After enjoying outdoor exposure with my sister-in-law using a remote-controlled vibrator, we checked into a hotel. As soon as I turned on the vibrator's switch at the entrance, she started moaning loudly enough to be heard outside. I told her to masturbate here, and as she did, her body convulsed so much that she couldn't stand. When I directly stimulated her clit, she screamed loudly, begging, "Please, torment me," "I'm coming, I'm coming!" I took her to the room's window and forced her to undress, saying, "Someone will see!" While trembling with excitement, my M-sister enjoyed being watched. Just touching her nipples made them hard, and her vagina was soaked. The aroused sister said, "I want your cock," trying to touch mine, so I blindfolded and restrained her hands, increasing her sensitivity. Turning on the vibrator again made her body convulse with pleasure. When I removed the vibrator, strings of love juice clung to it (laughs). Because she lost her sight, even slight stimulation made her moan louder than usual. "Touch me more," she begged, so I used an electric massager on her, causing her to instantly scream, "No more, I'm coming!" Seeing her like this made my cock hard. Slapping her ass made her moan, "It feels good," "No, no, I can't take it anymore, I want to suck your cock," said the M-sister pervert. Not letting her touch me but teasing her instead, when I fingered her, she squirted love juice and came repeatedly. "I want to suck," she said, deeply taking my cock into her mouth, servicing me. As a reward, letting her suck my cock made her scream with pleasure. Wanting to torment her more, I positioned her by the window so outsiders could see, using doggy style. Every time someone passed by, she tightly gripped my cock, this perverted act. Excited, I vigorously thrust in normal position, reaching climax and asking, "Who feels better, brother or me?" She said, "This cock is the best," making me happy, but too excited, I ended up shooting a large amount of sperm into her stomach. "Next time, I want you to come inside me..." she pleaded, so next time I'll do it inside (laughs)
