Teacher Tsujii used to favor me, but once she found out I had a girlfriend, her attitude changed completely. "Hmm... Miura-san is about a B-cup, right? I'm an H-cup..." For a pubescent boy like me, resisting the temptation of big breasts was impossible. Using her massive tits to full effect—titty fucks, blowjobs, handjob with nipple rubbing, breast-squeezing sex, and cowgirl position with her huge breasts bouncing wildly—she unleashed her aggressive woman techniques to make me cum again and again. Sorry... I love my girlfriend (you) a lot, but I love big breasts even more...
