basically this story didn't happen today, it happened a few days ago. i was with my girlfriend at her house for the whole day celebrating her 18th birthday. the thing is she was horny the whole day, and by the time night time came around she drove me home in her mums car, as it was later at night and her own car broke down the night before. 

she parks a few streets away from my house and starts making out with me, no real objections from me. she moves down south to well less than pg things and starts giving me head. now i'll say right now i'm not the longest lasting guy, i last 5-10 mins on your average pornhub video, but i lasted 20 minutes and was feeling like a champ. 

i tell her that i'm about to cum so she goes down to swallow as to not make a mess but her necklace that i bought her for her birthday gets caught on my belt and by this point i can't stop myself from shooting my baby juice everywhere. i hit the motherload, it was a cumcano. it went everywhere, my jumper, jeans, window, the dashboard (didn't realise the dashboard at the time) all over her and my hands, her hair, her face and even in her ear! she told me she'd clean it up after i left and she dropped me off. 

fast forward to the next day and i get sent a photo from her best friend of the massive stain i left on the dashboard with the caption holy fuck that's a lot ahahaha. i've never spoken to her before so i basically broke the ice with a conversation over my massive cumstain in her mums car. to make things worse i text my girlfriend asking why she didn't clean it all up for, and she said she thought she did but she must of missed that spot, then she told me that her mum drove her dad to work that morning, and they must of seen that massive stain, i'm pretty much dead.
