The mother

The door opens before Marty can answer and in walks the businesswoman holding a sliver platter full of cheeses and meats. She only pauses momentarily in her stride when she sees her son and the woman she had bought for him at auction in bed, before she walks over to the bed and sets the platter down on the bedside table.

"Hey honey, brought you something to eat and maybe set the mood, but I see you've gone ahead and opened your present. Did you enjoy it?" the businesswoman asks.

Marty's face is red with embarrassment while Charmane is covering her breasts with 1 arm while holding down her skirt. Her hair is partially covering her face and she looks away from the businesswoman.

"Mom!" Marty whines like a teenager. "I like the present, okay?! Geez!"

The businesswoman chuckles, ignoring his attitude towards her and seems more satisfied that he's obviously enjoying her gift.

"Okay, you have a great birthday," she says, then she leaves. Funnily, the moment the door closes, Marty reaches for a piece of salami on the platter and stuffs it into his mouth. With that interesting event over, you activate your teleportation ring and leave, having witnessed enough of this strange rich family.
