training my way into a taboo thrill

so i’m this personal trainer, right? been dating this chick for months now. she’s really into healthy living and stuff, but you know how it is when u got your routine down. one day we’re just out shopping and her friend mentions they have this crazy idea to get couples to try something new in their relationships, like swapping partners or some shit. my girl laughs it off at first but i could see the wheels turning inside her head. next thing you know, we’re talking about it more and more, getting kinda curious about what that would be like with me playing a different role for once. i mean, she’s been all about fitness and health since day one, so being this strong athletic type in bed has worked well but maybe there’s something else too? anywho, last week we went ahead and did it, took turns spending an hour each with some other fit guy at this fancy couples retreat place. surprisingly fun and hot actually. felt kinda naughty to be on the receiving end for once, her working my muscles instead of me hers. definitely brought us closer but also made me realize i might like exploring more of these kinds of roles in our sex life
