Saturday morning, I wake up to find my senior from work, Karen-san, right next to me...! Wait, did we do it yesterday? Karen-san is sleeping peacefully beside me, wearing sporty lingerie that shows off her cleavage and the curve of her ass, with her pussy completely exposed. I didn't notice last night, but you were wearing that kind of lingerie. Ahh, so erotic. I can't help but get a massive morning wood. One time or two, it doesn't make a difference... "...Wait, what are you doing, ahn!" The combination of her beautiful waistline and that lingerie makes me feel like cumming, so I just insert raw. Pounding her pussy right after she wakes up, one, two, three times... I couldn't hold back and creampied her. "Ah, no, I'm cumming!!" I get even more excited seeing Karen-san cumming like crazy from my cock even though she has a boyfriend. I completely forgot my plans and fucked her wildly all day! Her unusually hot appearance had me piston-fucking her until my sperm ran dry, ejaculating 12 times! With unstoppable, runaway pistons, I creampied her over and over again...
