Steven was sitting on the living room couch being masturbated by Jack while Tiff and I gently sucked on his nipples. The boys turned to kiss each other and Tiff ran her fingertips over one of my breasts. Steven was just about to orgasm, so I lowered my head from his nipple, ready to catch it in my mouth.
Unexpectedly, Samantha walked in, and she spoke before we knew she was there. 'What's all this, then?' We all turned to face her just as Steven spurted.
For many weeks, I'd been meeting these three wonderful classmates every week at Samantha's flat. She was the big sister of Jack, and she would let him and Steven use the place on a Friday night while she was out with her friends. Except we'd never met her because she didn't know they'd been sneaking Tiff and I around for a bit of fun for weeks. Up until now, we'd always managed to leave before she came back.
'You didn't tell me you had women around as well,' she continued, sounding amused rather than angry.
We were all naked, so we made to put at least our underwear back on, while Steven grabbed a tissue to wipe up.
'No need to cover up on my account. None of you have got bits I haven't seen before.' Even so, I still hurried to put on my bra. I'd never been referred to as a woman before, though, so that made me happy.
'Um...' said Jack, his erection bulging behind his underwear. 'What are you doing home? It's early.'
'Forgot my purse.'
'Oh. Right.'
She faced me and pointed at my face. 'You've got spunk on your cheek.'
Without thinking, I scooped it into my mouth.
'So how do you all know each other?'
Jack stuttered. I don't know what he was going to say, but Tiff took over. She told Samantha about our masturbation group at school after games class, while Steven and I chipped in with extra bits and pieces about what we did on a Friday. We told her we always started our sessions with solo masturbation, then moved on to pairs, then maybe something as a group, like just then.
By the end of the story, Samantha was lapping up every word we said. 'So are you going back to do games next year? Start it up again.'
'No,' I said, 'everybody dropped games the moment they could.'
'Except Jack,' added Tiff. 'He says he wants to own a gym one day.'
Jack hadn't contributed to this explanation, so Samantha turned to him. 'And what's your story?'
He said nothing.
'Why the secrecy? Why didn't you just tell me you had some charming women round?' She winked at us girls. 'You know you can tell me anything. I'm not mum.'
He said nothing but looked at a point on the floor.
'I knew they were gay though,' she said to us. 'They've always been cute together.'
'I'm not gay,' said Jack.
'Jack's gay and Steven swings both ways.'
Steven now also looked at the floor, seemingly in embarrassment.
'I'm a lesbian, out and proud. I've got gaydar. I know who bats for what team without seeing them wanking each other off.'
'You don't look like a lesbian.' I blurted out without thinking. For one moment, I thought she was going to throw us out. 'Sorry, sorry,' I added, 'I didn't think.'
'I know, I'm not butch; it just isn't me.' She turned back to the boys. 'And I see your condoms in the bin all the time, and little empty packets of lube. From what you've said, that's been going on longer than these ladies have been round.'
