I Want Your Sex
by Limey Lady
What happens when two lesbian couples meet by chance? What when two of them have significant history as a previous pairing? Because the insatiable and ever-practical Heather is involved, the two exes bury old hatchets and reunite for a weekend while Heather cops off with the other "spare" partner. But that leaves a pairing combination still not tried.
Obviously it's time to play wife-swapping!
