Colin was caught off-guard. Was he actually attracted to boys? Did that mean he no longer liked girls? He looked down at Monica's body. He could remember the excitement he had felt looking at and caressing it just then, but this time when he was down looking at it, it had less appeal. His mind wandered to the impracticability of heaving these boobs around. It seemed to be the case he wasn't much attracted to the female body. Colin was slightly annoyed. He'd enjoyed it so, playing around with Monica's body from its perspective, but the joy of exploration was gone.
Colin's introspection was interrupted by a hand grabbing his ass. Monica in his old body was standing behind with a hand softly squeezing an ass cheek. Colin was unsure how to react. Another hand reached out and grabbed his boob. Colin remarked how pleasant the hands felt upon his skin. They were so warm and strong. Part of him wanted to protest, but he was getting swept away.
"Are you okay with this?" Monica breathed into his ear.
"Do your worst." Colin answered with a shivering voice.
Monica continued groping, but with a higher intensity. His shirt was pulled off, leaving his breasts bare. Colin felt hands rubbing all over the body. A hand moved across his thigh, while another hand softly pinched a nipple. It felt so good. He had previously felt this body up on his own, but having another person touch and caress it was a whole another sensual experience. Every contact was more exciting than he last.
Monica lightly pushed Colin forward. With how top heavy Colin was, it didn't take much force for him to topple over. He landed with his hand and knees on the floor. Monica slid Colin's panties off, leaving him completely exposed. Colin stood on all fours on the floor, presenting his plump ass to Monica. His crotch tingled, a desire to get filled was irresistible.
Colin awaited Monica's next action in anticipation, and then it happened. Monica's masculinity entered. Colin let out a gasp. It felt like Monica pulsated through the entire body. A satisfying feeling of fullness took over. The boobs drooping down down, almost brushing the floor, swung back and forth as Monica rhythmically thrust. Colin loudly moaned at every movement. The speed increased and Colin's mind became muddled in pleasure.
The excitement was accumulating to its big finale. Colin felt a bliss unlike anything before. The sensation completely enveloped everything. He let out an intense high-pitched scream of pleasure. Complete euphoria shook through every fiber of Colin's being. The high intensity peak lasted several more seconds before it slowly waned. Colin heavily breathed and gasped for air. Just as he had collected his air, a similar impulse swept through, and once again Colin was taken over by intensity. The wave of pleasure swept again, creating more convulsions and high-pitched noise. It didn't stop.
