Ah, they're having sex... it's sex...
It's the first time I see someone doing it...
So lewd... Sensei's voice... The sound of bodies smacking together... her swaying breasts...
I can even smell it...
This is what sex is like... Aah..."Ah... Ah... Sensei...!"
"There's a girl sleeping next to us... so try to be quiet..."
"Sensei... Sensei...!"
"Don't be that greedy... fufu"
"Ah, I'm about to cum... Can I cum?"
"Sure, go ahead"
