In order of preferences:
Highly contrast couple
petite young girl with large/fat ugly old man or black/dark skinned male, milf with young man, etc. greater contrast is better, don't know why . . . as long not female dominant
Lots of Creampie, especially with Impregnation,
Pussy bukkake (ex. Queen8/tokyo hot series), cum injection, stuff vagina with much cum as possible
NTR, but only if consent
GF/wife swapping, let GF/wife fucked another man
Costume
standard blue-white sailor-fuku, school swimsuit, and kemonomimi: bunny girl, cat girl, wolf girl (ex. Horo), you name it . . .as long is not leather/latex and not furry
doggystyle, deepthroat/mouth fucking (not rough), rimjob, bukkake, cum swallowing (gokkun)
dildocam, pussy open wide with speculum
if they made it in one DVD, I'll be very blessed
