I'm looking for one manga that has a guy nicknamed "biscuit" or something like that, he has a big dick and then there's 2 girls from another class than hear the rumor about his dick, one of those girls seems to be shy and he thinks that is inexperienced at sex tries to suck him but his dick is too big, they then fuck.
The other girl (she is taller than the shy one) is looking at them meanwhile, then, later gets fucked.
It ends with girls still joking about his big dick (wtf japan?) but he is now confident because he knows that his dicks made two girls happy.
Has anyone read it?, I can't remember the name and has been looking for it for quite some time.
Also sorry for the bad english, i'm still learning.
