Every day discovering new things about his partner.
This was probably one of the things Mycroft enjoyed most about his relationship with Greg.
He had recently discovered that Greg had a slight fixation on his mouth.
Since Mycroft was not a saint, he had stored the information in a corner of his head for later.
Later being tonight as they ate their dessert in the kitchen.
Mycroft was taking great pleasure in ostensibly tasting each spoonful of his creme brulee. Licking each time the spoon much more slowly and longer than necessary while staring at Greg.
Now he could see Greg's gaze intermittently glide over his lips before quickly looking away.
Of course, Mycroft continued, seeing Greg's cheeks turn slightly pink, his eyes clouded with desire and his breath quickening as he continued.
He looked into his eyes, innocently licking a small bit of creme brulee that had remained at the corners of his lips and raised a candid eyebrow at Greg, " Is something wrong Gregory?"
Greg, his voice hoarse with wanting, replied, "Don't look at me like that. With that deceptively innocent look on your face when you know exactly what you're doing."
Mycroft retorted, licking his spoon in a perfectly indecent manner, "And you, if you don't stop looking at my lips without doing anything, I'm going to take you right here on this counter."
Greg's eyes widened and then slowly took on a mischievous gleam.
He crossed his arms, continued to stare at Mycroft's lips, but did nothing.
Mycroft kept his word.
Because Mycroft always kept his promises.
