she wanted to take off the blindfold and demand satisfaction, but she remembered the conditions. That would mean that they would lose the challenge, so she just knelt there and enjoyed the sensations.

Another tap on the shoulder meant that they would change over and try another body The boys changed places without saying a word and tapped the girls on the shoulder to show that they had to guess again. This playing around was having an effect on both Jill and Janice, they could feel sexual desire arising in their bodies and making them moist and feeling daring. This time they allowed their hands full reign to explore the body in front of them The boys were also feeling the sexual desire mounting up. Janice leaned forward and put Terry’s penis into her mouth and slowly started to slide it in and out while using her tongue on it.

Terry could not take it and pulled it out and both boys stood back and said, “OK take off the blind folds”. Which the girls did and blinking in the sunlight adjusted to the light again. “Right “said Jack “Which was which?” “That was easy” said Janice, “ Terry was first, then Jack”.

”I am not sure” said Jill “ I got confused I thought it was Jack at first, but then I thought, perhaps Terry, I am confused”. Both boys triumphally said you are both wrong, so you have to do what we want you to do.
