It was only 10 minutes into volleyball practice and Haruka was already getting tired. Every serve, pass, or jump literally knocked the breath out of her. Sweating profusely, she crouched down to pick up the ball for another serve.

Haruka was dangerously top-heavy to play volleyball, but it was a sport she deeply loved. Being the only girl with breasts larger than her head singled her out from all other students. It wasn’t her fault though, she was dealt a stellar hand when it came to genetics.

So much so, it took a heavy toll on Haruka’s favorite past-time. The bigger her breasts grew, the harder it was on her poor body when playing. When Haruka first started, she was already decently huge. But, like a switch stuck in the “on” position, Haruka’s body continued to swell beyond comprehension!

First, Haruka’s balance became off. Then, she couldn’t dash effectively. Now, at 125cm, she can’t even spike the ball and struggles to serve with her boobs constantly in the way. And that’s not including all the additional struggles faced outside the gym!

Haruka’s chest-size emphasized while crouching. Her massive mammaries squished against her toned thighs in an unintentional lewd display. “Shit, these things are always in the way…” she bemoaned under her breath.

The scuttle of sneakers was silenced by a deafening whistle. “Haruka! Take 15!” Haruka quickly turned to look at coach. “N-No, I can still play. Lemme do the next serve.” Haruka’s coach sighed, seeing the winded voluptuous student. “Take the bench, I don’t want you passing out…” said coach, with a more gentle tone.

Haruka, with a pained expression, ended up giving the volleyball to another teammate. Haruka shamefully walked past her coach toward the back bench. She plopped down, causing her massive tits to seductively jiggle. Haruka looked down in distress, seeing her intimidatingly expansive breasts lie in her lap.

”You two are gonna force me to quit volleyball…” Haruka said, almost choking up with lamentations as she poked her massive mounds with a single finger. Haruka’s sports bra groaned as her skin felt hot and tender underneath. “Not again…” Haruka protectively hugged herself alone at the bench, feeling her breasts growing against her cradling hug…
