another idea

Bon, Yukio and Izumo stood outside Rin's room. Originally they had gone there to study with Rin and Shiemi and get some help from Yukio but the sounds from the room made them hesitate before entering the room

"ow, that hurts Rin" it was Shiemi

"oh, sorry...here?" he asked

"bit higher...yeah there, thats better" she moaned a little

Bon spoke first "you dont think they're...?"

Yukio shook his head "no, they've been expecting us"

Izumo blushed "i didn't think Shiemi was that kinda girl"

"ah that feels good, bit harder" she let out another moan

Bon sighed "should we come back later?"

Izumo shrugged "i guess, i mean me and you could go back to my room"

Bon took a step back "what?"

"i meant to study" she exclaimed

Shiemi moaned again "this feels great"

Yukio unfolded his arms "as a teacher i cant let this happen" He opened the door "just what do you think...oh"

they looked into the room, Shiemi was laying on her stomach on the floor while rin was kneeling beside her with bith hands resting on her shoulders

Shiemi smiled "i remembered you told me that rin gave good massages yuki"

the rest of the study group was slightly awkward
