As she moved under Steve's strong body, Sofia gave up her struggle and just enjoyed the pleasure silently. In particular, when she learned that Vivien was hiding behind the door and peeping, she suddenly felt a kind of inexplicable excitement. This made her cooperate with Steve and moan even louder.
"Ahhhhh ahhhhhh... Ummmmm... Dear... You're amazing... Go faster... Uhh... I want you to go deeper..." Sofia grabbed Steve's head and buried it in between her breasts.
Sofia was sitting on Steve's pen*s, constantly raising her waist and legs, moving them up and down. Steve was sitting in a chair, hugging Sofia's waist and constantly penetrating her.
Knowing Vivian was watching closeby, Sofia deliberately chose several sexual postures that would allow Vivien to see them more clearly. Vivien was completely stunned. She had never seen anyone have sex, not even in the movies!
