Mark is a 5'11" guy who lies on his dating profile, saying he's 6-foot. He's a lean built man with black hair who shaves his hair smooth. He prefers to be hairless--groin included. His intimate parts are impressive--his penis is just shy of 7" and even his testicles are slightly bigger than typical.
Eve is a 5'5" girl who will eat food even if it's what she didn't order, to avoid a conflict. She's athletic, but since graduating school she hasn't been nearly as avid as she once was. She has B-cup breasts and a slim figure, though the squats she did in the past at least let her have a butt when she poses right.
Eve and Mark were about a year into their relationship. Well within the romantic and sweet time of learning each other's personalities and blending their lifestyles. Unlike their past relationships, each could really see the other as their partner for life. They just clicked in a way that felt natural, but there was still insecurity and anxiety from the past. They were still in the nervous excitement that comes with testing boundaries and sharing personal thoughts and behaviors, hoping the other wouldn't think you're crazy or gross.
Their sex life was great, each supporting the other and being mostly communicative, though Mark had a kink he was worried about. He'd kept it to himself in past relationships, but this one was different. He was serious about Eve, and loved her enough, that he wanted to take the risk. Besides, she was supportive everywhere else. They both were.
He'd brought up ballbusting to her, trying not to feel embarrassed about it. She at first teased him, of course, but quickly the two got to explaining boundaries and realistically putting this into their bedroom. Eve was really concerned for safety, "But like, how tough are you? Er-, are they?"
"They're like really tough," Mark said.
"No, really," her eyes narrowed.
"Really! They just hurt a lot. But, like, no risk of trauma. Not if we're doing normal stuff--I don't want you to use a sledgehammer."
"Oh God, do people do that!?"
"No! Not like for real. I've seen videos where-"
"Videos?" she arched a brow.
"Shut up," he laughed, "like one video. And it was super fake, guaranteed. The real danger is blood flow if you tie something up."
She grimaced, "Do you... want that?"
Mark's heartbeat sped up. He was worried about judgment, "Kinda. I mean, it's practical--if you put twine around the boys, it keeps them from running from you when you're trying to hit them."
This fact surprised her, "What, are they hard to hit?"
"Well, they're not in the business of being hit, generally."
They talked for a while about his anatomy and his wants. She was curious, but worried. "I'm down to try this, but I'm worried I won't enjoy it like you will. I don't want you to get in your head if I'm hesitant. Besides, I'm not really a 'dom' or anything in our other kinks."
He was relieved, "No worries, I swear I'd love anything you did."
But, life got in the way. Work was picking up, for both of them, and the stress and long hours was detrimental. They'd outlined their plans, boundaries, safe words, etc. But, the activity itself was slowly being forgotten.
The next morning was a weekend they both had off work. This was the big opportunity--for them both. Adulthood sucks.
Mark stepped into his living room to see it'd been cleared to leave a large space. His soft rug, recently cleaned, was in the center to give a wide area for their activities. Eve stood in the middle, hands on her hips, trying to look commanding. She was succeeding.
Mark wasn't used to this, and spoke in his usual flippant way, "Did you sleep on my couch?"
Eve didn't flinch, "Yes." She was mentally screaming to herself, unsure of what she was doing or if it was attractive.
Mark rubbed an eye and joined her, kissing her cheek, "Sleep okay?"
Eve put a gentle, firm hand on his chest and pushed him away. She inhaled deeply to calm herself, and said, "I'm going to hurt you now, so pull down your pants."
Mark's eyes widened, "Oh, that's hot."
He pulled off his pajamas and knelt down in front of her. He was in just his gray boxer-briefs underwear, his soft bulge leaving an imprint on their front. Eve could see the outline of his long cock, even seeing its head outlined in the gray shadow.
She stood in front of him, arms crossed, wearing a soft black shirt and matching shorts that shined in their synthetic fiber. She said, "Pull them out through your front... pocket... slit thing."
