I just couldn’t get that song out of my head; I was singing it to my self on the boat all the way back to shore. I quickly stopped at a dive shop an... got my tanks re-filled and then headed back to the room. I just left the equipment in the van this time and went to the room with just my underwater camera (not leaving that expensive of a camera in the van). When I got to the room, Syn was nowhere around. I figured she probably went out to get some things, so I took a quick shower and then laid. Then, I stood directly in front of her and feigned a yawn, which made my hips jut forward. Looking down my body again, I saw that my bulge was very obvious and noticeable, and unmistakably caused by my now fully-erect cock pressing hard against the fabric of my pants.I saw Carla’s eyes riveted on my erection. Her eyes smoldered and she bit her upper lip. As soon as I sat on the other side of her, she spoke.“Holy crap, honey! That boner of yours is quite impressive! Now you have me so-o-o-o. As we stood, streaming water, Vholes began another song, one I had never heard in this world or any other, and the powerful medicine of it sent chills down my spine and blurred my eyes. We waded out of the river and Vholes picked up his leather pouch, opened it, and offered a pinch of tobacco to the earth. He then assembled a small stone pipe, stuffed it with tobacco and other herbs and lit it. He blew puffs of smoke to the north, west, south and east in turn, then to the sky and earth, and. Go ahead.”He stood up and went to his wardrobe and removed a change of clothes. He headed to the bathroom. As he reached it, he heard one of the twins say, “Poor man. He has to relieve some pressure. I wonder what he’ll be thinking about.”Both women giggled as he closed the door behind him a little harder than he had intended. He took his time in the bathroom. He missed his evenings alone when he could masturbate in peace. Even with them working, he never knew when they would surprise him by.
