Ugh why!! 😑

So Because Of lockdown I’m stuck with my stepdad in the house most of the time so when I find a time to masturbate I jump at it. (I’m a teenager with a very high sex drive it’s a blessing and a curse) but half the time I go to masturbate and I’m really close and he comes home and I kinda get female blue balls so i wonder is it my timing it’s just so frustrating and once I thought fuck it if I’m really quiet no one can hear me (I’m not a moaner) I started I got close and he calls me downstairs to do something so I finish what he wanted me to do I went upstairs and started again and I get close and guess what he calls me again to do something so I don’t know what to do. does it just sound a bit suspicious to me
