This is a 4K Lucky Shot of Sumire-chan, a cute girlfriend who rides her bike over to my place for sex! We met on a dating app recently, and she's a kindergarten teacher. Last night, we were at a company gathering and got into a conversation about cheating, and the next day she texted me saying her pussy was craving it. After a few drinks, she gets all cuddly. Today, I suggested we have some fun with cosplay, and she agreed with a smile. We quickly got her out of her clothes for a fitting session! Her shy demeanor while changing is so cute! With her in a sexy costume, we started our intimate session. We took turns teasing her nipples and pussy with a vibrator, dildo, cock tease, and clitoral stimulation. "I want more!" "I want you to fuck my pussy!" she exclaimed, revealing her dominant side early on. We changed into swimsuits and had some hot oil play in the bathroom. She was so eager for it, she even tried to apply the oil to her own clit! After getting her off with intense oil play, we went back to bed and changed into another costume to continue our sex. This time, Sumire-chan took the lead! She started with a deep kiss after sharing a drink, then licked my ears and neck aggressively. Her pent-up desire was unleashed, and she was in a very horny state. I teased her by slowly inserting my cock into her pussy, making her moan loudly. When I felt the right moment, I thrust deep inside her, making her cum explosively. "I want to be fucked hard!" she cried out as we switched to intense thrusting, and she came again and again! We moved to doggy style, and she begged me to "hit her hard." "Oh no, I'm cumming again!" she exclaimed as she came yet again. We continued with intense thrusts on the floor, and then she said, "I want to be on top now..." She seductively moved her hips, grinding her clit against mine. We had intense sex while I teased her nipples and kissed her. After she reached her climax with her own hip movements, we switched to thrusting from below, making her cum again with an intense shrimping motion. The climax was at her normal position, and she reached a huge orgasm, saying, "I love your cock so much!" It was a passionate exchange of pent-up desires! We enjoyed three different sexy costumes while fucking her slender body relentlessly. This was the best private sex ever!
