Erica placed her hand on his chest while kissing him and she could feel how fast his heart was beating too.
After a while they broke the kiss as they were short of breath and Erica said, "Your… heart is… beating… very fast"
"I… Know" Steve knew his heart was beating faster, it always did when Erica was around him.
"Why is it beating so fast?" She asked him.
Steve chuckled, "Why do you think it is?" He asked her and before she could answer him, he again kissed her, this time roughly.
Erica tried to keep up with his kiss but he was not letting her as if he intentionally didn't want her to keep up with him.
Steve bit on her lips and kissed her hard.
Erica broke the kiss and moved her head away, "Why is your heart beating faster?" She again asked him as that was the whole purpose of her plan.
Steve placed his hand on her chest and Erica turned embarrassed as a part of his hand was touching her bosom.
