And a coupleweeks after swim practice started, Jeff was ready to put hisplan in action. Mike had worn light blue boxers and Jeff wasready for the swi...ch. Unbeknownst to Mike, when he dressedafter practice that day, he was wearing Jeff's shorts. That night Jeff mercilessly jacked off in Mike's boxers.Stroking himself right through the cotton fabric, feeling hisdick rubbing against the same places that Mike's cock wouldhave been. The feeling got him so horny that he shot off inthose boxers. Crouching low, David was grateful for the British mania for blackouts. He edged his way to where Julia and Liz were huddled. "You OK?" he whispered.In the gloom he could see that Julia held a small gun at the ready. "We're fine" she hissed. "But we need to get Liz back to her cabin, this open carriage is too vulnerable."David understood what she meant. One grenade through the window and it would be mincemeat for dinner! They began to edge their way back down the carriage. Julia taking point and. Then her hips began to move slightly upwards, once then twice, and then I got the message.I tried pushing more of my dick into her cunt but there was no more to go in. I drew away from her body only to find her hands pulling me back into her again. I was a slow learner, we both were, but after a minute or two I was sawing in and out of my sister’s moist pussy as her hips continued to meet each of my thrusts. Meanwhile a more experienced Phil approached the side of the bed and began kissing. All I could think about was making her happy, showing my gratitude. Kissing down her neck, I decided to do something I've always wanted to. I moved down on the bed until my head was level with her hips and I gentles parted her legs a little more.Face to face with a pussy for the first time in my life, instinct took over. I have an abnormally short tongue but I can move it damn fast, so I put it to work at her entrance. I didn't really know what I was doing, only that I loved the taste of her.
