Normally my sis lounges around the house all careless-like, but for a teen dude like me, that’s straight-up sensory overload—sometimes I can’t help seeing her as a proper woman… Then one day, she lands a gig at a blokes’ spa!

She begs me to be her practice dummy, and I’m like, “Ain’t that the sketchy kinda massage though?!” Next thing I know, she’s working them groin muscles with flexi-fingers, her skimpy uniform showing off every curve—boom, instant full-mast boner! She spots it, grabs me warm-handed, and goes to town till I’m leaking pre like a busted tap.

Turns out she’s getting all fired up too, going down proper on my shaft, even taking the boys in her mouth, oil and spit making a right mess! Then—no going back—she hops on cowgirl-style and rides me proper! “It’s all just practice…” she says, even as things escalate wilder than the massage itself.

Forbidden sis-action! The guilt of keeping it from our folks, her sucking skills leveling up, unstoppable lust—we’re coming again and again, no brakes! Today’s another round of hitting all the right spots, sending me into top-tier ecstasy.
