I can't stop thinking about threesomes

Specifically involving another woman who'd be so gentle as she guides me through sucking his cock, holding my hair back and fondling my tits as she whispers into my ear what a good girl I am. Encouraging me to take it deeper into my throat as she teases my pussy.

I imagine her helping him slide his thick cock into me, all while rubbing my clit and showering me in praise. And when he's finally in, she pushes my face into her huge tits, making me suck on them before sitting on my face until she cums. It makes me so horny thinking about how I'd need to put extra effort into eating her pussy, needing to focus on her pleasure even when I'm being pounded.

Ideally, it would end with him emptying his load into me, followed by my female lover telling me how well I did before cleaning it up with her mouth.

God, I really need to befriend a bi girl who'd be down for this.
