What I do in these cuck situations i start out with her on all fours. Start with spanking and adjusting her legs , keep her ass high in doggy then we warm her ass then warm her emotions, Next is service on my big cock and proceeed to fucking her hard from behind and continue her whipping. Since she is essentially cheating on you she wont be treated like a princess,,, I will usually end up taking her ass and we keep her face down and asss up. It works
