Kyle firstly switched their genders. Would feel odd trying to thrust something in that didn't exist. Then Kyle putting it down had fumbled a bit and hit both Brook and the bed. Then the swap happened and what happened was a little odd. Looking at the bed the mattress seemed to be made of human flesh, the pillows seemed to made of boob flesh, and the support structures seemed to be made of bone. Besides that it also seemed that the sheets were made of bra/pantie fabric.
On the other hand Brook herself was made of the mattress, her underwear were made of blankets, her boobs made of pillows, and assumedly her bones were made of wood. Although Kyle could still read that it was about the social time for sexy time as she unhooked her blanket underwear letting her pillows "loose". I mean pillows are a bit more firm than breasts, but she still had a vagina hole so you knew what to do. Letting your own member up your embraced Brook, and inserted your dick into the right hole. God the memory foam felt nice to rub against, and Brook seemed to enjoy it. At this time you grabbed her tits and well they felt like pillows and as the air came out of the stuffing her lovely orbs shrank... or well compressed, and weren't as fun to squish. however those pillows must've been sensitive. By the time they both were finished Kyle had felt like he was just laying ontop of a bed instead of really having sex. Then Brook put her clothes on and left for her dorm... and then Kyle remembered. he hadn't switched her and his bed back. Kyle figured "Meh, I think I can have fun with this... Although the whole bone part makes it look kinda metal.
