Girlfriend’s cute little sister begs “please cum in my pussy” and gets a thick dripping creampie while sis is away

My girlfriend left for work and her adorable 20-year-old sister stayed over “to study.” Ten minutes later this innocent-looking cutie with the big eyes and perky tits is sneaking into my room wearing nothing but tiny shorts and one of my t-shirts, phone already recording from the nightstand. She climbs on the bed, straddles me, and whispers “I’ve wanted you forever… please cum inside me, I’m not on anything.” The camera catches every forbidden second in perfect homemade style: she pulls her shorts aside, slides down raw, gasping how much thicker I am than her boyfriend while riding slow at first, begging the whole time “cum in my pussy, breed your girlfriend’s little sister.” Her tight body bounces faster, cute face twisting in pleasure until she cums hard, pussy squeezing me like a vice. I can’t hold back — I grab her hips and pump rope after thick rope deep inside her fertile pussy while she moans “yes, fill me up!” Close-up finale shows her spreading wide, my load gushing out of her pink hole as she giggles nervously and says “we’re definitely doing this again before she gets home.” 100% real risky sister-swap creampie that felt way too good to ever regret.
