0:00 You've sure been putting in the work to train your muscles recently!
0:02 And you're rock hard, haven't you gotten huge?
0:05 It's nothing! But I can't lose to you and the others, Anzai-senpai!
0:09 Hahaha! How admirable.
0:12 I won't let a younger guy surpass me that easily. I'm not gonna lose face!
0:18 Heh... Well... that's because of the special protein shakes I drink during prime time, isn't it?!
0:21 Huh, "special"!? What is it!?
0:24 It's sperm. Sperm.
0:27 Sperm is rich in zinc and protein, and more effective than a regular protein shake!
0:31 Huuuh!? Seriously!?
0:34 Yeah, isn't a trained firefighter's semen juice amazing?
0:40 Since we do dangerous work side by side, our instinct to procreate and sex drive is heightened.
0:47 So we make thicker, manlier-smelling, guaranteed muscle-building sperm!
0:54 Satou gets a daily dose of my semen juice too, wouldn't you like to be that muscular?
1:00 What a nice response! Alright, shall I put it in...?
1:02 Ngh!
1:04 Guh...
1:09 1:13 Ngh... Kimura, I'm going to go faster...
1:20 Oh❤ Oh❤ Amazing❤ As expected, a new one is the best❤
1:20 Hey, are you mad at me!? We're doing a full body exercise!!
1:40 Alright! Gahh... Ungh!!
1:47 ...Hey Hirotaka, don't hold your moans in.
1:51 ...Huh?
1:54 Ohh! ❤
1:56 It doesn't seem to want to let my huge thing go... Ungh...
2:01 Whether your intestines like it or not, they're sucking me in...❤
2:05 Ahh, it feels so good! ❤
2:16 Oh no... He said this was for the protein, so why does it feel so good...
