I heard the giggling downstairs and turned my music up slightly to drown it out. Amanda, my girlfriend, was hosting her first lingerie party for her friends. It was something she had decided to do in her spare time and, seeing as she was a natural born sales-person, I was sure she'd manage to shift a few bits and pieces to her friends. I had been banished to the bedroom for the night, as there was going to be 5 drunk, giggling girls trying on underwear in my front room. How I wanted to be a fly on the wall there! I fondled my balls casually as I imagined them all spending their hard earned money on lingerie and sex toys, modelling them for one another.
The party had been going for an hour or so when I heard footsteps creaking up the stairs. I paused my music and listened closely; whoever was approaching was trying to be sneaky about it. Suddenly the door burst open and all four of Amanda's friends burst into the room giggling and stumbling, a couple still with wine glasses in their hands. There was her sister, Rhia and three other friends, Jemma, Nicola and Hannah, but no sign of Amanda.
'Nathan!' Rhia said, giggling. 'I hope we weren't... you know... interrupting anything!' The insinuation that I had been wanking was clear and brought fresh giggles from the rest of the girls. I flushed a little and smiled.
'Hi girls... are we all a bit giggly and tipsy?'
'No' Jemma pouted.
'We need your opinion on an outfit,' Hannah stated, reaching behind the door and dragging Amanda into the room. 'She doesn't know whether you'd like it or not. What do you think?'
'Wow,' was all I could gasp as my scantily clad girlfriend was thrust before my eyes. She wore a see through, baby pink nightgown which fell to the top of her thigh and left nothing to the imagination. Her large, natural tits were clearly visible through the fabric, she had taken her bra off and her nipples stood proud and erect on her chest. She was proud of her slim and slender body and obviously felt no embarrassment at being almost nude in front of her friends. She still wore her knickers, but beyond that, she may as well have been nude. She adopted a mock look of shyness as she twirled for me. My cock began to swiftly stiffen in my boxer shorts.
'Well?' Hannah asked, raising an eyebrow and glancing towards my crotch, where a tent pole was beginning to form.
'I love it.' I said finally, drinking in her youthful, firm beauty.
'We can tell!' Jemma said, drawing all attention to my state of arousal; the fact that I was wearing loose fitting boxers and just a pair of tracksuit bottoms over, had given plenty of room for my cock to grow and show. A moment of silence filled the room as I felt all eyes staring at my cock. An almost overwhelming desire to pull it out and show it off nearly got the better of me. I was proud of my cock, which was above average in length and was nice and thick, I wanted to squeeze it roughly and make the purple head swell and throb for the girls. It was now so stiff that it ached; finally it was Nicola, a shy looking, geeky girl with long, straight black hair that broke the silence.
'We should leave Nathan in peace,' she said, although her eyes kept flicking to my throbbing cock. The girls reluctantly left; on her way out Amanda tipped me a wink and shook her tits side to side for me, causing them to jiggle on her chest.
'Save that for later,' she mouthed as she left.
I was shocked at what had just happened, but put it down to the wine that the girls had been drinking. Amanda had never been shy and retiring with her body and she loved to get naughty in public places; but she had never so brazenly bared herself before her friends and sister like that to my knowledge. She also seemed quite comfortable with everybody checking out my cock too; I was intrigued to see if anything else would happen as the night went on.
Inevitably, something did happen. Around a half hour after they had burst into the room, I heard my name being called from downstairs. Feeling nervous and excited I padded down the stairs and knocked on the living room door. 'Did you call me?' I asked through the door.
'Come in Nathan!' I heard Rhia's voice from within. 'We need another opinion!'
I pushed the door open, expecting to see my girlfriend in another revealing outfit, but the first person I saw as the door swung open was Amanda; who had re-dressed in her jeans and shirt. As I stepped into the room it became clear to me that the opinion was required for Hannah, a very slim and slender woman who had large, natural breasts for her frame. She was quite plain looking most of the time, but had a subtle prettiness; her face was framed by her naturally curly brown hair. I gasped as I saw the outfit that she wore; it was pure slut schoolgirl, her breasts were almost bursting out of the tight shirt, which had only one button and left her smooth, flat midriff completely exposed too. The skirt covered less than a belt would and her red French knickers were clearly visible; black fishnets completed the outfit, showing off her slender, toned legs and pretty little feet. She twirled as I stood, mouth agape, giving me a great flash of her tight, round ass.
I looked to Amanda who was studying my reaction, her face slightly flushed. 'What do you think?' She asked; I noticed her nipples poking through the fabric of her t-shirt and realised that she remained bra-less. 'Will her boyfriend like it?'
'I think so.' I answered, mouth dry and cock rising to attention as I drank in the sight of Hannah from head to toe, staring at her chest, willing the button to give and allow her breasts to spill free.
'We don't have to ask if you like it.' Rhia giggled as I realised that once again, my cock was the centre of attention.
'While you're down here, we've got a favour to ask you honey.' Amanda spoke to me, but stared straight at my cock. 'Jemma wants to buy one of these comedy thongs for her husband,' she said as she pulled out a thong which had a banana as a pouch. 'But she wants to know what it looks like on, and you're about the same size as him.' She threw me the thong. 'Be a dear and model it for us.'
