Mom-Daughter Massage Swap: Part 1

Mercedes Carrera and Moka Mora visit a massage parlor after a day spent shopping. Unexpectedly, Mercedes' spouse, Domenic Kane, and Moka's lover, Lucas Frost, have organized a surprise for them without informing the girls in advance. A guide welcomes them and gives transparent directions on what to do next.
The girls are required to proceed to their allocated rooms, take off all their clothes, and lay down. Following the instructions, Moka goes to her room and reclines near the door on the opposite side. An oblivious Domenic enters the room, not realizing that it is his stepdaughter lying on the massage table.
Lucas admires her physique, even stooping down to observe her intimate area. He lubricates his hands and starts pressuring her lower limbs, progressing towards her thighs and eventually lifting the towel to massage her buttocks meticulously without missing any spot. When he initiates playing with Moka's private parts, she lets out an almost imperceptible sound.
Though she approves initially, she eventually stands up, expressing her discomfort at the inappropriate behavior and implores him to stop. Upon realizing it was not her boyfriend but instead Domenic standing there, she is astonished. The perplexity is mutual, leaving both Domenic and Moka taken aback with the situation - he did not foresee coming across his stepdaughter on the massage table in that moment.
Feeling unnerved, Moka remarks on the complexity of the situation, highlighting their recently linked familial ties, warranting the discomfort she experiences. Yet, Domenic suspects she was enjoying herself under the guise of objection, fueling his belief that she was merely playing tough. To gauge her interest, Domenic proposes continuing the session, to which Moka secretly concurs.
