A quick warm up
Brent now removed his shirt and walked purposely towards Mark with his black shaft fully erect so that his foreskin had no option but than to be completely rolled back. Behind him the other guests watched him in eager anticipation, none more so that his wife who, although satisfied for now could feel herself getting juicy once again as she always did when she was able to see Brent get pleasure in 'other ways'.
Rather that facing the wall as both the women had chosen to do, he instead sat so he could watch Mark's cock twitching as he lowered himself onto the seat directly above his head, carefully positioning himself so his proud hardon and balls were hanging slightly above Mark's face.
Mark immediately felt the heat of the big black cock on his lips and was surprised to find himself licking his lips in anticipation. Amelia knew that feeling well having many years of intimate moments when Brent had presented himself to her. Sometimes she would play the part of the willing slut, demanding her mouthful of stiff cock. At other times she would be the submissive - which Brent particularly loved - pretending that she was encountering him for the first time and acting in the same shy way she did when seeing Brent's erection from below as he told her exactly what his needs were.
'Lick my arsehole #11', said Brent in a forceful tone that Amelia knew well and Mark hurried to oblige him running his tongue around Brent's rim as his own cock twitched again.
