You have a brief thought of what Lisa would think, but it quickly disappears. Instead you feel you boner surge and you give in to your temptation, a wide smile stretching across your face. You look over the giant beauty laying next to you, look up into her eyes and say "Yeah, I'll show ya".
Tina giggles excitedly and quickly grabs you, her fingers pressuring you boner, adding to the feeling. She kisses you harder than you expected, and after a good 5 minutes, releases you.
Your face is a little wet. "I thought I was showing you haha" You laugh, for what feels like the first time in ages.
"Oh uh sorry I didn't mean-" She starts.
You interrupt her "No, no its good, really! Just if you grab me I cant kiss you back as well" You smile, eager to get back to it.
"Oh okay!" She rolls onto her side, allowing you to freely kiss her. After taking in her incredible beauty once more, you rush over to kiss her as passionately as you can, caressing her wall sized cheeks as you do.
You briefly contemplate one of the few benefits to this size; you can kiss as hard as you like.
After a good 15 minutes, you are about 80% satisfied. You stop after a final passionate kiss and step back a second.
"Ohh Jason that was mmhm amazing" She croons, clearly as pleasured as you are. "I think your size must make you the greatest kisser in history uhmme" Her sounds are music to your ears, and kick your boner into overdrive
You are again briefly thinking of Lisa, but only to remember your final step when you would make-out, excited to do the final step with Tina.
"This is the part where I finish; Lisa would watch me and pleasure herself so we could both finish simultaneously" You quickly begin to satisfy your boner, and she just as quickly puts her hands into her shorts and does like-wise.
As you get closer and closer to euphoria, your movements and reactions make her get more aroused, making her pleasure herself more and more force-fully. She begins to moan and coo, indicating she is again just as close as you.
The more she shakes the bed, the more you're turned on, creating a runaway excitement cycle. You are forced to sit as her gyrations become like an earthquake, only taking you even closer to euphoria. After just 2 minutes, you both finish at the same time, locking eyes with one another, smiling, and then laughing as you both catch your breath.
You return to kissing her, and slowly fall asleep by her cheek, happy that Tina was able to take you away from all the troubles of the big world you live in.
