I (21FTM) have a habit of masturbating with the window open. I was humping a pillow on my bed, grunting and moaning when I heard someone tapping on the window of my bedroom. When I looked over, there was someone in an Amazon uniform standing there. Shit, I forgot I was having a package delivered today… He asked if he could give me a hand and I was so horny that I just told him the front door was open. Not long later I heard the bedroom door open and I saw him enter with his pants starting to form a tent. It looked like he had a nice package there… He stripped his clothes off before he reached the bed, where I was already naked. My hips were raised on a pillow and my legs were spread apart ready for him. He quickly stripped down before straddling me with his cock already hard. He slide a finger straight into my wet pussy and started rubbing his thumb on my hard clit. I felt one hand reach up under me to start fondling my nipples as he kept working on my pussy and clit. Then it stopped. He took both his hands off me and I moaned and began grinding my dripping pussy into the pillow again. Just a few seconds later I felt something at the entrance to my pussy. He started pounding me harder than I had been in my life. I was a dripping, moaning mess as his balls hit my clit over and over. He put one hand back up on my nipple and used the other to start slapping my ass. I could feel myself starting to pulse around me and suddenly he pulled out. I felt his cum hit my ass as my pussy clenched and pulsed. He jumped off me and put his uniform back on and left as quickly as he came.
