Ball Tattoos, inspired by the hentai trope of womb tattoos. Each person can have up to two. Created by Umbrakinetic on FurAffinity.
Counter: Each day, you start with a number of pips; each one prevents you from reaching orgasm but disappears when it does. When all of them are gone, you unload even more cum than you would have unloaded through all those ruined orgasms.
Burning: Your arousal determines your body temperature.
Buildup: Cum is stored in the balls. The longer you wait, the more satisfying (and much more voluminous) your next cumshot is.
Primal: The closer you are to orgasm, the more feral and aggressive your mind becomes. This headspace wears off over time.
Gush: Your precum is now normal cum. Any time you would ooze/spurt pre, it's a more intense and gratifying mini-orgasm.
Restless: No refractory period between orgasms; each one gives you a stamina boost and your pleasure won't hinder your urge to continue.
Streak: Each cumshot makes the next one larger, and the orgasms become more gratifying if it doesn't take overlong to reach. Streak decays with time.
Addiction: Short- and long-term, your cum and precum have addictive effects.
Scent: Your sack emits an aphrodisiac scent so powerful it's difficult for others who smell it to concentrate, even if you're wearing plenty of clothing. Your cum also has this trait.
Tribute: Caresses and licks increase the sensitivity, production, and size of your balls.
Feast: Your cum alone can sustain whoever takes it, and the it tastes good.
Blessing: Depending on receiver's preferences, penetrating them can enlarge their body parts and/or enhance their sensitivity temporarily.
Sense: Your balls are particularly prone to pleasure, even moreso than actually penetrating your partner.
Breed: Your sperm self-fertilize and become eggs that your partner can extrude.
Hyperfocus: Cum production, genital sensitivity, size, and stamina increase as you concentrate on lewd thoughts.
Incubus: Your offspring have their own random tats.
Trance: Any sense (smell, touch, and taste much more strongly than sight/sound) induces a lustful trance in others - they're more susceptible to commands but still may choose to refuse.
Perspire: Your sack is more sensitive to heat or stress and you sweat more.
Elasticize: Your precum and cum can make other creatures stretch to fit you.
Bond: Your pleasure, precum volume, and cum volume are multiplied if you're truly in love with your partner, doubly so if they have the same tattoo.
Slumber: You have lewd dreams, with size and production increased, but you don't orgasm in your sleep.
Echo: Hentai sounds galore! Churning cum, your pulse roaring through your shaft makes audible throbbing. The more pent-up you are, the louder.
Geyser: DRASTICALLY increased precum. Leaks a bit even when not aroused, and constantly when you are.
Inert: No sperm cells, no pregnancy. Breed tattoo overpowers this one.
Dominate: Your size and production scale to your assertiveness and dominance.
Symbiote: People that come in contact with your fluids feel the same sexual sensations as you do. Wears off with time.
Exploit: A particular trigger gets you peak horny, enlarges your genitals and production. Other people can easily figure it out.
Shine: Your precum and cum glow brightly, even visible through thick clothes and skin.
Expel: When your body has produced a certain amount of cum, you blow a huge load even if you weren't previously aroused.
Rakehell: For each different person that brings you to climax, you permanently have more staminal, production, and size. The number of such people is displayed in the tattoo as pips.
Virus: If you're fucking someone with a sack without tattoos, they get this one and your other one (if you have another). Wears off over time.
Bolster: Greatly enhances your other tattoo.
It's springtime! Tag #doluusa or #raense with your dream frontsack/backsack combination, and maybe you'll change her mind!
