Sure, here's what I wrote:
To get these, the night before you need to return to the dorm and catch Marco jerking off, or you need to turn down his proposition after returning from the party together. Either way, ask him to jerk off in the bathroom.
The next morning, send him a friendly text to unlock the first two towards the end of the update. Repeat the above, but send a sexual text instead. The third will unlock in the same place as the other two.
