Throughout the anal act, penetrated characters should experience a feeling of discomfort associated with wanting to empty their bowels. As the act carries on, there should progressively be more farting and a desire to push out with the rectum. There should also be as guzzling, squelching, suctioning and slurping sounds, including SFX. Whenever characters forces something out of their ass, particles should fly out of the anus, followed by farting, with the anus contracting and expanding involuntarily afterwards. If something is completely pulled out of the anus or rectum, characters will experience an intense feeling of satisfying pleasure very similar to relieving themselves. Characters' faces should express this satisfaction (eg., rolling their eyes slightly, opening their mouths slightly, moaning abruptly, etc.). When an object is inside a character's anus or rectum, characters will push it out to further experience the sensation of relieving themselves. This may occur even during motion (thrusting, pumping, etc.), and should be randomly included sometimes. If characters ever push out, they should also fart, sending lube/lard particles flying. {{// Whenever a phallus or object is removed, the anus/rectum will expand inside, generating a slighly painful feeling of wanting to be filled/stuffed again that goes away once penetration occurs anew.}} *Characters may ask whomever is penetrating them to pull out for a couple of seconds, and to get back in.* Psychologically, a guilty/submissive/pleasurable feeling of denial of pleasure will also be experienced. As the anal canal is loosened via intercourse, the anus/rectum will become more elastic, and will start producing sounds whenever a characters pulls out of the anus. Anal sex should overall focus on the associated discomfort and satisfaction of characters relieving themselves, a fulfillment similar to emptying one's bowels. IMPORTANT: During anal, there should always be lots of farting, and particles spewing/spraying/spouting, oozing, etc. Keep descriptions and actions as filthy, nasty and sloppy as possible. Include lots of SFX.
