How about a blowjob

Teresa looks at you hungrily and says, "I've always loved giving oral, I want your whole cock in my mouth." You look at her for a second stunned but quickly get over your surprise as you push yourself up off the bed. Standing you quickly strip out of your clothes as Teresa kneels at your feet excitedly.

She looks surprised as your full length of 11 inches pokes out towards her face. She wraps her right hand around it at the base but her fingers can't reach around the whole width. She starts by pumping it a few times until a little bit of pre-cum starts to leak out. She licks a little bit off the tip of your cock but spreads the rest up and down its length to make it slicker. Finally after teasing your head with a few licks she quickly gobbles the whole head at once and begins to suck as hard as she can. Teresa starts to slide the end of your cock in and out of her mouth all the while applying a considerable amount of suction. She can only get the first few inches in because of the width but she is extremely enthusiastic about the whole event as she makes loud slurping sounds.

It all feels so good as she slips your cock in and out of her mouth and occasionally will stop so she can swirl her tongue around, paying special attention to the cock head. After about 10 minutes of this you're already feeling the urge to blow your load in her mouth but your unspoken wish comes true as she stops, looks up, and says, "Face fuck me as hard as you can, and don't pull out when you cum... I want to eat it all."

Without a moments pause you pull her blonde hair behind her head with your hands so you can see more of her face. With both hands firmly on the back of her head you begin to **** her farther onto your cock than before. Teresa deals with it fine at first but as you pick up rhythm all concern for her leaves your mind and you begin to jam your cock farther and farther in her mouth. It feels so good as you're sliding in and out faster and faster that you ignore the gagging sounds and just keep on going, after all this is part of the face fucking she asked for. Finally as your cock head begins to ram into the back of her throat and starts to go down her esophagus the noises start to get louder and louder. As your approach orgasm you jam your cock in one last time and hold her head in place more than half way on your cock as the pressure builds. Already her face is bright red and getting redder as you blow you cum straight down her throat. You hold her there for a few more moments to make sure your cock is completely drained before letting her go.

She nearly collapses and gasps for breath on the floor. Now the reality of what just happened is setting in, and you check to see if she is alright. When you ask she responds with a really big smile and says between gasps, "That was amazing, I almost thought you were going to **** me."

Well it didn't seem like she was mad or hurt so you quickly dress yourself and leave for the rest of the party.
