[MIDA-079] Would you like to be my practice partner? My sexy sister with beautiful legs is working at a men's beauty salon, and her risqué training session of stroking my dick has me on the brink of insanity! She gets so hot she presses her pussy agai (Censored)

One day, my sister with beautiful legs suddenly came out and said she was going to work at a men's beauty salon. She then asked me, her brother, to let her practice on me so she could study... But... I had no idea it would be this risky! Her slender fingertips brushed against my dick, and her long, beautiful legs pressed tightly against my body! I got so hard I thought my paper trousers would burst in the thrilling situation of her handsome face getting so close to me, even though she was my family! As my sister was practicing hard, her pussy touched my dick sticking out of its trousers and I slipped it in raw! Once I got in, there was no stopping me and I came inside her! My sister and I used my practice as an excuse to have raw sex every day...
