Here's what I've found so far in 0.26:
Mom: Jerk off to her while she is suntaning on the pool, Motel Manager will catch you both in the action. (Looks like this is an old event from previous updates, haven't found anything new for her)
Aunt: You can suntan with her on the pool when your mother is not around, no sexual content on this event.
Motel Manager: Visit your second room and you can fuck her without condom when the event happens. Don't know if there's more.
Lawyer: Visit her at 21+ hours and bring some drinks, you'll get the option to sleep on her place and after repeating a few times you can join her in the bedroom and fuck her.
Stepmom: Be on the hall on her house at 22+ hours and she'll ask you to join her, after a few repeats she undresses and sucks your peepee.
Principal + Teacher: Request the principal to grab you from class again (if you asked her to stop), tell her to go to the desk and fuck her bareback, the teacher will catch both of you and join on the fun. After that you can join the principal and get the option to call the Teacher, which unlocks another scene where you go down south on the Principal.
Neighbor Mom: Help her with gardening a few times and she'll ask to wash your clothes, you undress and she witness your mast in full glory. Visit her house at 13:00 (only worked on weekends for me) and look for her, there's a chance you'll get the option to peek on her while she's on the bathroom.
