Mamasan told me Summer only offers half service.
Lots of other girls there offer full. You have your choices-Bella, Mimi, Wendy, Amy, and Hanna all offer fs.
Mika, Summer, Coco, Jessica, Elsa, and Kelly are half service but was also told ymmv!
Monica, Tiffany, and Sakura I don’t know, wasn’t told.
Why not choose a full service girl rather than pushing Summer to do it? Again could be ymmv and see her a few times you never know what could happen!
