The piston-like movements accompanied by the sounds of slapping and climaxing, the deep kisses where saliva mingled, the vacuum sounds of saliva and pre-ejaculate being drawn together, the deep throat oral sex reaching deep into the throat, the four intense sexual acts, plus oral sex accompanied by lewd sounds, all while making obscene noises and engaging in intercourse, will make your penis rock hard under the stimulation of sight and sound.
