You change your shape a bit and slide over James' leg I his speedo. James thinks it's the water moving his speedo, but he quickly grabs his ass when you start to force yourself in. "Ahhhhhh!" James grabs his ass in pain and goes under. He starts to panic and swims to the surface again. Now that his butt is vulnerable again, you quickly force another wave of slime into his tiny ass. Exhausted and gasping for air, James must focus on staying at the surface, giving you the opportunity to shove the rest of you up his ass.
James grabs his ass a final time and goes under again. Right then he starts to lose consciousness and faints. You slowly start to feel your new body as it floats down to the bottom of the pool. As soon as you are in control and realise the situation you're in, you use your new body to launch yourself from the bottom of the pool to the surface with your strong, new swimmers legs. *Gasp* The moment you reach the surface you start gasping for air. You quickly swim over to the side of the pool and hang on it while panting. "Damn... That was close..." you say as you pull your new body out of the pool with ease. You look down at your borrowed Speedos and see the bulge inside it grow.
You dry yourself off and walk into the house. In the hallway you find a mirror and you close your eyes before looking into it. Now standing in front of the mirror, you open your new eyes. Your handsome, strong and young neighbour James looks you right into the eye. You can feel your new member growing, every second you look at your new self. "Wow...." You say in James' voice. "Looking good!" You smile and look down at your dick, which has changed its position and is now sticking out from underneath the speedo. "Heh heh..." You stroke your cock a bit and take off your Speedos to see your new body in all it's grace. "I never knew my neighbour was this hot." you say in his voice.
You look through the widow in the living room and don't see any cars in front of the home. Standing at the stairs you scream "Anyone there?!" But no one replies. "So the house is mine..." You walk up the stairs and, after opening some doors, enter James' room. "So, this is my new room?" "Not bad." You lay yourself down upon the messy bed. You wiggle around a bit to make yourself a little more comfortable. "Hmmm... This is nice." After a couple minutes you get up again and walk to, what looks like, James' wardrobe. You open it and are surprised by what you see. "I knew you liked swimming, but this is a little too much..." The clothing in the wardrobe consists for at least 50 percent out of swimming outfits.
You grab a full size swimsuit and hold it in front of you. You step into the leg openings and pull it up until it has wrapped itself around you tightly. "Wow... How can you ven move in this..." You walk outside to the pool and stand on the edge of it. You look down into the water, noticing the visible bulge in your swimsuit. You look around and give it a good squeeze. "Hmmm..." you softly moan. You jump into the pool feeling all the water soaking you and your new suit. You swim a few labs before going out of the water again.
