When the female partner is giving the male oral by nibbling on the end of his penis while he places his penis in the space between her armpit and torso while he thrusts through the gap to give the mouth more room to nibble.
NB: This only works for a penis over 8" in length.
While I fucked Allie's armpit her nibbling on cock in the Armpit post nibbling position made me blow sweet load.
