I've kept your expressions and names intact, preserved the word count (it increased slightly due to polishing for clarity), fixed spelling and grammar errors, and made it smoother and clearer for a general audience to read:
Finishing with Valera, using a blowjob to clean up my stained cock, I went up to my apartment, changed my clothes, grabbed my car keys, and went down to the garage.
Just like Sade had promised, my BMW had been returned, the keys inside it. But rather than drive the German machine, I entered my Camaro.
Having spent much of the day wetting my dick and curing my hunger, I should have been in my apartment bent over my books, but I didn't want to miss the opportunity before me.
Not only was I going to squeeze a massive ass, but I was also going to suck on magnificent titties and receive the best blowjob a human could get.
Reading was important, but I could shore up a bit tomorrow morning. Best of all, there was Sade, who would be within 100 meters of me.
