My travel week had come around again. It had been almost a month since the first adventure with Carla. She had stayed over twice more. My girlfriend and I had enjoyed her admirable skills with her hands and tits to add to the impressive repertoire we'd already learned about. She'd also introduced my girlfriend to a complete new range of toys; devices which, in my girlfriend's words, gave her massive orgasms but left her sore for days.

I liked my travel weeks, but I'd stayed in the hotel too many times before. I knew the room service menu by heart and backwards. My back hurt from the lousy car seat. A hot shower had helped a little, but I was tired. The biggest decision I wanted to make was which of the unhealthy menu options to choose.

There was a knock on the door, "Room Service." I checked I was decent in the towelling gown then opened the door. "Not me, I'm afraid."

Carla stood in the doorway in a long, flowery dress, which showed her cleavage to excellent effect. "Maybe not, but I know what you'd like right now."

She brushed past me into the room. I closed the door. "Your girlfriend let slip where you'd be staying. I can be quite persuasive." I’d guessed that they were now sharing a bed when my back was turned. I was also completely sure that Carla had excellent powers of persuasion. "Pleased to see me? Oh yes, I think you are." She stood a couple of paces away and reached inside my gown.

Carla looked me straight in the eye. Her soft hand worked its magic. She stopped, smiled, then lifted her dress over her head. She stood, legs slightly apart, in just a tiny pair of pink knickers. She kicked off her shoes and stepped forward to undo my gown. "Very pleased now, I think."

Carla was on her knees in a second before I could do the gentlemanly thing and offer her a pillow to kneel on. I knew from experience what her oral skills were like. She went straight to work, kneading my balls while she kissed and licked all around the tip of my cock.

She stopped, looked up at me, and backed off. She squeezed my balls and said, "Now, don't come until I say so," before wrapping her lips around me and taking half of my length into her warm, soft mouth. She pressed a fingertip into the base of my shaft and swirled her tongue around me before rubbing my tip against the inside of each cheek in turn. Without moving her head, she started to suck. Hard. It was all I could do not to fill her mouth there and then.

Carla held me like that for what seemed like an age but was barely a minute. She started to bob backwards and forwards, sucking harder each time she pulled away from me. She ran her tongue around my cock head and suddenly plunged it to the depths. I felt her change position slightly and then the tightness of her throat as she finally took my entire length. Carla bobbed slightly, keeping me in that tight tunnel.

She pushed back away from me and looked up. "Next time, you will fill me with your hot, sticky cum, you hear?" She engulfed me again, working me in and out of her, sucking hard all the while. I put my hand behind her head to pull her closer when I felt myself losing control.

"I'm coming," I whispered, as if there could be any doubt. I shot stream after stream into the depths of her throat. Carla pulled away very slightly and sucked so hard I thought my balls would come out. She took every drop. I felt her swallow hard as her throat contracted around me.

Carla eased herself up, stepped back, and lay back on the bed. She arched her back slightly as she supported herself on her elbows. The effect was to thrust those fantastic, soft, round tits upwards. I spread her legs and knelt between them. I leaned forward and licked her right nipple before moving across in a series of butterfly kisses to the left. She arched her back more, and I took the stiffening button into my mouth and sucked it hard. Carla moaned gently. I moved across in case the other was feeling neglected and repeated. I moved my attentions into the valley between the mountains, kissing up and down the foothills, under and between her tits. "These would suit a pearl necklace," I said.

"Later," she said breathlessly, "much later, if you are a good boy."

I kissed her all down her soft belly until I reached the waistband of the tiny fragment that passed for her knickers. I worked left then right, lowering it and kissing the marks in her soft skin. I lifted her legs and lowered the flimsy garment. With a practised flick of one foot, she kicked them off. I moved lower, kissing her shaven mound, taking in the musky scent.

Carla raised her legs onto my shoulders, and I lowered my mouth to her welcoming, swollen, pink lips. I licked all around her slit then buried my tongue in her. She shuddered. I probed deeper, working all around, feeling her juices run onto my face. I pulled back and inserted two fingers into her, gently working them inside her. She yelled as I found just the right spot then started to buck as I worked my fingers backwards and forwards and all around it, gradually going faster and pressing harder.

Carla thrashed, driving her hips upwards to engulf my hand. With one push, she screamed and lifted her legs, pointing her toes to the ceiling, then squeezed with all her muscles. She gushed all over my hand as she screamed. I freed my hand and placed both on her tits, massaging them, hard. "Fuck me, you bastard," she yelled.

With one leg on each shoulder, I moved forward, bending Carla over almost double. She pushed her hips upwards into me; my rock-hard cock almost fell into her hot, slippery pussy. I drove in hard, and she locked her feet behind me, bucking. My balls were slamming hard against her as I drilled her depths. Suddenly, she went rigid and squeezed her legs tightly around me, then she started to moan, rocking her hips backwards and forwards. I started to move with her, my cock pushing into her as far as it could.

She came hard. I felt her muscles pulsing all around me. I drove deep into her again. Carla tensed everything, clasping me, forcing me over the edge, filling her with what felt like pints of hot cream.

Carla spoke first as we lay with legs and arms entwined. "That felt like I was being split in half. I'll get properly dressed. Bar next, then dinner, then more of this." She was truly unbelievable.

Dinner was average in the way that only business hotels can manage. Carla amused herself by flirting outrageously with the waiter, who spent most of the evening scarlet faced. "Serves him right for looking at my tits," she said, just a little too loudly. I’d been the one who was most guilty of gazing at the full, round orbs that were scarcely concealed by her dress.

She got up from the table. "My room," she said, "you can be the one sneaking back to yours in the morning. Leave it five minutes."

I did as I was told. You'll have to wait for Part 5 of the story to hear what happened next.
