My Roommatecoworker Wants Me to Fuck Him to Cover My Shift

I've been living with my coworker for quite a while now, and since he's been at our job longer he gets every weekend off. Meanwhile I am stuck working 6 days a week with only a day off during the middle of the week. I had a guy ask me out on a date this coming Saturday, and, well. It's been quite a while since I've gone out with anyone, so I really want it to happen. So, of course, I go to ask my roommate. I knew he was always a skeeze and kind of an asshole, but didn't think he'd go straight to wanting me to fuck him in order to do a simple favor for me. Not only does he want to fuck me, but adds in a blowjob too once I agree. It turns out fucking him wasn't so bad, but I had to hide that I was enjoying it the best I could. So I told him to hurry repeatedly, and asked him MULTIPLE TIMES, to not cum in me. What does he do? Cums in me. What an asshole!
