feeling like the bigger man

SO in a complicated scenario my parents were out of town (im 18) and were worried I wouldn't be able to take care of myself so they left me $100 for food and told me to always try to have someone over so I wouldn't get robbed, even though we live in a pretty safe part of town. Theyre always trying to take care of me like that its weird. Any way Charlie had this girlfriend with a bangin pair of tits and the most adorable pouty face. Her and I talked some and were considered friends because Charlie and I hung out a lot and she was there kind of just by association. She comes into the story because our parents were good friends and they always came over for dinner. Well my parents being cautious as they were asked her parents If she could come over on sunday night and make sure all was good with me. A weird circumstance but they thought it was normal and her and I were chill so I was like eh whatever well talk for 10 minutes then shell head out. Sunday night came and she came trotting to my door playful and happy like she was hanging out with an old friend. I invited her in after 10 minutes when I thought shed met her queue to leave she suggested we make mac cheese. I was cool with it bc she was being so fun and flirty and her boobs looked massive and perky in her red lace bra. I felt kind of bad thinking about Charlie's girl but she was initiating and it wasn't like I was gonna do anything besides talk to her. we devoured the food and again I thought she was o her way out when she suggested we turn o the TV because apparently her parents wanted her to babysit me like a child. Again I really didn't mind because she was like an angel and the tease of her flirting and me not being able to grab her was getting be rock hard. we settled down on the couch under the same blanket which was strange but things were about to get stranger. Twenty minutes into what was turning into a netflix and chill with my friends girlfriend were were laughing together and her hand sort of grazed my fat erection under the blanket. I thought to myself "of shit things just got weird and we cant ever talk again" wrong. Her eyes lit up in this outrageously cute look of shock and she said in a giggly voice "holy shit what do you got under there??" subconsciously I put my hand on her knee and rather consciously she slid her hand into my sweatpants and gripped my fat shaft. I sputtered out in shock "what are you doing?" and she responded with a horny and pouty " your cock is HUGE" I started to reason out of it but my undisclosed desire to have her pump my load onto her taken face was apparent in my tone. in a cute and worshipful tone she said "your cock… is SO much bigger than Charlie's!?… ok I'm here to take care of you and that's what I'm gonna do…" she started jerking me tenderly and skillfully and slowly accelerated. she put her face up to mine and I started kissing those lips that belonged to Charlie and playing with that tongue that I shouldn't have been playing with. However guilty I would've felt was masked by revved up she was getting by me desecrating her loyalty to a smaller guy. She had been jerking with such vigor that my dick was ready to expload and I told her so "oh my god I need this dick and I need a real mans cum" she sad and she fell to her knees. my pants were ripped off and she started kissing and licking my cock as if it were her savior. "I'm such a little whore for you and ur cock" she exclaimed and shoved my tip into her mouth and grabbed my nuts. a blast of cum exited my dick into her mouth and I marked her as mine and she swallowed my load in full horny submission. I felt like such a man with my cum tripping down the lips of my friends girlfriend while she kissed my cock and made known how much bigger I was than her boy. it was one of the greatest moments of my teen years and she has never forgotten who she really belongs to
