A MUSCULAR GUY AND A TINY GIRL'S SEX ORDEALS Chapter 1

"Tell me right away if it hurts." He's my gym trainer, Gaku. There's pretty much a 1'8" height difference between us. We've been trying really hard for the past six months to try to make his huge penis fit inside me, but we've yet to succeed... His thick finger prepare me really gently, but when the time comes to actually put it in, it hurts so much it doesn't work out! When I asked a friend for advice about it, she said I should train my vagina!! Physical training with a sextoy is both arousing and nervewracking. It feels like it might just pop out... if I contract my abs a bit too much...!? And to top it off, I just happened to overhear Gaku chatting with one of his colleagues, and I might be getting in the way of his career, too...!?
