sleep all together

once you go to sleep you all get in the same bed and your cock is in the middle as they both lay pressing their heads against your tits and their hands caressing your cock
you're barely able to rest between the boat's movement and the excitement...
in the next morning you wake the last one and look at the girls outside
"how is that we're moving? i thought you'd the motor off..."
"i got it off... it's no sense... unless it's the sea itself who makes us move..."
"but is it moving us in the right irection?"
you blush unsure "we'll have to hope so..."
then you turn the motor on and just follow the sea's direction, leaving the sun on your left
not knowing about it you're directing yourselves in south direction
