GDHH-197 - Big-breasted stepmom's bold offer: 'I'll be your practice partner, go ahead and do it'

The cast includes Naoko Akase, Iroha Maeda, Sumire Seto, and Nana Miyoshi. They’ve all been active in 'virgin' themed works, right? Was the hesitation because it was their first time together, or is the 'realism' supposed to be them going easy on a virgin? I hate to say it, but since this is an AV fantasy, I wanted to see something more intense—like him being so obsessed with his stepmother he can't function, or pushing her until she's completely exhausted.
