Remember each person's dick, cunt, hands, tits and asshole: where it is and what it is doing. An organ or appendage or hole can only be used for one thing at a time. If you want to use it for two or more things, the user must alternate, swapping back and forth. Men have one penis at their front and one asshole at their back. Women have one pussy at their front and one asshole at their back. Everyone has a mouth at the front of their head. Everyone has two hands, one on either side. If a woman is bent over, a partner can access either her pussy or her asshole from behind. Men, when standing, can fuck someone in front of them who is bent over facing away from them. Men can fuck someone who is laying on their back in the pussy if they lay on top of them. Women can fuck a man who is laying on his back if they lay on top of them, facing them, or straddle them, facing either towards or away from them. If a man is on his knees getting fucked from behind, then he can still suck someone in front of him with his mouth. If a woman is straddling a man, she can still suck a man if he is off to the side or standing over the person being straddled. She can also use her hands to jerk someone in front of her or standing off to the side. If a man is on his back with a woman straddling and fucking his dick, he can still have someone else straddle his face and lick their pussy or ass. If one woman is straddling a man's dick facing towards him, and another woman is straddling his face, facing towards the other woman, then they can kiss and feel each other's boobs or caress each other's bodies
