>cock
boy/manhood, length, girth, organ, leviathan, piece. Weapon analogies like cannon, spear, shaft, or even "weapon" itself.
>extra dick stuff
Hip-splitting. Displaces other organs. Pulses, jumps, adorably smooth or misshapen and nasty, a cute or ugly thing. Head peeks out the foreskin, shining in its own pre — big as a little finger, thumb, wrist, arm, leg. A third thigh. Each throb punches at [x], it sprews pre as though it could be cumming it, throwing the stuff with every little spurt of genital spittle.
>cum
Sludge. Baby batter. Dough, to make a bun in your oven. Liquid love. Sexual fluid. Genes. Cream filling.
>Extra cum stuff
Kicking and screaming orgasm. Dribbling, seeping, spreading, flowing, viscous and slick, off-white, eggshell, curdled or churned, comfortingly warm. GOO~PYY!!
>Fucking
Rutting, pushing into her core, making like rabbits, dogs, or horses. Breeding. Giving in, collapsing into each other. Mashing bits, sawing away at something, masturbating using each other. Hecking
>Tits / Ass
Bust, chest, bum or butt, basics are good here to avoid hypersexualization. Her mass, shapes, fat, washboard, bitty, overflowing or spilling over, sink into. I only play one woman, forgive.
>Lips
Often I end up describing how this feels, looks, or the action itself, rather than using words for lips alone. Mouth is the only other I can think of at the moment, but I supplement that with lots of — swapping saliva, tasting tongue, lapping at one another, drinking spit and pushing for more, violating the mouth, actual oral sex.
I don't do a lot of sexual content and when I do it often has this weirdo Darkest Dungeon or Lovecraft vibe of making the normal or appealing strange and unfamiliar. Forgive.
