Male, 50

This is a new kind of s*x i have been getting addicted to. i am at my bf's house and he just untied me but almost every time now with him inside of me he forces me to c*m. it feels amazing even through the pain. i am shocked his neighbors have not heard me when he thrusts. this time he handcuffed my wrists to the headboard then tied my ankles together. i usually spread my legs further apart when he f*c*s me but this time i could not move. we have been having unprotected s*x.
