She gives you a blowjob (and something extra)

Almost immediately, I unbuckle my pants, so that my cock would fly out, erect and exposed before Yuuko's eyes. Initially she continued, but her attention would soon be brought to me.

She then wraps her lips around my shaft, bobbing her head up and down as I watch her go to town. She looked up at me with wanton eyes, continuing her movements before temporarily taking my dick out of her mouth.

I ask her, "Are you thinking about titfucking me?"

Yuuko nodded, but said, "I don't know how to do it right, though."

Taking each of her breasts, I slide my cock in between them. This caused her to nearly gasp as she found my shaft sandwiched by her perfect pair, before she rubbed them as she resumed sucking my cock.

"Hey, Yuuko," I ask between grunts, has your boyfriend ever played with your tits?"

She blushed, and replied, "Maybe after I'm done, I'll answer your question."

By then, I closed my eyes, feeling the urge to release. Grunts and groans escape my lips as I thrust forward, giving her her very first titfuck.

Yuuko brought her gaze up to me again, earnestly waiting for me to reach climax. Eventually, I grant her wish, my cum exploding onto her face as well as her tits.

I slide my cock out from the valley of her breasts, and Yuuko eventually replied, "He'd only suck them gently. I could tell he was quite turned on by how big they were. Now,"

She gets on all fours, facing the couch, and with her ass in front of my view, as well as her pussy still soaking a bit from her masturbation.
