“Ok, no abnormality”, he says with a smile. “Please, lay there face up”, the doctor points to the examination couch. I obey. He stretches my l...gs and inserts the speculum to examine my vagina. “Wonderful”, he says, “everything as it should be. Now get on your knees. The next procedure maybe a little unpleasant. I will examine your anus.” A little shy I turn around and offer my backside for the examination. Dr. Milton puts on rubber gloves and drops some lube on my backdoor hole. I do a little. As I wasclutched in this vise grip, Janice tensed up...and came."Ohhhh..." she sighed, releasing me.And that's exactly when I felt it: my penis jerking, waves of pleasure,my balls clenching. I had come too.***I lay in bed awake that night, going over and over what had justhappened. Next to me, Janice was snoring softly.Why had I done it? Why had I just bent over and let Janice spank me?And did I really find it pleasurable? If not, then why had it been soeasy to orgasm afterwards?I looked over. Please find what you've come for higher up the room! But 'no'. Of course she (and it WAS a 'she) came marching straight down to where we were...... but when she came straight round the corner and I saw my 'friend' whose name was 'Janet' grinning up at me I knew I'd been set up by two women in their mid to late thirties and for the first time I began to get a little worried. Apart from anything else they were sisters! 'Well now, what are you two doing?' she enquired with a grin on her face. My head was moving backward again and again in enjoyment and he was continue to pump my bum and in between he also pumped my boobs many times under my top. A sexy sound of fucking with movement of his cock in and out was making us more mad and more sexy. We were at our best and I was riding him giving him all the pleasure of a good sex act. My hands started to feel some pain in process of holding my weight and I put both of my hands on his thighs under my thighs. It was little comfortable for.
