Colin saw Monica quickly type something into a field. He couldn't get a proper look of what kind of change she was making. He tried to lean closer to get a proper look. While he was leaning forward, his field of vision changed and suddenly he was really close to the computer screen. He leaned back away from the computer screen and as he did, he noticed his movements felt off. He looked down at his body. His view was obstructed by Monica's ample chest. He realized what had happened. He had turned into Monica. What about Monica? He turned around and there he saw himself. Monica must be in his body.
"Neat isn't it!" Monica exclaimed from Colin's body.
Colin tried to answer, but hearing Monica's voice coming out of his own mouth caught him off guard. He paused for a bit, collecting himself, before he tried speaking again.
"Yeah. It's quite different. That's for sure." he spoke in Monica's soft higher-pitched voice.
Colin couldn't help but noticing different new sensations. He felt the roof of his mouth having a different texture. He felt the material of his shirt brushing over his boobs. He felt his hips hips spilling over the surface of the chair. He felt a wet void between his legs. This body was so sensitive unlike his normal body. He reached his hand under his shirt, disregarding the real Monica being right in front of him. He touched one of his nipples. It was so responsive. He shivered from the sensation. He kept playing with his nipple. He unwillingly let out a feminine moan, causing him to stop.
"Enjoying ourselves are we? After being all over my body last night I thought you would enjoy being in it. There is just one more thing I have to swap to finish our change, so can you move a bit please?" Monica requested.
Colin complied and stood up from the chair. He felt his entire body jiggle a bit as he moved. He wondered what Monica was about to change. He looked at Monica typing away, awaiting a sudden change like last time. Then, Monica stopped typing. Was another swap made? Colin couldn't tell. He looked at Monica to see if anything were different about her. She was still in Colin's body, but there was something about it. He couldn't stop staring. He tried to figure it out. He noted the contrast between their two bodies. Monica had his strong defined arms, unlike the soft and weak arms he now possessed. Colin gulped. He imagined those arms fondling his body, the fingers digging into his flesh. Continuing to look at his old body, Monica stared back at Colin with lust in the eyes. Colin realized what Monica had swapped. Their attractions and sexuality have been switched.
