My glans squirts many times when my girlfriend's younger sister Sakura, who works in the product development department, gives me a duck mouth blowjob! I was forced to wear prototype pants with a hole at the tip, and in front of Sakura, I couldn't help but get an erection and my glans pop out... "If it stays big, we won't be able to get any data..." Sakura says, and she uses her duck mouth to give me a business blowjob! She licks and sucks only my glans, making me cum in agony! She then gives me a cleaning blowjob, saying, "Your underwear will get dirty," and then Sakura uses various methods to torture my dick, such as slippery satin fabric, glans stimulation, pantyhose squeezing, glans neck stimulation, and cowgirl riding, ignoring product development... #Team Leader P
