Can't find a tease

[kurisu]

So i played a certain tease a week ago.

What i recall from it:
- It had lot's of dialogue
- You meet a girl (black haired?) girl on a bridge(?) (there is also a picture where she walks up stairs) and she convinces you to masturbate in public. You made some agreement with her about orgasms.
- You then meet your crush and she tells you she is into you which is inconvenient due to the agreement with the other girl.
- The other girl comes to your apartment where she is fine/delighted my crush is hitting back on me. Later she sits on a sofa and strips.

Can you help me find it?
