SW-450: Doedd gen i ddim perthynas gyda merched, ond fe wnaeth gwraig fy mrawd Mr / Ms fy nhemtio i fel na fyddai fy nheulu yn darganfod, felly roedd fy Ji Po dibrofiad ar fin ffrwydro. A wnewch chi adael i mi ei fewnosod er bod fy mrawd mawr gerllaw ~?

I had no relationship with girls, but my brother's wife Mr./Ms. tempted me so that my family wouldn't find out, so my inexperienced Ji Po was on the verge of exploding. Will you let me insert it even though my big brother is nearby ~?
