That phone call was definitely good. I love the 'stealth sex' trope that is so common in NTR stories.
My favorite scene was easily the video conference call. I'm hoping for another one like that. The
blowjob at the karaoke was too tame for my tastes.
I keep on imagining a scene where Laura calls Harry and tells him that she took Luca out to dinner to thank him for all his help on the project.
Harry would hear the sounds of the other people in the restaurant in the background and take her words at face value, but, in reality, what he would actually be hearing is a youtube like this one being played over speakers:

Laura and Luca would actually be in Laura's bedroom. This would happend after Laura has completely fallen and become Luca's woman, so she would go on and on to Harry about how much she 'appreciates' Luca, how much he supported her during the project, and that she hopes the three of them can remain close friends. (This would give her an excuse to keep Luca around without raising Harry's suspicions after the two of them get married.)
Luca would then make a comment about how well he and Laura work together. Luara would agree, making Harry a little nervous. Luca would then go even further and say that, if Laura wasn't with Harry, he would have taken her for himself. When Laura laughs and says 'Guess you missed your chance, huh?', Harry would have a minor heart attack as he flashed back to Maya.
As the conversation continues, Harry would then begin to hear things that you would typically assume to be sex (sucking and slurping sounds from Laura giving Luca a blowjob; skin hitting skin as Luca fucks Laura from behind, Luara's occasional barely contained moans, etc.) but the ambient sounds of the '
restaurant' would cause him to doubt himself. Meanwhile, Laura would become more and more vocal. When Harry questions why she sounds so strange, Laura will say it's because the food is so good.
I can see the scene in my mind now:
"Are you okay, Laura?" asks Harry.
"(Mmff!)...Oh, yeah, babe," she replies, barely stifling a moan as Luca slams his cock into her from behind. "This food...(Ugh!)...It's just so...(Ah!)...fucking amazing!"
"Yeah, you like that?" says Luca. "Here! Have some more!" Then he starts fucking her harder and faster as he pushes her face into the bed to muffle her screams.
"(Mmmmmfffffff!!!!)" Laura's pussy clenches around Luca as she has a huge orgasm, causing him to cum inside her after a few more thrusts.
"Laura?" says Harry. "Hey, can you guys hear me?"
"Sorry," says Luca as he sits on the bed next to Laura's unconscious body, "yer fiance just ran off to the bathroom. Maybe the food here ain't so great after all." Then, as he gropes Laura's breasts possessively, he adds, "So, Harry. Given any thought to who your best man is gonna be?..."
