Een geheim tepelonderzoek door twee vrouwelijke leraren, Marika Naruse & Izumi Asato

Watch as we observe the study research for woman's body, the changes in Ms, Izumi ASATO's black-dot nipples, gradually increasing in size as Marika gently touches and licks them. Then, Marika delves deeper into the elasticity of nipples through various touches and licks. In the latter part, Izumi shifts her focus to Ms. Marika NARUSE's beautiful pink nipples, pulling and pinching them for a closer examination. See the results they found out!
