The prompt was compulsion.
oOo
Strawberry Temptation
He watched her from across the hall. Laughing and joking with her friends. Her hands gesturing in the air as she told some story or another, everyone as captivated as he was by her charm.
He tried to concentrate on his food but her laugh echoing through the room made him glance in her direction. He was rewarded by the sight of her sinking her teeth into an overripe strawberry; her tongue darting out to lick the juice from her plump lips.
That was enough to push him over the edge.
He left quickly before he acted on his compulsion.
