A boxing session turns sour after Sumiko agrees to suck the camera man off if he can knock her down three times. Rules are set but the POV character continues to break them due to the amazing agreement set between them. The POV character has Sumiko right where he wants her now even stripping nude and attacks her with a flurry of blows until finally a brutal knock down gives him the victory. This match doesn't include the blowjob that came after but it does show what happened first ;)
