So we both slowly moved down to the bathroom of the train.As soon as the door closed I took out her t-shirt and started playing with her boobs which w...re still inside the beautiful black bra. She opened my boxer and started stroking my cock. I was kissing her on lips and she was moaning badly. I was also moaning as she was caressing my big hard cock. I removed her bra strap and revealed those pink nipple tities. Such huge lovely white tities in front of my eyes. I was glorified to see those. I looked around for Zuri, spotting her hidden under a ridge five meters beneath the surface, her dark body rippled with wave-shadow in the light from above.As I swam to her, Zuri lifted her hands to show me the smooth rocks she held as ballast. A quick search found two more, allowing us to stand in front of each other.The current’s strength forced us to lean heavily into the flow to keep our feet on the smooth stone of the riverbed. Above us the world wavered, our mother and the rock outcrop. She then moved over to the bed and sat down still looking at me and twitched her finger in that come hither way. I couldn't resist it I walk forward slowly and came up to her the bed seemed to be unusually low but perfect hight for what she planed. She reached for ward and unzipped my fly. And unbuttoned my jeans. Slowly she slid them down leaving a tent where my cock pressed against the loose boxers I was wearing. She pulled the boxers away from my growing shaft and pulled them down as well.. "That's kind of scary to think about anyway. But I like touching you, and I like having you touch me." She wiggled against him some more."Have you ever had an orgasm?" asked Bob, softly."I don't think so," she said, her eyes clear. "I never did anything until I met you." Would you like to try that?" Can we do that here?" she asked. "I really like this."Bob looked around. There were people at the bar, and four people swimming in the pool. Others were walking, going here, or there. None were.
