The guy behind the register smiles at Erika and says,"What can I do for you?" Looking for some fun items. Like collar, leash, nipple clamps and stuff,... I said. I can practically feel Erika's face getting red from humiliation."Dog collar and leash, isle 3. Nipple clamps, isle 5. Dildos and vibrators, isle 2," the cashier says looking right at Erika who was now looking at the floor and avoiding all forms of eye contact.I walk to isle 3 and Erika runs up behind me. In isle 3 I look over some. When it finally came, the climax was intense. I cried out loudly and incoherently, my arms giving way so I slumped forward. It felt like a fire was spreading from my butt, so powerful it was near the edge of pain, like no orgasm I had had before. Spunk poured from my cock, mostly splattering on to the carpet but also flecking my chest as it still flapped with Pat's thrusts. He continued to fuck me, even as my ejaculation subsided and the sensation in my butt became less pleasurable, I was too. I was a little nervous because it starts mild but eventually moves to the guy sucking her cock and then her fucking him. As we were watching, both guys said they would let her suck their dicks. As the bi stuff started to steam up, the guys asked if I had been with a trans woman. When I said yes, they started to ask more detailed questions. I eventually admitted that I was bisexual and had explored a lot of stuff. When the guy started to suck her dick, they asked if I had done that. I admitted I. Mmmmm!" Robert slapped her ass hard as he pumped her harder. Even the pillows couldn't keep her sexual noises down; she just got louder and dirtier. Robert enjoyed sessions like this with his wife, it was always so exciting, and it was like fucking a whore and not feeling guilty about it. He was also hugely turned on by the sight of her ass crashing back into his groin, the smacking sounds of their skins making high velocity contact. Oh sweet! He thought, ‘so glorious, watching my cock.
