Just how I love getting fucked an anonymous man coming in with a hard cock fucking me and doing his business breeding me and walking away. I never know who just fucked my ass just the way I love it all that warm cum swimming inside of my ass making room for the next one to come in and fuck I don't care if you're straight bisexual or gay as long as you fuck my gay pussy and leave me full of seed
Love breedings like that. Don’t go for it usually but had some anon face down ass up fucks happen and they had huge dicks. Totally huge loads to boot, definitely has an appeal.
Either the top used the pen to update a "load count" that the bottom kept as hash marks on his ass, or he used the pen to mark the bottom's asshole as a fuckhole with arrows and/or a bullseye showing where to insert dick, dump load.
