A few months later we had a few days off together. I didn't realise what she'd been doing on the Web, but I found out who she'd been talking to! I was out shopping for her while she had a lie in. She texted me to tell me to get certain food items, and to pick up her Indian friend, who I'll call Raj for anonymity, from his shop. I did this, knowing he'd always flirted with her, and her penchant for Asian men was still strong. He told me she'd invited him for coffee and she had arranged a little party for her birthday. I wondered naturally why I wasn't told, I could have helped, but as always when she switched on her Mistress role, I knew I'd have to obey or get a heck of a thrashing, maybe her big whip too. When we got home, she was still in bed, and Raj told me to put on my gimp mask, backwards, and he led me to the bedroom, with his hands over my ears. I could hear Lilith laughing and giggling still. Suddenly Raj lifted off my mask and let me see Lilith's "Birthday Surprise." She was naked with the sheets thrown off, lying like Venus, with her legs wide apart... and another Asian guy, naked between her legs. She laughed ecstatically at my expression, and lifted a leg slightly so I could see his dark brown shaft embedded in her beautiful pussy. "Surprise Surprise!" she laughed! I felt myself blushing and I knew how she loved to humiliate me. Yes, I enjoyed it too, in a perverse self-denigrating way. She ordered me strictly to hurry and remove my clothes, and that her feet needed attention. I knew what she meant. As soon as I was naked, and Raj had handcuffed me, I knelt on the bed and began to lick her sexy toes. Of course she was bouncing a bit as the dark stranger pleasured her, and she bitched at me whenever my tongue slipped from her foot. I saw Raj undressing in the corner of my eye, as I delved in between her toes. She mocked me, "See his big willy in me? Whooo, woooo! lick my toe ring too! Any toejam in there? Better eat it if there is! Hee hee, my poor footcuckold!" This was just the beginning of the session...
