IPX-710
Yume Nishimiya is a slutty schoolgirl who will come immediate to your place if you call her for a blow job. First scene is just that, she comes and sucks the guy's cock. The next time he texts her she arrives but surprises him by bringing along another dude who she said she just met in at the subway station so she invited him to come along.
The original guy is kinda reluctant but Yume says it's just for blowjobs so he agrees to let her suck both cocks together. The new guy cums so he steps aside and original guy starts fucking Yume. After a bit, the other guy recovers so he starts begging to join in on the fucking. Yume is down for it but the original guy is still reluctant but eventually agrees so they're both on the horny Yume after that. Great scene.
Unfortunately, after this scene they switch the Yume sucking other random guys outdoors and in a bathroom instead of continuing to escalate the theme in the same guys apartment. It would have been interesting to see the original guy's reaction as more and more guys gather in his apartment to fuck "his" fuck toy girl Yume.