Mark reached down and withdrew his genitals, hanging them out of the front of his underwear. The hole made for them naturally was snug enough to hold his dangling balls, so they wouldn't move too much. Eve shook her head, "No, not your dick. Just your balls."
Mark stopped halfway, his eyes widening. He let go of his privates, letting just his dangling orbs swing below him. His dick hardened, pointing upward toward his navel, trapped in-place by the tight cloth. Eve breathed deeply, taking great effort to tear her gaze away from her boyfriend's impressive piece. She looked down at his loose scrotum, wondering if the warmth from his well-rested sleep and comfortable pajamas made him this way every morning. She asked, "Is it better, or worse for them to be loosened up?"
Mark replied, "Oh, way better. Much easier to get to them when the sac is barely holding them."
Eve approached him, "Hm, that's weird-I usually like how they look more when they're all tight."
She crouched down to look at them, her face inches from them. They were shaved hairless, for ease and hygiene. Eve didn't mind the hair, as long as it wasn't fully jungle down there, but Mark preferred it for both of them. They were like a lava lamp-constantly in-motion and adjusting from his breathing and body temperature. She saw his dick twitch, and his balls moved with it. She raised a hand, "I'm going to slap them."
She realized that wasn't really very hot of her to say, though she'd meant for it to sound dominant. She quickly added, "If you make a sound, I'll slap you until you're quiet!"
Her heart was pounding-she had no idea if this performance was doing it for Mark. She looked up at him, and he looked ecstatic. He nodded urgently. She held her hand up, vertically, then adjusted it to be palm-up underneath his balls. Then she hesitated again, and adjusted her hand to be sideways, palm faced to slap both balls in a quick strike. She was shaking now that she was unsure how to hit them. How could she mess this part up?
Mark spoke, "Uh, Eve?"
She looked up at him, and met his puppy-dog gaze. He had a snide grin on his face and lust in his eyes. He said, "What if I'm talking now? Do you think that's begging for punishment?"
Eve smiled, feeling reassured by him. Why was she so in her head? He'd already told her he'd love whatever she did-and he was literally asking for this. She flicked her hand, hard, swiftly between his legs. The sound was a sharp slap that surprised her-she didn't realize it'd sound so loud! She immediately looked at Mark, and saw him biting his lip and closing his eyes tightly. He sighed in a controlled, quiet manner, and breathed in. He opened his eyes and she melted. Or, she would've, if she wasn't in-character.
She felt an instinct to comfort him, hold his balls in her hand and massage them, or kiss her lover and ask if he was okay. But, she saw that he wasn't just putting on a brave face-he was listening to her command! She felt something in her chest, some emotion that was mixed between pride, power, and happiness. It was something like passion.
She said, "Looks like you deserve a little reward."
She removed her sleep top, revealing her pale skin. She grabbed his shoulders and leaned over him, giving him a lovely view of her soft breasts, gently swinging before him. She asked him, "Do you want to just look at them, and rest your hurt balls? Or," she shook her shoulders a bit, bouncing her boobs a foot in front of his face, "do you want to suck on them, and earn a punishment knee to your tender testicles?"
Her vagina was wet, slightly damp, mostly at the situation being so intimate. She'd put on a show like this before, but never had she been the one to force such a move onto Mark. Normally, it was something like a strip tease when Mark had already initiated something. This was freeing and exciting. And, she already knew what he'd do.
Mark latched onto her nipple, pulling it deeply into his mouth and running a greedy tongue over it. She pressed into him, allowing him to drink her in as far as he wanted. She smiled while his warm mouth worked her tit, and he moved onto the other. He flicked his tongue vigorously over the other nipple. Eve chuckled into his ear, "Okay, honey. Time for your dessert."
She slammed a hard knee into his balls, crushing them up under his perineum. He gasped in pain while her foot returned to the ground. She held her chest to his face, thinking it would help to soften the blow if he had a distraction. It also served to partially gag his groans of pain.
He doubled forward and Eve moved out of the way. He grabbed his gonads, laying his head on the rug. Eve rubbed his back gently, then asked, "You okay?"
