She does!

Emma studies you for a moment, clearly undecided. Which makes sense – you’re not bisexual yourself, but it must be a little weird perving on people of your own gender, right next to your straight partner.

You’re about to tell her to forget it when Emma nods suddenly. ‘Okay. Fine. I suppose that’s fair.’ She lowers her eyes. ‘And I have to admit, I do want to see what type of girls you find attractive.’

That sounds slightly dangerous, and Emma clearly notices the look of apprehension on your face. ‘That sounded like a trap, didn’t it? Don’t worry.’ She squeezes your arm gently. ‘I just want to know the sort of things you generally like in a woman, you know? It’ll be interesting. Maybe I can pick up a few tips.’

You kiss her firmly. ‘Fuck that,’ you tell her, smiling against her teeth. ‘You’re perfect, Em, you’re already the fucking ideal. As far as I’m concerned,’ you add, as Emma opens her mouth to object. ‘And don’t tell me you’re not my perfect girl, because how the fuck would you know?’

Emma’s mouth works for a moment. ‘Rude,’ she says softly. ‘But okay. Where were we?’

‘You were about to tell me how you’d fuck Bonnie Wright,’ you tell her, smiling. ‘While I jerk off. Sound good to you?’

Emma snorts gently. ‘While you jerk off? What kind of girlfriend would I be if I allowed that? I’ll jerk you off, thank you very much.’ Her small hand slips into its familiar position around the base of your cock.

You hold your hands up in surrender. ‘Even better. So…’

Emma’s hand slides up and down your cock a few times, caressing the head, getting into a rhythm. ‘So…’ she murmurs. ‘Well. I suppose… if I was going to have sex with one of my friends… and if it did happen to be Bonnie, with her lovely red hair… it would probably be back at that pool, behind the trees, where it’s just the two of us.’

‘No Katie, no Evanna?’ you ask hopefully. Emma pauses in her cock-stroking momentarily.

‘Who’s telling this story? You or me?’

‘You,’ you mutter, subdued. Emma shakes her head, returning to her work.

‘Fine. Let’s say that Katie and Evanna have just gone in for a moment to dry off. I imagine they’ll be back, though. Perhaps they’ll even catch us in the act…’

You groan, as Emma’s fingertips glide up and down your shaft, agonizingly soft.

‘I’m innocent, remember. I’ve never even seen a girl’s breasts before, not apart from my own. But Katie’s just dared Bonnie to take her top off, and Bonnie’s actually gone and done it – and I can’t take my eyes off her.’ Emma squeezes your cock hard, running her small pink tongue over her lips. ‘Her nipples are sticking out so much in the cold night air, and her boobs are much bigger than I thought… and she doesn’t seem to care, that’s what’s so sexy about it.’

‘C-cups, you said?’ you interject, unable to help yourself. Emma glances down, a faint smile on her face.

‘As far as I can tell. They’re definitely bigger than mine, and I’m only a B-cup… and I know I shouldn’t be comparing them, shouldn’t even be looking, shouldn’t be staring at her, but I just can’t seem to stop myself.’ Emma’s grip on your cock becomes tighter as she jerks you, and you groan under your breath, imagining it. ‘She’s so beautiful, with that dark red hair falling around those hard pink nipples… and I just want to fist my hands in her hair and kiss her, and touch her boobs, and maybe even have her touch mine…’

‘You’d have to take your top off, first,’ you point out. Emma responds by jerking your cock even harder.

‘Maybe I will, then. Maybe I’ll decide that Katie and Evanna have been gone for a while… and maybe I’ll persuade myself that they must have been distracted. Maybe I’ll think to myself, “they won’t come back for ages”. Maybe Bonnie will glance down at my boobs, and say something provocative, like… “you joining me, Hermione?”’

Emma’s breathing becomes louder as she slips a hand between her own legs, beginning to masturbate herself even as her hand slams up and down your cock. ‘Maybe one of my bikini straps will fall down… and then the other. Maybe Bonnie will swim over, till her nipples are almost touching me, and reach behind to my bikini clasp. Maybe she’ll unclip it, and my little flowery bikini top will just float away… and I’ll be topless with another girl, for the first time ever, nipples hard and water clinging to my boobs.’

You’re past words, now, cum building in your balls. Emma presses two fingers inside herself, gasping slightly. ‘Oh, fuck… maybe Bonnie will close the distance between us, pressing our nipples together… God, maybe she’ll hold my boobs in her hands… feel the weight of them in her palms, and maybe I’ll do the same to her… feel her lovely big C-cups. Maybe she’ll lean in for a kiss, and I’ll be so horny and confused and excited that I’ll just go along with it…’

Emma’s fingers are sliding in and out of her vagina as she talks. ‘Maybe I’ll kiss her back, and squeeze her nipples, and run my hands along the curve of her little round bottom… and maybe she’ll take that as permission, maybe she’ll slip her fingers into the front of my bikini and touch my clit for the very first time. Maybe I’ll gasp, and shake, and let her do all of it… maybe she’ll press her fingers inside me, while her thumb strokes my clit, softly at first – then harder and rougher as I moan and squirm and abandon myself to it, as I squeeze my cunt around her fingers and beg her to make me cum, right there in her hand…’

Emma trails off, and you open your eyes unhappily. ‘And then?’ you demand.
