My bedside alarm rang at 6am. I showered, dressed in slacks and a T-shirt then picked up the spare key to Eve's house.
Because it was raining hard it was unlikely that there was anyone around in this area to see me hurry next door, but I did notice a small cabin cruiser tied up on my mooring.
Clothes off; creep upstairs and follow the sound of sex emanating from the door to Helen's bedroom, which was open.
It was an extremely erotic sight. Two lovely young women, nude, shapely and well developed, were breast to breast with each other and both were really enjoying the situation.
Linda was lying across the bed on her back. Her legs were wrapped around Helen who was bending over her wearing a strap-on dildo. She was supporting herself with her hands placed eitherside of Linda's head as she energetically pumped the dildo into Linda's obviously wet sex.
I know it was wet because of squelch when her vulva smacked into Linda and the slurping and sucking noise it made each time that Helen's hips were pulled back in readiness for the next trust forward.
The smell and sounds of sex were very arousing, at least to me they were.
Schmesch - ooohh - sthrurrppthrurck, Schmesch - ooohh - sthrurrpthrurck.
That's a background noise I could live with.
I went back along the corridor to what would have been Eve's bedroom. I removed the lube from the bedside drawer and sprayed my cock before returning to the lovers.
This had not been part of my original plan; that had been for me to uncover Linda's shapely body and interfere with it until she was in a receptive mood for a really long, slow, fuck. If there had been any residual energy after Linda had collapsed from fatigue I would have been only too pleased to wear myself out screwing Helen.
That plan crumbled to dust as I viewed the scene before me. All I could think of was that for a 'plan B', it had a lot going for it.
My attention was now riveted on one fantastic bottom pumping forward and backward with her pink slit visible between her thighs and buttocks. The fact that I could also see what she was pumping into was icing on the cake.
They were for too engrossed in what they were doing to realize that they were not alone. The first Helen knew of my presence was when I held her soft bottom cheeks apart, pushed my erection between her buttocks and inserted it into her vagina.
She jerked; which caused Linda to receive a much stronger thrust against her cervix, which caused her to open her mouth to complain and thereby let go of the engorged nipple she'd just started to suck, and say:
"Peter; don't you dare stop her. OOHH fuck, OOHH, don't you dare stop her. OOHH. You're doing exactly what she wants you to do. She said she wanted you to, OOOH, fuck her again. OOHH AAGH, before we go back to Uni, but you could have waited for me to have my treat, OOH."
I held Helen's hips and shoved my cock into her. When my groin smacked into her bottom it forced her forward and rammed the dildo down Linda's vagina.
Helen humped her bottom backwards as I pulled on her hips and withdrew my cock before ramming it back into her waiting vagina thus causing her to ram her dildo back into Linda's slurping love tube.
Linda cried out:
"OOOhhhh this is heaven; fuck her OOHH, harder Peter. She fucked me last night and it was so good to have her do that, but this is so fucking erotic. I want more.
"Fuck her Peter; AAGH OHHH, screw her until she cums OH FUCK, and then use her AAGH, anus. She fucked mine and I OHH FUCK, want to see her face when you shove your cock into hers."
A hand came round my waist; it was holding a slim dildo which was wet with what I assumed was lube. The dildo slid past Helen's sphincter and it appeared to have no trouble at all in sliding down Helen's anal canal until there was only the bulbous end protruding from her anus.
Linda spoke; "Mum, AAGH, why are you here?"
"I came for Helen, but as Peter has beaten me to it, I'll wait for him to tire and then I'll take her into the other bedroom, Eve is warming the bed up for us. We'll entertain her while Peter sorts you out."
I can take a hint. I began to fuck Helen as hard and as fast as I could. She began screaming and yelling just the same as Linda had, because of the dildo up her rear which was pressing the wall of her vagina against my swollen and thrusting cock. This was causing sensations she had certainly never experienced before.
Linda was telling her how much she enjoyed the proceedings, when, for one last time she yelled:
"OH YES, OH FUCK, I'M CUMMING, OOOH that is soohh..."
I pulled my still swollen cock, and the dildo, out of Helen as she slumped forward onto Linda who was now busy trying to extricate herself from Helen's embrace. This left me with the problem of; what to do with said swollen cock?
Donna was close. It would be a waste not to combine those two facts. Before she had time to react I pushed her onto her back alongside her daughter. I was so concentrated in pushing her skirt up to her waist that I didn't realize just how quickly her legs had opened to present me with an unmissable target.
I entered her, slowly. I savoured every moment of sliding down her tunnel whilst fondling her gorgeous breasts. We began to fuck with a slow steady pace and then I noticed that, once again, Linda was on her back with Helen between her thighs.
She was being screwed with a steady rhythm to which I adjusted mine and we grinned at each other as we screwed mother and daughter.
Mother and daughter turned their heads to face each other and smile as all four of us gasped, grunted, moaned and sighed to our individual climaxes.
Eve applauded from the doorway and announced that as it seemed unlikely that Donna was going to return to her bedroom with Linda, she'd taken the liberty of fetching bread from my house and was now about to make coffee and toast for all. After that she would be quite happy to hear the descriptions of what had happened.
Once the pre breakfast snack was over we dressed in order to return to our original departure points in some semblance of decency to shower and change. Eve of course was not as tired as the rest of us so she caught the washing-up and laundry detail, and anyway, it was her house.
I went back to my own bed and slept for the rest of the morning. On the way back I did notice that the cabin cruiser had left.
