OK so I bought the three newest ones
Side Effects: Not so great, again like Dr Enlarge videos where she is unwilling and beign watched on webcam by creepy scientists or something. Too bad because the growth is great. But if you like that motif you will like it.
Magic Ring: AWESOME. Good growth, she revels in it, gets horny, masturbates.
Bust my buttons: Good but not as good as Ring. Button popping not as good as advertised. Still very good, has 2 growths like Magic Ring too.
