Reply: "Smoke breaks" with my roommate's girlfriend were actually "blowjob breaks"

It was the night after I fingered my roommate's girlfriend when we were all drunk and he was passed out. I spent the day really horny with memories, flushed about what I should do next.
The following day I didn't see her till the evening. I saw them both in the hall and I was about to go to the roof for a smoke. I smoked- and my roommate did not, and obviously none of us were allowed to smoke indoors, but thankfully we had roof access.
It was then that she went "Hey wait, I will join you." I asked if she smoked and she said only when she can bum a cigarette- she never buys a pack for herself.
The two of us went to the terrace, and my heart raced since I was alone with her. I didn't know how to proceed, so I handed her a cigarette and lit for both of ours.
We were silent for a bit while we smoked. It was dark except for the city lights, and I saw her lean back on the railing. She wore a top- slightly cropped on her waist so that she had just a small amount of her waist showing.
I took a chance and put my hand on her waist, proceeding to her stomach, coming closer to her breasts. She said nothing- just a slight smirk while she kept smoking.
I proceeded to run my hands inside her top, reaching for her tits. I realised she wasn't wearing a bra. I proceeded to slowly touch her boobs and play with her nipples.
She started to slowly bite her lips while she kept smoking, while I felt her tits.
She eventually finished her cigarette and I asked her if she wanted to have another one. She said she didn't but I should go ahead and light one, and she would "keep me company".
I lit another one and she said about how she was really trying to quit smoking, and she should "keep her mouth otherwise occupied" and giggled, and she reached for the hem of my pants.
Given how horny I had been the entire day, I ran my hand through her head while she kneeled down in front of me, and dropped my pants and boxers to my knees.
My cock twitched hard almost instantly and in a very sexy and playful way, she began to suck it. I got a sloppy and wet blowjob while I kept smoking my cigarette, looking at her as she got wilder and wilder while sucking it.
I barely lasted the length of a full cigarette, while she enthusiastically moved her mouth on the length of my hard cock. I said I was about to cum, and she drove her head even harder. I came in her mouth, and she smiled and spit it out beside her.
Cigarette breaks became quite a common thing after that. The next break she wore a skirt, and dropped her panties and made me eat her out and finger her while she smoked. Eventually a few times when we were really horny and it was really late at night, we did a lot more.
