when i was high school my grandmother stayed with us for a while and slept in the same room with me. one night after looking at porn all day i was so horny i decided to try to finger her while she slept. i waited until late in the night when i was sure she was in a deep sleep and snuck beside her bed, got my hand under the covers and up her night gown and into her pussy for a few seconds before she woke up. she screamed and grabbed my hand. i got it away before my parents came in the room. they asked what happened and i spoke up before she could and said i was just checking on her because i thought she stopped breathing and it scared her. she didn't correct me or ever tell my parents.
