A husband and wife have revealed how they've found the secret to relationship bliss after letting a 20-year-old woman share their bed - and look after their two young children.
Polyamorous mother-of-two DeAnna Rivas, 27, from Florida, says she's now planning a three-way wedding with her husband Manny, 28, and her girlfriend Melissa James, 20, because the set-up works so well.
The unusual situation came about after Deanna asked her husband if she could take on a female lover, saying their was a hole in the marriage that only a relationship with a woman could fill.
Manny was cynical at first but soon found he enjoyed the third person in his marriage, and invited Melissa to share the marital bed.
According to UKMail, having multiple partners is also beneficial in the bedroom.
DeAnna said: 'There are lots of benefits on the physical side - it is very adventurous.
'Sexually it is very interesting. We open up our marriage and our bedroom. We do everything.
The three, who share parenting duties over Deanna and Manny's children - Vaneza, seven, and Gabriel, four - plan to 'marry' each other in the future - although the marriage would not be legal in their home state of Florida, USA.
