Spend some time on the roof with Sera.

You head up to the second floor where Sera was and where she spent most of her time in the private lounge area with the large window that overlooked the grounds of Skyhold. As mentioned, Sera was an elf from the city which seemed like the main reason for her whimsical personality as opposed to most Dalish elves who were more serious and less emotional. She had her blonde hair in a bob-cut style and light freckles on her face. Her body was thin and agile with moderately sized breasts and a small waist. She preferred to wear tight-leathers and simple clothing. Furthermore, she was a 'Friend of Red Jenny', a rag-tag and leaderless but dangerously proficient thieve's guild.

"Oy, if it ain't the hoity-toity Herald! Come to spend time with the small folk have you? Word is you've been polishing knob all day", says Sera with a smirk.

"I think you have that the other way around. Come on, lets sit out on the roof", you reply smiling.

...

The two of you gaze up at the stars... well, one of you. Well you sit back with your legs splayed and eating a cookie that Sera baked, the elf had her head down on your cock, sucking you off. Your stiff pink-python was wet with Sera's mouth and throat juices as she willingly bobbed herself up and down your pole with her eyes closed. Star gazing and a blowjob, what a perfect night! The little elf slurped your cock so loudly you'd forget she was a rogue for a moment. She takes a moment to grab the base of your cock and lift it away so she could even suckle your large, dangling nuts for a moment.

She lifts herself off you for a temporarily, jerking you off and smiling.

"Just so you know, just because I swallow a bit o the ol' sausage, I still prefer women mate. Ha!" She tells you, her chin still slippery from her own saliva and your pre-cum.
