He felt the heat of her body and the softness of her breasts as she gently pressed against him. They were in the bird section of the natural history museum, where they had gone at her suggestion in their lunch break. He again felt the pressure of her body, this time he was sure he could feel the hardness of her nipple against his bare arm. He couldn't believe this contact was accidental. It had been her idea to have lunch together, and he had agreed, but with no thought of sex.
But here they were, she rubbing her breasts suggestively, but so, so gently against him, and he confused, aroused and unsure how to respond. She was his new colleague, and he was in a relationship. He tried to talk about the exhibits, but she displayed no interest in what was around them. Rather, she smiled and stayed close. The museum, in an out of the way section of the university, was deserted apart from themselves and the curator at the other end of the gallery. Along with the hardness of her nipple pressing against his arm, he could feel his own hardness starting to push against his shorts.
They moved further along the aisle into a darker section. As they walked her hand brushed against his. But still there was no explicit acknowledgement of the charged atmosphere between them. She smiling and talking about herself and her job, he wondering how the situation would develop and if she was just flirting outrageously or really wanted sex.
At the insect cabinet she stopped and pointed to a large colourful butterfly on the bottom shelf. He bent to see it more clearly, and felt her hands caress his arse. He stayed still, rigid everywhere. Her hands moved slowly around to the front of his shorts, feeling for his erection. He was unnerved, but had never felt so aroused. He could feel her breath on his neck as she bent forwards and rested herself on his back, pushing herself close, he could feel the pressure of her breasts through his thin shirt. She found the zip of his shorts with one hand, while her other hand gently rubbed him through the material of his shorts.
