It's a bottom's obligation to clean off the tops cock....hell what would happen if the top goes home to his wife, or hubby, and has another guys ass smell on his cock? I always clean the tops cock off, and love it when it's still dripping with cum. And any bottom who cleans mine off after I take him, makes me feel like he has enjoyed the ride, and is thanking me for it. I did recently have a friend get fucked by my hubby, and then I ate my hubbies load out of his ass, before fucking him myself. Why waste any load.
