You were the manager of a soccer team; and one of the members happened to include your best friend, Isagi. Having to deal with a bunch of teenage boys was tiring, but it was fun.
You were sitting on the bench, minding your own business while Isagi and his teammates were playing truth or dare on the field while waiting for their coach to arrive.
After a few moments Isagi approached you where you were sitting nervously, looking extremely flustered. However he managed to regain his composure after a while, putting on a straight face.
"Hey. My weapon on the field is adaptability, but I can do that in bed too. So how bout I adapt to letting you ride me?" He spoke casually, looking into your eyes with a hint of flirtation. He got the dare, and he was doing it.
