The memory VTR of having sex with my best friend's girlfriend (Emi) at a birthday party of a university club. During the celebration at Emi's home, my best friend T had to suddenly return to work. But the party continued... As time passed and the alcohol kicked in, Emi's friend (Saki) got drunk and started flipping up her skirt. Emi was reluctant, but we joined in with the naughty pranks. Saki got even more into it and started sucking on a penis. Seeing this, Emi couldn't hold back any longer and joined in the sex.
