This work suddenly begins with a scene of caressing jeans, immediately drawing viewers into a first-time experience. Since it was filmed as a practice session with Aimi-chan, we hesitated whether to release it, but decided to sell it due to her small yet dedicated fanbase. For this release, she wore panties she really liked—borrowed from another girl—and loved them so much she bought multiple pairs in different colors. This time, she wore a different color variant, and while enjoying the feel of her ass, we practiced assjobs. However, as she grew tired, we switched over to handjob. Since we're close and comfortable with each other, making requests was easy, and she happily accepted handjob while I watched her ass. Her cowgirl-style handjob technique is excellent, delivering a handjob sensation with a tight, vacuum-like feel similar to a fleshlight. The sounds are erotic and she seems to be enjoying it immensely. At our place, it's rare to cum onto a prone, flat-lying ass, and while feeling the softness in that position is amazing, it doesn't compare to the powerful appeal of a lifted, protruding ass. Since it was practice, she was a bit lenient with me. Actually, she had given me a handjob two days prior, so my semen volume was slightly less than usual, but she happily showed me the spurting action in a quadrupedal pose, so everything worked out in the end. It's our habit to go out for a meal before or after filming, so this time we went to eat seafood.
