A ptty blow job is given when your girl wont fuck you, but you wont take no for an answer so after begging she offers you a blow job to shut you up. But its not a regular blowjob its a bullshit cover up for her lack of sexual drive
Not even cumming all over her face would make the pity blow job feel satisyfing
" Babe im horny lets fuck !" " No im sick i dont feel good, how bout a pity blowjob" " Na id rather go watch 60 minutes!!!"
