It had been days since they last played. Life and work taking up the time that could be spent together. The Alpha had his mate, an omega. She though was a beta female; she respected and loved the omega. She bowed to the omegas wishes because she was the Alpha's mate.
The three of them were at a play party. Where all manner of debauchery happened. Spankings, rope, bondage, sex of all kinds. The Alpha had one of the bedrooms booked for the night. He was planning an event with the three of them. The beta knew she would be watching but beyond that she had no clue what the Alpha had planned.
The omega and beta went off to change into their naughty clothes for the night. The beta went down to just her pretty underwear and the omega went down to just her socks ready to walk around in her birthday suit.
The pair greeted the Alpha and knelt before him. The beta, a little bit behind the omega. He loved their submission to him and patted each on the head with words of endearment to each. Tonight, would be an interesting challenge for the beta. She would be forced to watch the alpha and omega, not being allowed to join in on the pleasure.
They walked around greeting people and talking for a bit before going back to the room. The beta was nervous, but managed well by watching that the omega was safe and comfortable. If she wasn't freaking out, then the beta stayed calm.
Back in the room the omega watched the alpha bind the arms of the beta. She herself had no interest in the beta beyond friendship. That didn't stop her from enjoying watching her mate be dominant toward others.
The betas arms were secure behind her back. The alpha then pulled out a toy from the bag he had. It was the we-vibe the beta owned. The device controller in his other hand.
"Spread your legs" he commanded softly.
The beta did as she was bid. Spreading her legs to allow him access to her cunt. He slipped the underwear to the side and slide in the toy. She was surprised at how easily the toy went in. Gods she was soaking already at just these simple actions. She moaned softly in her throat as the toy gently filled her. The outer portion moving her clit just a little, exciting her further.
