fuuuuck that's a good one. gotta think about it
1: all the way through
2: extreme penetration
3: size difference
4: deepthroat asphyxiation
5: musk/sweat
6: hyper
7: unretracted foreskins and foreskin play
8: group sex/multi penetration
9: big fat scaly trans butches (more of an attraction but i gotta express it somewhere)
10: oral fixation/mawplay
11: stretchy and/or transparent clothing (condoms included)
12: cum overflow and cum out nose (whether from oral or cum through)
13: casual/public, including accidental sex
14: kindness, overwhelming enjoyment, good moods, care, praise/compliments/apologies
15: saunas, springs, onsens, and wet/sweaty/steamy/slimy places in general
16: fupa/belly play
17: consenting roughness (not like spanking/slapping but like super fast/hard/intense sex)
18: bulges (clothes bulges, body bulges from penetration, etc.)
19: role reversal, subby tops (like me!), changing disposition throughout a scene
20: alien anatomy
i also like when a scene has humour, especially slapstick
