Her mouth

After a dreamless sleep you awoke to a familiar sensation, Iris had her lips wrapped around your cock which was getting harder by the moment.

"Hey there," she said as you came to, "ready to try something else?"

"Yeah," you said enjoying the feeling, "what did you have in mind?"

"I want to put it inside," she said, "I know that's like crazy but I don't care."

Sex? You thought to yourself, it was a sin, although all of this was probably sinful. Pragmatically though, what if she got pregnant.

"I'm on the pill," she said, "please?"

"Ok," you finally offered.

She straddled you and brought your cock up towards her vagina and slowly brought it down onto you. At first she paused once the tip was in then after sliding down slowly she paused once she was halfway down. Finally she slowly slid down taking your full length into her. If her mouth had felt like heaven this was something beyond.

"Fuck," she gasped, "I feel so full."

She leaned in and kissed you slowly grinding her hips on you. As you kissed your hands found her breasts squeezing them as Iris worked her hips. Iris grabbed your hand pulling it down to her vagina and it was easy to guess what she wanted. You pressed your thumb to where she'd steered your mouth before and began to rub circles on her as she continued to grind her hips on you.

The stimulation got to be too much for Iris her vagina contracted around you as she shook before pulling your hand away from her vagina. She collapsed onto you gasping for air before looking up at you.

"Push it into me," said Iris.

Grabbing her waist you slowly started to push yourself into her before pulling back out. Slowly you picked up the pace drawing a series of moans from Iris. As much as you wanted to keep going you felt your own climax approaching.

Iris seemed to recognize the look on your face, "do it, I want it."

A few strokes later and you shot into Iris holding her tight as you buried your cock in her. Once you finished she leaned in and pressed her lips to yours.

"I'm so glad I took the train," she whispered before resting her head on your chest.

After two days and nights of more fun with Iris the train pulled into the station in San Diego.

"This has been fun," said Iris as she pressed her lips to yours.

"It's been wild," you said holding her against you.

"When you get settled," she said, "give me a call, "I'll probably hang around for a while before I try to hitchhike up the coast."

"I," you started, embarrassment returning, "don't have a cellphone."

She smirked writing her number down on a napkin and shoving it into you pocket, "I've been away from home for two days, and I already feel like a new person. Thank you," she said running her hand up your groin.

A while later you were on another bus pulling onto campus.
