This is the only way I am permitted to cum on the rare occasions I’m allowed out of the chastity cage. She will have me kneel on the floor at her feet, she’ll set a timer for 30s or 60s and allow me to masturbate furiously until the timer expires while she taunts me by comparing me to her lover and teases me with her body. She might allow me to hump her leg or foot if she’s feeling generous, while she calls me her horny little dog. If I’ve not cum before the timer expires I am locked up again frustrated and horny, if I do successfully cum I am required to lick up my mess from the floor and her feet before I’m locked up and then “pay” for my orgasm with a caning of my arse.
