If she lets Yuta touch them, maybe he won't have those thoughts anymore, and can focus on studying! At first Yuta definitely refused, but after being touched, the incredibly soft, elastic feeling coming from Ayumi's breasts made the student unable to control himself. You want to go further! He wanted to see these breasts, suck them, massage them, fuck her breasts and fuck her pussy! And because she wanted Yuta to be able to focus on studying, Ayumi had to indulge him. And from there, the two fucked from school to Ayumi's house. Ayumi also set a condition: no matter how much he fucked her, he had to study as much as he could...
