My new girlfriend, Seira, has a great personality and is very kind. However, she's shy when it comes to sex, which left me feeling a little unsatisfied. One day, I was invited to Seira's house to study together. I was thinking that she must be a wonderful family and be filled with happiness...but then her amazing mother showed up to greet me! "Oh? Did you bring a boy? How cute!" Saki's mother looks like a wild animal with a strong libido. She instantly assumed I was her prey, and when her daughter wasn't looking, she started to approach my boyfriend's dick. With nowhere to escape in the house, my dick was already fully erect, unable to resist Saki's eroticism! My girlfriend's mother, whose libido is always on the verge of exploding, is a slutty, big-breasted slut who keeps going after my dick, even when her daughter is nearby!!!
