All of these should be sweet and gentle
Magilou (Tales of Berseria) getting vaginal while her small breasts are getting cupped, her smiling mischieviously.
Haru (Persona 5) smiling sweetly as she gently gives a handjob, little bit of cum on her body, to imply she's done it a few times already
Lyn (Fire Emblem) riding someone on top, her boobs bouncing gently
Tamamo (Fate) giving paizuri while hugging the person tightly, smiling.
