Ai de Asobu.

A collection of short stories by Ninomiya Hikaru featuring various characters and scenarios. One story involves siblings engaging in a suggestive game that escalates to sexual activity. Another follows Sudo-san, who has sex with Takahara-kun after he confesses his feelings, only to face the challenges of a long-distance relationship when he moves away. A third story explores the rumors about Izumi Taeko, a strange and unpredictable girl, suggesting that a coin might be all it takes to get what one wants from her. The anthology includes other brief, standalone tales with differing themes and character interactions.
