I'm the owner of a guesthouse located beneath my home, and when Yuka, a plump big-breasted girl, arrived by overnight bus, I welcomed her and began showing her around the room, unable to take my eyes off her body. She said she came to visit a friend, but I grew curious and secretly installed hidden cameras at the property to observe her. Waiting for her return, I carefully watched her through the cameras—her short skirt, her panties fully exposed. Seizing the moment after she got out of the bath, I sneaked into her room with a gift, and though surprised, she happily welcomed me. I slipped a date drug into her drink and successfully got her aroused. Late at night, under the drug's effect, Yuka fell asleep, so I climbed on top of her and finally indulged in the long-awaited sex. I poked her nipples, groped her big tits, and stimulated her pussy until she climaxed. With a moaning face, she reached orgasm after orgasm, riding me and taking me from behind intensely. While stimulating her big breasts and pussy, I creampie'd her, then left her behind as I returned to my room. Yuka was truly an irresistible woman.
